It’s been a while since we decided to work from home, which has completely disrupted our daily pattern and may reduce the amount of sleep we receive. A study last September 2020 found that 25% of Americans had noticed a reduced sleep quality due to COVID-related stress.

The capacity to get enough sleep is affected by a variety of factors. For example, people with asthma may experience fewer symptoms, harmful airborne compounds may be removed, and unpleasant odors may be neutralized if more outside air is let into the bedroom.

Think of the Kids

Recently, scientists demonstrated that kids exposed to high levels of air pollution had trouble sleeping. Air purifiers, a popular household appliance that has seen a surge in sales since the epidemic began, help keep indoor air purifiers healthier for those who live there.

Nothing is more annoying than a noisy air purifier, especially if you have newborn or young children in the house.

Are They Noisy?

Air purifiers, even when set to their quietest setting, can generate noise levels of around 20 decibels, or about the same as the rustling of leaves. It is possible that an air purifier, when set to its loudest setting, will generate noise levels of around 60 decibels, which is about the same as the volume of a normal conversation.

Manufacturers typically do not include decibels in their suggestions because, according to a spokesperson, the decibel range of a device may change based on the area in which the purifier is used. However, quiet purifiers often operate in the low decibel range, making them preferable for some homes.

The idea is to help clients discover a model that makes a sound that is either pleasant or non-intrusive, one that can easily integrate into the environment and won’t be a cause of attention, even if there is no such thing as an entirely silent air purifier. In the case of air purifiers, for instance, two models with comparable decibel levels could fail certification because one model produces a more annoying sound than the other.

Here are some of the five most efficient and quiet air purifiers you can use for your home. Aside from this list, please check out Iupilon’s post regarding “The 3 Most Cost-Efficient Air Purifiers,” “The 3 Most Efficient Home Air Purifiers,” and “The 3 Most Efficient Whole House Air Purifiers.”

Are Air Purifiers Supposed to be Quiet?

The volume produced by an air purifier varies with its dimensions, features, and manufacturer. The larger the air purifier, the noisier it will be, but the larger the room, the more powerful the purifier will be. Air purifiers integrated into HVAC systems make hardly any noise at all.

The Main Benefit

Air purifiers are a fantastic way to combat rising levels of pollution, allergen-causing pollen, and potentially dangerous germs in your home’s air. Many people, however, question whether or not they may be used as tranquil sound machines in addition to being just another noisy device.

Where Does the Sound Come From?

The air pressure pulses released by a vibrating item are what we call “sound,” They are detected by the ear and processed by the brain. What we call “noise” is sound that isn’t wanted. Sounds to one person are noise to another; however, there are some sounds that most people find annoying and so label them as noise. Mechanical noise is broadly defined as the sounds of devices like air purifiers.

It’s White Noise

Air purifiers produce a soothing, white-noise-like background noise that is appreciated by many. Some people have reported that it works like a white noise machine lulling them to sleep. However, the noise can be distracting for some people who are trying to relax or watch television.

Decibels are used to quantify the loudness of a sound. What we understand as “sound” is heavily based on mathematical and scientific principles. We won’t bore you with the specifics, but there’s an excellent essay on the subject in the Britannica if you’re curious. The decibel level is our main concern here.

The human ear is nonlinear, allowing us to process soft sounds more effectively than loud ones. Most people, for instance, don’t mind hearing leaves crunch underfoot, but they might be annoyed by the sound of a ringing bell or a lawnmower.

What’s the Noise Range?

Regarding decibel levels, air purifiers can range anywhere from 15 to 75. That’s a substantial dissimilarity. From what we can tell, the volume increases as the size or cost decreases. This, however, does not negate its ability to remove unpleasant odors and refresh the atmosphere. In this case, loudly implies that it makes a lot of noise.

Industrial settings are commonplace for the massive ones. The most commonly advertised varieties are bedroom, nursery, and living room air purifiers. The manufacturer typically provides the decibel rating, so you know what to expect regarding volume.

Which Air Purifier Is Most Efficient and Quiet?

A quiet air purifier is a way to go if you want to eliminate hazardous chemicals in the air without disturbing the peace. So, you can use it in your soundproof room for undisturbed sleep and productive work.

The Rise of Air Purifiers

In addition to being the area where you do the majority of your living, your house also serves as a place of worship, a place of meditation, a place of relaxation, an office, a playground, and a place to eat. You seldom ever go somewhere else, so much time is spent there.

Yet few property owners appreciate that cleaning entails more than just washing and sweeping. When indoor air quality is improved, household health is positively impacted. Unfortunately, dust, pollen, and smoke are some of the many common culprits of indoor air pollution.

There has been a steady rise in the popularity of the once-inconspicuous air purifier over the past few decades. It has progressively become a standard in many urban houses due to its unparalleled capacity to purify indoor air.

The Range of Sound of Air Purifiers

The volume of an air purifier can range from hardly audible (blending in with the backdrop) to deafening. The decibel level produced by different models varies with their respective fan speeds. With the fan set to a lower speed, the noise it makes is diminished—the volume of the noise produced by a fan increases as its speed rises.

Nearly all commercially available air purifiers have vertically oriented discharge vents. Outlets in tower units are front-facing. Because we placed the sound meter largely above and very slightly in front of the control panel of each unit we tested, tower units benefited from this setup in terms of noise output.

What About Tower Units?

Tower units also have a distinct advantage over other types of air purifiers in terms of noise levels: With tower systems, the sound can be aimed in any direction. As a result, the noise will naturally travel in the direction of the freshest air. All other units emit upward, but you can’t point the noise with these.

Furthermore, larger units with more prominent outlets will be noticeably quieter for the same output than smaller units with smaller outlets. In that case, you should seriously consider purchasing a larger unit if noise is an issue. However, most bigger units have adjustable fan speeds that allow for near-silent operation, and at these low noise levels, the differences between specific models are almost negligible.

BLUEAIR Blue Pure 411

The BLUEAIR Blue Pure 411 stands out from the crowd thanks to its distinctive design and easy-to-understand operation. As a result, global recognition for BLUEAIR as a company is high. BLUEAIR 411 is an intriguing option due to its peculiar diminutive size. It is easy to transfer from one area to another, and its straightforward form makes it adaptable to practically any setting.

They’re Easy to Use

Even if it isn’t the best air purifier in the world, the BLUEAIR Blue Pure 411, which comes from the same company that brought you the T3 Award-winning BLUEAIR Classic 480i, is arguably the easiest to use and the one that won’t be as noticeable in your home. Its lightweight and dense design make it ideal for usage in tight quarters or frequent relocation.

The Classic 480i, which is vast and has an office-like appearance, stands in stark contrast to the Blue Pure 411, which is on the other extreme of the spectrum. However, the fact that it is created in Scandinavia and has that unmistakable IKEA vibe, replete with a relatively cheap and fragile sensation, counteracts the fact that it is lightweight and colorful.

Use It Within Limits, Please

If you don’t put undue strain on the BLUEAIR Blue Pure 411, it will do a fine job of purifying the air in your home. But first, it does so in a way that gives you no control over the outcome. So put it down and put it out of your mind.

The Blue Pure 411 is a sleek and straightforward gadget that comes in the shape of a little cylinder made of a rainbow of plastic colors. It has a diameter of 20 centimeters and is just 42.5 centimeters in height. In terms of size and complexity, it’s among the lowest-end options for purifying the air in your home.

The interface is also straightforward. You can toggle between the three available power modes if you click the single button on the top of the Blue Pure 411. The last word, as the saying goes. There are no applications, screens, or blinking lights other than a single red light that alerts you when it is time to change the filter. What we mean to convey is that it is uncomplicated and minimalist.

Simpler Filter Replacement

When it comes to the Blue Pure 411, what else, if anything, is there to know? It’s a good thing that filter replacement is simple because it needs to be done often (at least twice each year).

The filter consists of three layers: an outside filter to remove larger particles and dust, a fine HEPA filter to remove particles and allergens, and a carbon filter to deal with odors and fumes. The outer filter is responsible for removing dust and larger particles.

It’s probably a good idea to keep an eye on it if you’re using it in an area with a higher pollution level because, as far as we can tell, the indicator that tells you it’s time to replace the filter is based on the amount of time that has passed rather than detecting how saturated it is with allergens, particles, and smoke.

It’s a Compact Air Purifier

The BLUEAIR Blue Pure 411 Auto is a lovely and compact air purifier, making it an excellent choice for smaller spaces. In addition, the design’s vented exterior and interchangeable pre-filter skirt will allow it to complement a wide variety of interiors seamlessly. Despite its diminutive stature, it is widely regarded as one of the most efficient air purifiers on the market today.

Our BLUEAIR Blue Pure 411 Auto review will show you that, considering all of its functions, this air purifier provides exceptional value for the money. In addition, it is both portable and lightweight, making it one of the handiest models of air purifiers we have examined.

The company’s most compact air purifier is the 3.8-pound BLUEAIR Blue Pure 411 Auto. It is 17 inches in height. It also has the most diminutive height of any options, at just 17 inches. It has a psychedelic circular top and is very easily disoriented.

As you move downward along the matte white plastic shell, you will come across a textile skirt that also functions as a filter. The first line of defense is this pre-filter, which comes in gray, pink, blue, and green and is fashioned after burlap.

The catch is that it’s not the last line of defense. A HEPASilent filter, which, according to BLUEAIR, can collect 99.97% of airborne particles, and a carbon filter for deodorizing are included in this air purifier.

The BLUEAIR Blue Pure 411 is the most compact and cost-effective model we evaluated, and it’s a strong contender for the title of best air purifier. The machine has a nice appearance and would look great in either the bedroom or the living room; nevertheless, it is compact and lightweight enough to move wherever needed. In terms of capabilities, it performs admirably in a single room of enough size, which is the environment for which it was intended. However, it does not have sufficient power for a vast area with an open layout.

The controls of the BLUEAIR are not overly complicated. There is neither an app nor a remote control for it, nor is there a setting that will do it automatically. To switch between off and levels 1, 2, and 3, you have to tap the circle on the top, and three white lights will show you which setting you’re now using.

The only element that could be deemed missing from this air purifier is smart controls, such as an app or a quality gauge for the air. Since some find this to be overly theatrical already, it’s possible that you won’t miss those folks at all. The fact that this device cannot automatically modify the levels means that it cannot intuitively adapt to any changes in air quality. This is one of the more significant drawbacks of using this device. For this reason, in a bedroom, you could wish to set it on at a high level a little while before bedtime and then turn it down to a low level during the night to keep an excellent air quality without disturbing your sleep.

According to the CADR calculations, the optimal room size for this air purifier is around 190 square feet. When compared to either other models of air purifiers or the Blue Pure 211+ Auto, the 411’s older sibling, this is on the more compact side. However, considering this air purifier’s little, these findings should not surprise anyone.

It was rated 123, 107, and 96 on the CADR scale for smoke, dust, and pollen, respectively. The BLUEAIR Blue Pure 411 Auto can filter these toxins in tiny spaces, even though these values may seem low compared to the other models we evaluated.

Compared to several of the other air purifiers we examined, it utilized an adequate quantity of available power. In the automatic mode, it consumed 154 kilowatts per hour over one day, which, for the sake of comparison, is equivalent to a daily cost of approximately $0.50. However, if you only need to clean a small room, the additional money can be worth investing in a high-quality air purifier such as this one.

BLUEAIR Classic 480i

The BLUEAIR Classic 480i is not a particularly attractive piece of hardware. Still, it is undeniably one of the most effective and efficient air purifiers that money can buy for a vast space. As a result, this device can be precisely what you need if you have asthma or allergies or want the air in your house to be better.

A Truly International Purifier

Even though it was designed in Scandinavia, this is neither an exceptionally stylish nor a particularly space-saving air purifier, as seen. No, the BLUEAIR Classic 480i is more comparable to an industrial gadget that has been manufactured just appealing enough to place in your home. This is especially true if your home contains enormous rooms, which either vanish into the background or may be concealed behind furniture.

Considering the time we spend indoors, an effective air purifier may be a boon to any home, especially considering how much time we spend there. Unfortunately, pet dander, odors, and allergens like dust and pollen are just some of the things that have a detrimental impact on the quality of the air we breathe inside our homes, which can be troublesome for our general health. However, everyone who tried out the BLUEAIR Classic 480i at our testing facility and in their homes expressed their awe and satisfaction with the product.

Energy Star Certified

The BLUEAIR Classic 480i is an Energy Star-certified air purifier suggested for use in rooms of medium size up to 434 square feet. It is equipped with HEPASilent filter technology, which eliminates 99.97% of airborne particles as small as 0.1 microns by employing a wide range of mechanical and electrostatic filtration.

This is a significant concern for you if you have asthma, allergies, or any other health condition exacerbated by poor air quality. Within fewer than five minutes, the 480i was able to reduce the level of particulate matter in the air from more than 50,000 to less than 100 particles per cubic centimeter despite being set to its most powerful setting. This was accomplished by working efficiently.

When our parent testers installed their air purifiers in the bedrooms and basements of their homes, they almost immediately observed an improvement in the air quality in those locations.

How Does It Compare?

The BLUEAIR Classic 480i has exceptional capabilities for filtering the air. This air purifier is simple to operate due to an auto mode that automatically adjusts the device’s settings in response to the presence of particulates in the surrounding air. In addition, it is possible to make simple adjustments or turn the device on or off from anywhere in the world by connecting it to the BLUEAIR Friend app over Wi-Fi.

We can find the Dyson Pure Cool Tower in the same price range as the Dyson Pure Cool Link. Both of these products are air purifiers. Besides having a True HEPA filter, these air purifiers have incredible cooling fan power to assist you in making it through the warm summer months. The Dyson Pure Hot+Cool will have both cooling and heating capabilities, but its price will be slightly higher.

The BLUEAIR Classic 480i maintains the same layout and dimensions as its predecessor, the BLUEAIR Classic 405, which we are familiar with. This indicates that it maintains the exact height of 23 inches and the same width of 20 inches, making it a size comparable to that of a Classic 280i or Classic 680i, considered medium size.

The BLUEAIR Classic 480i has been modified to include the modern design DNA, such as an air grill, taken from both sides. This design maximizes the airflow system’s efficiency from the rear to the front, which is a significant benefit for the Classic series. On the other hand, manufacturers of mid-range and high-range air purifiers tend to shy away from using this air flow method. A typical air purifier that costs $600 will utilize either a bottom-to-top air flow system or a 360-degree airflow system.

The BLUEAIR Classic 480i only has a few buttons and LEDs concealed by a flap on the top of the device. The other button enables the automatic mode, while the first button cycles through the three different power settings. Once you have set the device to operate in automatic mode, it may be the last interaction you need to have with it until it is time to replace the filter.

There are also a few simple, backlit symbols that will notify you when it is time to change the filter, what pollutants it has discovered, and whether or not the Wi-Fi is connected. This is a large purifier for interior spaces that are rather vast since it can clean the air in a room that is 40 meters squared in just 12 minutes. This air purifier is also pretty silent most of the time, so if you don’t care about its size and appearance, it could theoretically go anyplace. However, if you put it in a small space, it might be too overbearing.


Although it does not come with a remote, the BLUEAIR 480i is Wi-Fi enabled and can be used in conjunction with the BLUEAIR Friend app. Parents have said that they enjoy using the app, which allows them to check the air quality within their home, control the machine remotely, and obtain data regarding the air quality outside their community. Downloading the app and linking it to the machine is simple. You can activate the kid lock feature, set the auto mode, modify the fan speed (there are three), and adjust the LED intensity. You can even make daily nighttime settings.

Before purchasing one, you should always consider the noise produced by an air purifier, which is especially important if you intend to put the device in or near a bedroom. For example, the BLUEAIR Classic 480i was virtually silent when our parent testers utilized the low option, and it was hushed when they utilized the medium setting; however, when they utilized the high setting, the unit was rather noisy. However, if you use the app and play around with the settings, you will find that you have the option to configure the device to run at a low or medium setting while you sleep.

The assembly is nearly as uncomplicated as one could hope for. To install the supplied filter, you need only remove the shrink wrap from it and insert it into the vast cavity found within the beast. You can purchase a carbon filter that can remove smoke from the air, or you may use a particle filter that removes dust, allergies, and other particles. If you use it in the kitchen, you will need the “SmokeStop” variety, which will cost twice as much as the ordinary particle filter.

Control can be exercised through an app or even through voice commands issued through Alexa, and establishing a connection to Wi-Fi is a breeze. After initial setup, the BLUEAIR app provides an overview of the air quality in your location at this very now and throughout the preceding days and weeks.

In addition to that, it displays the power setting that is currently in use, as well as the auto mode and the amount of time remaining until the filter needs to be replaced. The fact that this is expressed in days makes it appear not very optimistic; however, given that you probably won’t be using the BLUEAIR Classic 480i nonstop, the filter will have a longer life than it appears to have.

Dyson Pure Cool Link TP02

One of the most notable examples of Dyson’s air purification technology is the Pure Cool TP02 model. In our tests, it worked remarkably well, lowering PM2.5 levels to 0.2 while simultaneously lowering AQI levels to 0. In addition, the auto mode on the Dyson, the remote control, and the Dyson Link App make the TP02 simple to operate. It’s not the cheapest air purifier out there, but when you factor in its performance, quality, and ease of use, we think it’s still a good option overall.

A Sophisticated Dyson, Indeed

As expected, the Dyson TP02 is the more sophisticated Dyson Pure Cool Tower, which cleans and intelligently cools you. Today, Iupilon gets the opportunity to test out this older model. We hope our Dyson TP02 Review will provide you with the information you need to differentiate the Dyson TP02 from the company’s flagship model, the Dyson TP04.

Although you can buy air purifiers that are larger elsewhere, the Dyson TP02 is comparable to air purifiers that are far more expensive in practically every other respect. The device is no longer the most advanced model in the Dyson Pure Cool Tower line; consequently, the price has been reduced, making it much simpler for us to acquire.

Are There Alternate Picks?

Alternate options, like the Dyson TP02 and Dyson HP02, are worth looking into if the hefty prices of today’s flagship air purifiers make you feel uncomfortable about the state of your pocketbook. However, they are significantly more affordable than the flagship models of Dyson’s fourth generation, which are the Dyson TP04 and Dyson HP04.

The Dyson TP02 has every smart feature that can compete with the most recent flagship model, including the Wi-Fi Enabled Connectivity feature and the capacity to be connected to Alexa. As a result, you will like the previous flagship from Dyson just as much as the more expensive TP04 model, even though the official price will be $499, and you can receive a price reduction from our deal.

A Mid-Range Champion

It is still an air purifier that belongs to the mid-range market, and it competes directly with Wi-Fi Smart devices such as the AIRMEGA 300S and the Blueair Classic 405. You can also discover the Inofia PM1608 at a discount, which is a perfect alternative to the enormous Dyson TP02 and can be purchased simultaneously.

It also uses the same concept of air movement from the bottom to the top. Its air intake is designed with perforated holes, which allows it to improve its efficiency at capturing significant pollutants such as hair, dust, and fur. In addition, the air intake is 360 degrees, which means that the Dyson TP02 can take in more contaminated air in a single place.

You need a purifier fan with simple controls to operate if you own your own home. And what other equipment could compete with this Dyson purifier fan? You can choose between the remote control or the Dyson Link app as your control method. Thanks to these control options, you can get the appliance from the convenience of anywhere you choose. There is no requirement for manually adjusting the parameters in any way.

It’s a Nice Tower Purifier

The tower shape makes it aesthetically pleasing and allows you to position it anyplace in your home. The fan and the air purifier don’t have any blades. Instead, the bottom of the device is where high-efficiency filters are located and act as the air intake for the device. At the same time, it releases fresh air from the amplifier, which is the part that is located at the top.

The HEPA filter in the Dyson TP02 ensures that allergies, dust, pollen, and other particles are captured and do not make their way back into the air in your room. In addition to the HEPA filter, it also features activated carbon that removes VOCs, smoke, and any other odors that may be present in the home. This aids in preventing respiratory diseases such as asthma and other allergic reactions.

The Dyson TP02 contains an activated carbon filter and a glass HEPA filter that rotates 360 degrees. They ensure that dust, allergies, bacteria, smoke, and other irritants are removed from the environment. Because of this, the purifier fan has the potential to purify the air to an exceptionally high standard.

Dyson Remote Management

By installing the Dyson Link app on your mobile device, you can monitor and manage the Dyson TP02 from virtually any location. You will receive notifications without having to do anything manually if you use the application. In addition, you can establish and manage cleaning schedules for the air, check the air quality in your house, and link a voice assistant. This air purifier is compatible with the voice assistant feature of the Amazon Alexa smart speaker.

Uninterrupted airflow that has been cleaned and recirculated throughout your home. This ensures that the other areas of your room are thoroughly cleansed and that clean air circulates throughout the space. Because it has an automated nighttime mode, this gadget can be used at night. In addition, this option dims the display on the purifier fan and guarantees that the fan operates very quietly. Thus, it won’t bother you as you sleep.

You can turn the Dyson TP02 on or off using the automatic mode, which also monitors the air quality inside your home. When it detects that the air quality is low, it activates the air purifier; when it detects that the air quality is good, it deactivates it. It won’t be easy to clean when you have an air purifier with rotating blades or grilles. The TP02, on the other hand, does not contain any of these features; hence, it is risk-free and easy to clean.

The $499.99 Your home’s air quality can be improved with the help of the Dyson Pure Cool Link Air Purifier, a fan that connects to Wi-Fi. It does all these things by employing several sensors, a motor, and a HEPA filter that rotates 360 degrees to check the quality of the air inside, automatically removing pollutants and blowing air. Unfortunately, when turned up too high, the fan may become quite noisy, and our testing revealed that the app that controls it has some connectivity troubles. However, if you aren’t concerned about the expense and are searching for an air purifier that is both stylish and technologically advanced, the Dyson Pure Cool Link is an alternative worth considering.

The skyscraper lacks any distinctive characteristics except for its straightforward and contemporary form. It can be wiped off and cleaned quickly and programmed to oscillate to assist in air movement around the room. An embedded panel can be found on the front of the base, near the bottom. This panel contains a power button and an LED indicator that flashes different symbols depending on the state of the Wi-Fi connection: when it is in pairing mode when it is connecting, and when it is connected. When the mode is changed to Automatic, the base will show a constant white A while it is the cleaning and a constant green A once the desired level of air quality has been achieved. When the device is set to Night-Time mode, a crescent moon symbol will appear on the screen.

Although you can buy air purifiers that are larger elsewhere, the Dyson TP02 is comparable to air purifiers that are far more expensive in practically every other respect. The device is no longer the most advanced model in the Dyson Pure Cool Tower line; consequently, the price has been reduced, making it much simpler for us to acquire.

Alternate options, like the Dyson TP02 and Dyson HP02, are worth looking into if the hefty prices of today’s flagship air purifiers make you feel uncomfortable about the state of your pocketbook. However, they are significantly more affordable than the flagship models of Dyson’s fourth generation, which are the Dyson TP04 and Dyson HP04.

The most exciting part? The Dyson TP02 has every smart feature that can compete with the most recent flagship model, including the Wi-Fi Enabled Connectivity feature and the capacity to be connected to Alexa. Therefore, you will like the previous flagship from Dyson just as much as the more expensive TP04 model, even though the official price will be $499, and you can receive a price reduction from our deal.

LEVOIT Core 300

The Core 300 by Levoit is an air purifier that can filter the air just as efficiently as more expensive models but costs less than $100. This had been considered impossible before. To deal with allergens like pollen and dust in an average-sized room, the Levoit Core 300 is the obvious solution. Since it lacks frills like an app or built-in air sensors, it can deliver such performance at a low price.

An Innovative Brand

To maintain its position as a market leader, Levoit is constantly innovating, developing new technologies, and incorporating updated, innovative features into its ‘S’ line of units. The Levoit Core 300 will be sufficient for most people, but if you have issues with smoke and volatile organic compounds, you must invest in a larger unit.

The air purifier’s dimensions are roughly 9 inches in diameter and 14 inches in height, making it a tall and slender cylinder. Also, its height is almost 14 inches. The device’s bottom half consists of a mesh screen that pulls in the air while the upper half emits a purifying vortex.

The top of the unit house has a very responsive control panel for the unit’s sensitive touch interface. In addition, there are three fan speeds, a sleep mode, timers, and the ability to turn off the display, so you can customize your experience as you like.

The most excellent air purifier for a large room isn’t necessarily the one with the highest ratings; the best products come in the smallest packages. And the Levoit Core 300 delivers on that promise. It may not have the fastest fan speeds, but it filters air from every direction more than makes up for it.

Positioning Matters

Installed in the right spot, the Core 300 can enhance indoor air quality even though it has not been upgraded to provide additional power. You should put it in a space no bigger than 215 square feet, which is still adequate for bedrooms and compact offices. If you do this, you can count on it giving its absolute best performance. Again, energy Star certification demonstrates its common environmental effect.

Even if the Levoit Core 300 isn’t as powerful as the Medify Air MA-112 V2.0, that shouldn’t stop you from buying one of these devices. At a rate of 135 CFM+, it provides even airflow across the room. Considering placing one of these Levoit air purifiers in a smaller space can significantly boost its function.

Levoit’s announcement of the Levoit Core 300 is another blow to the low-priced market segment, over which the company has established a dominant position. This drop follows closely on the heels of Levoit’s announcement of the brand new Levoit Vista 200.

We’re excited to be the first to provide a thorough review of the Levoit Core 300, which, thanks to its impressive performance and sleek design, we predict will soon be the best air purifier you can buy for under $100.

A Highly Popular Brand

Levoit is currently the most popular air purifier brand globally, not only in North America. Excellent customer service and rapid innovation in product design have propelled Levoit to the forefront of the air purifier industry, where it is expected to remain for the foreseeable future. In addition, the Levoit Core 300, with its sleek design and exceptional endurance, is set to shake up the sub-$100 market.

We also measured how loud the air purifier was while it was working. During this evaluation, we put the air purifier through its paces by cycling through its three modes and then measuring the decibel levels produced by the device. The Levoit Core 300, according to the company, is slightly less noisy than the company’s larger air purifiers. For context, the noise level in a quiet library is on the order of 40 dB, whereas the sound of someone breathing is on the order of 10 decibels.

The filter that comes with the Levoit Core 300 has both a HEPA grade H13 filter and activated carbon pellets. The high-efficiency particulate air filter will do a great job of removing impurities like pollen and viruses. At the same time, activated carbon is excellent at eliminating smells and chemicals.

It Has Two Separate Filters

It’s necessary to buy two separate filters because of the blended filter. If the Core 300 were to be put to specialized uses, like cleaning the air of pollution particles, it would be good to have filter renewal options that utilize 100% HEPA or activated carbon.

The filter, a 3-in-1 composite, can remove particles as fine as 0.3 microns (approximately 99.99%). This filter has three parts: a pre-filter, a HEPA filter rated at H13, and an activated carbon filter. The true HEPA filter captures smaller particles like smoke, bacteria, and viruses, while the pre-filter removes larger particles like dust and pet hair.

The Levoit Core 300’s stunningly beautiful exterior, unblemished by the typical small cylindrical shape used in electronics, conceals a few surprises. For example, despite seeming like a brand new, custom-made all-in-one air filter, it hides the most potent fan power currently available for any air purifier costing less than $100.

This is a HEPA Purifier

The Levoit Core 300 has a powerful certified True HEPA filter that can outperform the vast majority of other cheap variants while lacking the additional filtering technology of the Winix P150 and the GermGuardian AC4825. To elaborate, this air purifier can rid the surrounding area of ozone because it does not release harmful UV radiation or ions. Overexposure to ozone has been linked to asthma attacks and other respiratory illnesses, according to the Environmental Protection Agency (EPA).

We at Iupilon are doubtful that any other air purifier brand can compete with the Levoit Core 300 as the best effective low-cost air purifier. In conclusion, Levoit has excelled once more. Compared to the Levoit Vista 200 and the Levoit LV-H132, the Levoit Core 300 is only $10 more expensive. However, it’s very reasonably priced at just $99.

The Levoit Core 300 is an excellent air purifier that removes PM2.5 particles from the air at a low cost. Aside from smoke, bacteria, and viruses, it also dramatically filters out other small airborne particles.

A relatively low learning curve is associated with the machine’s upkeep, and the filter has a relatively long life span of six to eight months. So if you need to clean the air in a room of about 300 square feet but don’t want to spend a fortune doing it, the Levoit Core 300 is a great option.

Germ Guardian AC4825

When looking for an air purifier, it can be challenging to sort through all available options and functions because there are so many. This review will provide you with all the information you require to determine whether or not the GermGuardian AC4825 is the best air purifier for your needs.

Best for Smaller Spaces

This air purifier is recommended for use in spaces no larger than 153 square feet. You just turn a simple switch between three different fan speeds to use it. The air purifier is practically silent when set to its lowest speed, but it may become very noisy when it is set to its highest level. Although it has a pleasant and straightforward style, nobody will be fooled into thinking this is not an air purifier. However, this is not the best air purifier for you if you want something that can blend in with its surroundings.

Compared to the many other smart air purifiers currently on the market, the GermGuardian is an inexpensive alternative. It does not have any innovative features, but it does combine a certified HEPA filter with a charcoal filter so that it can remove dust, allergens, pet hair and odors, and volatile organic compounds from the air. It also does not have any smart features. UV-C light is an additional function that may be added to this air purifier. This feature helps to reduce the number of mold spores, germs, and viruses in the air.

Minimal Installation, Big Gains

The GermGuardian AC4825 is a straightforward air purifier that can be used with minimal effort. This air purifier is perfect for folks who enjoy breathing clean air but don’t want to be troubled with too many options because the control panel has no complex capabilities. Although it has three speeds, the AC4825 is a 4-in-1 air purifier. This implies that it cleans the air using four different techniques rather than just one.

Even if it does not have any particularly innovative features, the GermGuardian AC4825 air purifier is undoubtedly one of the most well-liked air purifiers available on the market. Without a shadow of a question, this particular air purifier is one of the top sellers produced by the Guardian Technologies firm.

Tower Form

According to our initial impressions, the GermGuardian AC4825 appears to have been designed in the form of a tower. This structure, which resembles a tower and can be positioned in restricted spaces, is helpful. The air purifiers that the GermGuardian firm typically produces have this design style since it is more practical, particularly if you don’t have a lot of space in your house, office, or anywhere else you want to put them.

We put a black GermGuardian air purifier through our testing, but if you’re not a fan of the color black and think a white air purifier would look better in your home, feel free to go with that option. The manufacturer offered this product in a choice of two distinct hues.


This particular model of GermGuardian is branded with a black color scheme, and nearly the entire device is colored black. The only part that is silver in color is the top, and it has a blue line that gives off light. The control panel is located on the very top.

However, the only controls available are a button for the UV-C light and a dial for adjusting the fan speed. In addition, there is a port on the rear of the air purifier that can be utilized for carrying it. You only need one hand to carry it with you. The design as a whole is nothing to write home about.

Feature Testing

Because it has intelligent features, the GermGuardian AC4825 is extremely easy to operate. The control panel consists of a single knob that can be turned off up to the maximum speed and a button that activates the UV-C light sterilization.

When the UV-C light option was being tested, our tester found it challenging to discern whether it was turned on or off. A light strip around the top illuminates the device when the air purifier’s UV-C light is turned on or off. In a room with a lot of natural light, you have to look very closely to check if the light is on, but in a room with less natural light, it is effortless to tell.

With a total weight of approximately 8.5 pounds, the GermGuardian AC4825 is a compact and lightweight air purifier. Compared to other kinds of air purifiers, this one is tall and slender, so it may easily be tucked away in a room’s corner.

For optimal ventilation, the owner’s handbook recommends keeping the device at least one foot away from adjacent walls and pieces of furniture. Because this air purifier is designed to clean the air in rooms up to 153 square feet, it is most likely best suited for a bedroom, particularly a kid’s room or nursery.

How Did the Germ Guarding Perform?

We put the GermGuardian AC4825 through its paces in three different types of air: the regular air in the room, the air after 10 matches was burned, and the air after 5 sticks of incense were burned. All three types of air passed our tests. We put each of these scenarios through our battery of tests using both the minimum and maximum settings.

GermGuardian removed 13% of the smallest particles that our air quality monitor measured when the air in the room was expected after 15 minutes on its lowest setting. This number increased to 42.5% after the matches were burned and decreased to 10% of the 2.5-micron particles after the incense was burned. Unfortunately, after the incense burned, there were so many smaller particles in the air that our air quality monitor could not register them all. As a result, we were unable to compute how much smaller particles were reduced as a result.

GermGuardian removed 41% of 0.3-micron particles from the regular air in 15 minutes when it was set to the highest. This number increased to 63% after the matches were burned and 75% after the insenses were burned. In the first 15 minutes of the air purifier’s operation, on the highest setting, it removed a sufficient number of the incense’s smaller particles for us to determine a reduction in the amount of smoke produced.
