The 8 Best Air Purifiers

When choosing the best air purifier, we took into account the most important parameters such as:

  • CADR – Clean Air Delivery Rate
  • Room coverage
  • Device features
  • Quality and filtration methods
  • Performance tests
  • Noise tests
  • Operating cost tests
  • Value for money
  • Application in real conditions

The following text shows short descriptions of the 8 best air purifiers based on the above parameters.

Winix 5500-2 – Our Top Pick

Winix 5500-2 - Best Air Purifier
Winix 5500-2 air purifier.

Winix 5500-2 Highlights

  • The Winix 5500-2 performed well in the performance tests, improving air quality by around 96%.
  • It uses 5 different speeds and has a very quiet sleep mode that produces a sound of only 40.6 dBA. However, it is slightly louder in Turbo mode, producing 66.4 dBA of sound.
  • Although it uses a 70W motor, the Winix 5500-2 is not wasting much energy and is Energy Star certified.
  • With low power consumption, the very long-lasting filters make this air purifier suitable for annual maintenance.

The Winix 5500-2 is the best air purifier you can currently buy. This air purifier has 4-stage filtration consisting of a washable pre-filter, an activated carbon washable filter, a True HEPA filter, and PlasmaWave technology.

When it comes to filtration, the Winix is equipped with PlasmaWave technology. This option is optional, meaning you don’t have to use it, but it is on by default. The Winix 5500-2 is best used in a room up to 360 sq. ft. However, given its outstanding results in tests, I would recommend it for slightly larger rooms.

What sets the Winix 5500-2 apart is its excellent performance, 5 different fan speeds, a very long-lasting filter, and a multitude of advanced options. Advanced options such as an air quality sensor that detects odors in real-time, an air quality indicator, PlasmaWave, auto mode, remote control, and a light sensor are available to make things easier and take the Winix to a much higher level.

I would recommend the Winix 5500-2 for almost any condition, be it to fight pollen allergies, fight mold spores, high dust volumes, and thanks to the high-quality carbon filter, I would also highly recommend it to fight fire smoke and neutralize cooking odors. The minor complaint about the Winix is only a one-year warranty.

Filters Washable Pre-filter, Washable AOC Carbon Filter, and True HEPA Filter
Filter Longevity up to 12 months
Coverage (4.8 ACH) 360 sq. ft.
Power Consumption 70W

Coway AP-1512HH – Runner Up

Coway AP-1512HH - Best Air Purifier
Coway AP-1512HH air purifier.

Coway AP-1512HH Highlights

  • The Coway AP-1512HH performed exceptionally well, improving air quality by about 96% in the tests carried out.
  • The Coway AP-1512HH is also Energy Star certified, but to be honest, it is a slightly bigger energy consumer than some competing air purifiers. Fortunately, a well-optimized ECO mode will help reduce energy costs.
  • Replacement filters are long-lasting, especially the True HEPA filter, so combined with the power consumption, I don’t think this air purifier is very expensive to maintain annually.
  • I would have liked this device to have more than 3 speeds and be equipped with a sleep mode, as the noise produced by the Coway ranges between 41.4 – 63.5 dBA.

The Coway AP-1512HH is the second-best choice after the Winix. I like the Coway, and what I see as an advantage is the air quality sensor that detects dust particles, unlike the Winix, which only detects odors. In addition, the Coway sensor has the option of adjusting the sensitivity. It uses 4-stage filtration, comprising a washable pre-filter, a carbon-coated fiber filter, a True HEPA filter, and an ionizer

The ionizer is also optional on this air purifier and can be switched off if required. I also like that the Coway ionizer is switched off by default. The Coway AP-1512HH covers rooms up to 361 sq. ft. Advanced options include an air quality sensor, air quality indicator, auto mode, ECO mode, and ionizer.

Overall, the Coway AP-1512HH is a high-quality air purifier that will undoubtedly brighten the air in your room. I would recommend this air purifier in any room, especially in the living room, bedroom, or children’s room. In situations where VOC neutralization is a priority, I prefer the Winix air purifier because of its slightly higher quality carbon filter. I would commend Coway for giving this model a very generous 3-year warranty.

Levoit Core 400S – The Best Smart Option

Levoit Core 400S - Best Air Purifier
Levoit Core 400S air purifier.

Levoit Core 400S Highlights

  • Outstanding performance, improved air quality by about 96% in a 320 sq. ft. room.
  • It has a lot of speed and is one of the quietest air purifiers I’ve tried. It is a significant advantage if you need an air purifier for your bedroom.
  • Levoit air purifiers are well known for affordable maintenance, as with this model. The Core 400S uses only a 38W motor (24W for the European market).
  • Low energy consumption, Energy Star certification, and long-lasting, affordable filters are features that make the Levoit Core 400S very affordable to maintain annually.

The Levoit Core 400S is one of the best air purifiers on the list and certainly the best smart air purifier you can buy. The Core 400S connects to the VeSync smart app, which opens up new possibilities for the user and provides an entirely different experience when using the air purifier.

My favorite options are the air quality sensor, the automatic mode, but also the inevitable programming of the device. The Levoit Core 400S uses 3-stage filtration, comprising a pre-filter, a True HEPA filter, and an activated carbon filter. Comparing the Levoit Core 400S with the Winix and Coway, the Levoit still scored slightly lower than the devices mentioned above in the space of the recommended dimensions. This model comes with a two-year warranty. Without a doubt, the Levoit Core 400S is the best Levoit air purifier I have tested so far.

Filters Pre-filter, True HEPA filter and Activated Carbon filter
Filter Longevity up to 12 months
Coverage (4.8 ACH) 403 sq. ft.
Power Consumption 38W
Noise Ranges 42.1 – 59.9 dBA

Alen BreatheSmart FLEX – Quiet and Efficient

Alen FLEX - Best Air Purifier
Alen FLEX air purifier.

Alen FLEX Highlights

  • The Alen FLEX improved air quality by an impressive 94% in a 560 sq. ft. room performance test.
  • It’s one of the quietest air purifiers on the market, and it’s very efficient. Interestingly, the volume on the Alen FLEX does not exceed 53.7 dBA.
  • It’s perhaps quite a bit amazing that such a device runs an motor with only 50W of power, so it’s even more interesting that it’s not a big power consumer. However, replacement filters are a bit more expensive and add to the maintenance costs of this air purifier on an annual basis.
  • I was impressed that the Alen FLEX has the option to activate a lifetime warranty if you subscribe to replacement filters on the Alen website.

The Alen BreatheSmart FLEX is a premium air purifier, initially slightly more expensive than the competition but no less reliable and worth buying. The Alen FLEX is a premium air purifier that uses a 3-stage filter system consisting of a pre-filter, a True HEPA filter, and an activated carbon filter.

What I like about the FLEX is the option to buy different carbon filters that contain more or fewer carbon pellets. In fact, it is possible to buy a carbon filter that has 2+ lb of carbon pellets. I like that this air purifier has 4 fan speeds and that it is one of the quietest air purifiers I have tried so far. That’s why it’s on the list of best air purifiers for the bedroom. This air purifier is best used in rooms up to 300 sq. ft., although the FLEX has shown outstanding results in slightly larger rooms.

Because of its features and high-quality True HEPA filter, I would recommend the Alen FLEX for the living room and bedroom to combat allergies, excessive dust, pet hair, and mold spores. In addition, due to the same quality carbon filter, I would recommend this air purifier in the kitchen to fight smoke or in similar situations where odor neutralization and VOC neutralization is the primary goal.

It is important to note that this is a premium device, meaning that the build quality is top-notch. The filter quality is also top-notch, making the filter price slightly higher than similar air purifiers.

Blueair 211+ – Perfect for Large Rooms

Blueair 211+ - Best Air Purifier
Blueair 211+ air purifier.

Blueair 211+ Highlights

  • The Blueair 211+ showed excellent results in the test, improving air quality by approximately 92% in a 560 sq. ft. room in 60 minutes of operation at maximum speed.
  • At first speed, it is quiet enough, producing 43.9 dBA of sound, but at maximum speed, the sound is slightly louder, which some users may not like.
  • It has a slightly higher power consumer with a 61W motor. If you leave it running at maximum speed, 24 hours a day, you increase your electricity bill by about $4.8 per month.
  • This air purifier comes with a 2-year warranty.

The Blueair 211+ is a large air purifier designed for rooms up to 540 sq. ft.

This minimalist air purifier uses a 3-in-1 filter comprising a pre-filter, a particulate filter, and a carbon-coated fiber filter. In addition, the Blueair features HEPASilent technology, which is the fourth stage of filtration and cannot be shut off. It is important to note that the Blueair 211+ is a CARB-certified air purifier.

The Blueair 211+ has no advanced options. This air purifier has one control knob, 3 fan speeds, and a filter reset indicator. However, I would like to point out that the Blueair remembers the last speed used and switches on as soon as it gets power. This means that you can use this air purifier in combination with a smart plug.

This air purifier is an excellent choice if you are looking for a device for a larger room. It is a perfect choice if you have a considerable amount of dust in the room where you live or are plagued by pollen problems and similar situations. It fits perfectly in a living room, kitchen, large party room, or any other larger room.

Levoit LV-H134 – Great for Large Rooms Too

Levoit LV-H134 - Best Air Purifier
Levoit LV-H134 air purifier.

Levoit LV-H134 Highlights

  • The Levoit LV-H134 is a great air purifier that I tested in a 560 sq. ft. room. It improved the air quality by about 94%.
  • This air purifier is extremely quiet in sleep mode. The first and second speeds are bearable. This air purifier is one of the loudest air purifiers I have tested so far at maximum speed. At maximum speed, it produces a sound of around an incredible 70.3 dBA.
  • I like the motor, with only 49 watts of power, and the long-lasting replacement filters, which last an average of 6-8 months.
  • Levoit, like most devices, provides a 2-year warranty on this device.

The Levoit LV-H134 is another excellent air purifier designed for rooms up to 492 sq. ft. Like the Blueair 211+, I would recommend it for large rooms.

This air purifier uses a 3-stage filter system, including a pre-filter, a True HEPA filter, and an activated carbon filter. The filter is huge, cylindrical, and hollow in the middle.

I should mention that this is a very large air purifier and that you should think carefully about the space in a room before you buy it. The Levoit LV-H134 has a four-speed motor, and I particularly like that it has a sleep mode.

This air purifier also boasts many advanced options, among which I would highlight the air quality sensor, air quality indicator, and auto mode. I would recommend the Levoit LV-H134 for any large room such as a living room, master bedroom, basement, or similar. I would like to point out that the Levoit LV-H134 is ozone-free and entirely safe for use. So if you are looking for an air purifier for a large room but with a few more options, my recommendation is the Levoit LV-H134.

Levoit Core 300 – The Best Budget

Levoit Core 300 - Best Air Purifier

Levoit Core 300 Highlights

  • The Core 300 performed excellently in performance tests and improved air quality by about 93% in a 194 sq. ft. room.
  • The Levoit Core 300 is extremely quiet in sleep mode, producing a sound of only 40.7 dBA, and is also quiet at other speeds, except at max speed, which makes a sound of 64.9 dBA.
  • This air purifier uses a 45W motor. Replacement filters last on average 6-8 months but are affordable, which means that the Core 300 has affordable annual maintenance.
  • The Core 300 comes with a 2-year warranty.

The Core 300 is perhaps one of the most popular air purifiers that Levoit has launched. This device covers rooms up to 219 sq. ft. It is ideal for small rooms. It is affordable and accessible to maintain.

It uses a 3-stage filter, cylindrical in shape, hollow through the middle. I like the variety of replacement filter options in this model, so you can also purchase a pet allergy filter, a toxin absorber, or a mold bacteria filter.

The Core 300 has enough advanced options to benefit you in your daily use. The device has a timer, sleep mode, screen lock, display off, and filter reset indicator options.

I would recommend this air purifier to anyone looking for a small, cute and efficient air purifier that is also very affordable and won’t let you down. It is ideal for small spaces such as a small bedroom, office, small living room, small kitchen, etc.

  • The Blueair 411 Auto uses 3 speeds, has no sleep mode, and is slightly louder at top speed than I expected.

8 Best Air Purifiers – Video Review

It is hard to choose the best air purifier for your needs because your needs are different from other people’s needs. That is the main reason why there are so many kinds of air purifiers on the market. I hope this best air purifier buying guide will help you find the best air purifier for you.

Research of The Best Air Purifiers

Selecting an air purifier for a list requires a detailed analysis, using the device, performing all kinds of tests, assessing the brand’s reliability, the availability of replacement filters, and so on. We research and select the air purifiers to be tested based on the state of the market. Ideally, we would be able to review all the air purifiers currently available on the market. Still, we select devices based on various parameters since this is not the case.

Some of the air purifiers we have tested so far
Some of the air purifiers we have tested so far!

We often listen to suggestions from readers and viewers on the YT channel for air purifier reviews. So don’t hesitate to give your suggestions and comments, either on the YT videos or on the comments on the website.

How do we Test Air Purifiers?

Performance tests – I measure the performance of each device using a laser dust particle counter. The tool used is a Temtop particle counter, from which I read PM2.5, PM10, particulate, and AQI ratings and use this to compare how each air purifier performs in the tests. I place each air purifier in a room of specific dimensions, in front of which, of course, I measure the current air quality. After 60 minutes of operation at maximum speed, I measure the air quality in the room again and calculate by how much the air quality has improved.

Noise tests – this is an unavoidable test that I carry out on all devices. Basically, I test the loudness of the device at each speed separately and measure it with a unique tool. With its objective commentary on the motor’s performance, the noise test influences the assessment of the device’s noise. I say motor performance because it sometimes happens that an air purifier produces a moderate volume on a noise test, but the motor is so strange, it bursts or stutters, that it is impossible to listen to it, even though the volume is low.

Power consumption – I use a unique tool to measure the power consumption for each speed and then calculate and predict the monthly power consumption.

Smoke test – this is a unique test that sets Air Purifier First apart from other similar review sites. Basically, we put the air purifier in a glass box, which we then fill with smoke, turn the machine on and measure how long it takes the device to remove all the smoke from the box.

Best Air Purifiers - Smoke Box Tests Comparison
This image presents a smoke test comparison between four different air purifiers.

You can see more these tests in detail on the Air Purifier First YouTube channel.

Priceprice/quality ratio is perhaps one of the most important parameters, especially considering that many expensive air purifiers on the market are basically not of good quality and not worth the money. There are also many cheap air purifiers on the market that use low-quality filters that are also not worth it.

Operating costs – this is basically a conclusion we draw based on the price of replacement filters, the lifetime of replacement filters, and electricity consumption. This test determines whether the air purifier is suitable for maintenance annually.

Real-life conditions – To gather the best possible information and test air purifiers more accurately, I have sought help from some colleagues. So my brother helps me test air purifiers in the middle of pollen season, mainly because he is allergic to pollen. His comment means a lot to me; it is very thorough. Believe me, he feels the difference in air purifiers very well, and some devices help him a lot, some almost nothing.

Of course, there are tests in the kitchen, especially when cooking fish or other food in oil. I cannot imagine not using an air purifier in such situations. Of course, in addition to these real tests, I also measure tests with specialized tools.

In general, all the tests I do are objective. I am not biased toward any product or brand, which confirms why so many users trust the tests on Air Purifier First.

Our tests are not lab-based; we use real-life conditions that we believe are much better, more accurate, and more accurately reflect the device’s performance.

Types of Filters Found Inside Air Purifiers

Recently, there has been more and more innovation regarding air purifiers. Companies are trying to attract new users with various innovations, improve filtration quality, and position themselves as high as possible amongst very strong competition.

To be honest, I rely most on air purifiers that use True HEPA filters, so all the air purifiers on the list are equipped with True HEPA filters, except Blueair, which uses their innovative particulate filter, which has shown excellent performance, even better than some HEPA filters. The performance of HEPA filters is reflected in the ranking, as seen in the table below.

Best Air Purifier - Different Filter Types
I have placed a few different filters on the desk so you can compare them and see a difference.

In addition to the HEPA filters, most air purifiers have a pre-filter, which is very useful and basically serves to prevent any large particles of dust, hair, and the like from entering the primary filter (in most cases HEPA) and thus prolonging its life.

You will also find carbon filters in most air purifiers that are responsible for neutralizing VOCs. The EPA has a list of common sources of VOCs that can be found in a household that will be neutralized by an air purifier with a carbon filter:

  • Paints, paint strippers, and other solvents
  • Wood preservatives
  • Aerosol sprays
  • Cleaners and disinfectants
  • Moth repellents and air fresheners
  • Stored fuels and automotive products
  • Hobby accessories
  • Dry-cleaned clothing
  • Pesticides
  • Building materials and equipment
  • Office equipment such as copiers and printers, correction fluids, and carbonless copy paper
  • Graphics and craft materials, including adhesives and glues, permanent markers, and photographic solutions.

In addition to standard filtration methods, some air purifiers use ionizers. When the ionizer is switched on, a voltage is applied to a series of built-in needles, which generate electrons discharged into the air. When these electrons attach to air molecules, ions are formed. These negative ions are dispersed into the room. They bind to dust, pollen, cigarette smoke, and pet dander to form more massive particles more easily trapped by the air purifier. These particles can also be dropped on the floor to be vacuumed.

Finally, UV-C lights also serve the purpose of filtration and kill bacteria and viruses very effectively.

The most important thing is to ensure that every air purifier has at least a pre-filter, a True HEPA filter, and an activated carbon filter.

How Important Is Room Coverage?

To decide on any type of filtration, the next step you need to pay attention to is the device’s airflow. This is an essential step because if you buy a weak air purifier that cannot cover the room in which you intend to use it, it will not be effective enough.

When buying air purifiers, it is important to pay attention to the ACH, which stands for Air Changes Per Hour, which translated means that if the coverage of a room with an air purifier is 200 sq. ft. and if the ACH in that room for the same device is 2 ACH, then that device will clean the air 2 times per hour in a room of 200 sq. ft.

If you purchase an air purifier and determine the room’s size, always make sure that the ACH is at least 2, and ideally 4.8, which is the industry standard, and any air purifier that is AHAM verified is certified to this standard.

I would advise everyone to pay attention to the accuracy of the data, as many manufacturers claim that the air purifier is best for an “xxx” sq. ft. size room but do not specify how much ACH is in that room. In the reviews I do on the Air Purifier First website, I always list the room size where the air purifier has an ACH of 4.8 as the recommended room.

Can an Air Purifier Help With Wildfire Smoke?

Of course, it can. This is especially known to many air purifier users who live in California, where fires are a big problem, and from where many people have contacted me, both on YT and by email, for advice on which air purifier to choose for wildfire smoke.

The best air purifier for fighting fire smoke, which I very often suggest to people is the Winix 5500-2, whose pellet-based activated charcoal filter is exceptionally high in quality and effective in fighting smoke.

What About Air Purifiers With Washable Filters?

The thing about air purifiers with washable filters is that you don’t have to think about when you need to buy a replacement filter, whether replacement filters will be available, etc. Personally, I am happier with HEPA filters than with washable filters or similar filters that are currently available on the market.

Tried a few and made a list of the best air purifiers with washable filters. Some extremely high-quality machines on this list perform very well, as do air purifiers with HEPA filters.

Interestingly, all the air purifiers with washable filters I have tested so far are that, in addition to the main washable filter, they also have a predominantly carbon filter, which is not washable. This means that these air purifiers do not have 100% washable filters. So they are running away from the idea of a maintenance-free air purifier.

Why Should You Trust Us?

In 2016, I started the Air Purifier First project. Between then and now, I have tried many different air purifiers. Every year I take the tests to a higher level, inserting as much content as possible, tests and comparisons, and other content that can benefit potential customers.

The multitude of positive comments on the purchase recommendations proves that Air Purifier First’s recommendations are reliable and trustworthy. Many of the positive comments are publicly available on the YouTube platform and in the comments section of the website.

Furthermore, I am not biased by any of the producers, myself, or the assistants involved in the project. For the rest of you, if you haven’t already, I suggest you read in detail how we test air purifiers, why our tests are unique, and why our reviews are highly appreciated.

How to set an Air Purifier Like a Pro?

When it comes to air purifier settings, I recommend a few tips.

Best Location

Under no circumstances should you position the air purifier to block the airflow or place it in places where there is not enough air. In fact, it would be best to follow the above tips for placing the air purifier in different locations around the room until you decide which location suits you best.

Choose the Speed

Basically, air purifiers are most effective at maximum speed. Still, the problem is that they are usually too loud at maximum speed. It is very difficult to stay in a room where the air purifier runs at its strongest setting. It is, therefore, best to keep the air purifier at maximum speed for the first 15 minutes of use and then switch to another fan speed that is not too loud. This way, you’ll clean the air quality initially and keep it clean later by moving it to a lower speed.

Adjust the Air Quality Sensor 

Adjust the sensitivity of the air quality sensor to make the air purifier work more efficiently. In this list, you can adjust the sensor’s sensitivity with the Coway AP-1512HH and Levoit Core 400S.

Use the Smart App

Finally, I advise you to fully program the air purification mode via the Smart App if there is such an option. It is good to program to switch the device on or off if the air quality is above or below a set air quality limit. Extinguishing at night, switching to a higher speed if the air quality drops significantly, etc. All of this will allow for greater efficiency while at the same time reducing electricity consumption.

What About Other Good Air Purifiers on the Market?

In addition to the 8 best air purifiers, there are many other devices on the market that I would recommend buying.

Often, users are looking for air purifiers for specific situations, which means that sometimes it is possible that another air purifier not on this list may be better for a particular situation.

For this reason, I have compiled a list of the best air purifiers for specific situations that I believe will benefit many users.

The Competition

We have tested many air purifiers, some have made it to the best list, and some have not for different reasons. Below I will list some of the air purifiers we have tested so far and the reasons why we have removed them from the list of best air purifiers or why they are not on the current list.

Hamilton Beach TrueAir

The Hamilton Beach TrueAir is an air purifier with a washable filter, but not nearly as efficient as air purifiers with True HEPA filters. It is also extremely affordable and one of the cheapest devices out there.

Philips Series 800

The Philips Series 800 is a globally known air purifier. It is very reliable, performs well, and is an excellent buying option, but not that good to be on the list of the best air purifiers.

Levoit Core Mini

This is the smallest air purifier in the Levoit Core series, characteristic of its minimalism, simple controls, and Aroma Pad addition. The Levoit Core Mini is an interesting air purifier but not competitive enough to be listed in this guide.

Levoit LV-132

The Levoit LV-H132 was on the previous list as one of the best cheap air purifiers you can buy. I should mention that this is an old model and that many newer, better, and more efficient air purifiers have been released in a similar price range.

GermGuardian AC4825

The GermGuardian AC4825 is an excellent air purifier that has performed very well in all tests. However, one of the most popular air purifiers on the market has been taken off the list because we have tested many better air purifiers after this model, which have easily replaced it.


Overall, the Ikea FÖRNUFTIG is an affordable air purifier that I am generally happy with. But the lack of a True HEPA filter is something I see as a weakness of this model.


The PARTU BS-08 is a decent air purifier that performed well on all tests. It is characterized by an interesting night light. However, it is often out of stock, as are replacement filters.

Levoit Vital 100

The Levoit Vital 100 is another fantastic air purifier from Levoit. Excellent performance, quality filters, and ease of use make this air purifier a perfect choice for purchase.

Mediify MA-25

The Medify MA-25 is characterized by its True HEPA dual filter. This makes it a very efficient device and a bit more expensive to maintain as you need to replace two filters instead of one.

Xiaomi Mi 3H

The Xiaomi Mi 3H is one of the best smart devices I’ve tested, and it also performed well in all tests. However, sometimes filters are not available for this air purifier, which can be annoying when you need them.

Honeywell HPA100

The Honeywell HPA100 is a small air purifier, very popular but with a somewhat industrial design. However, this does not change the fact that it is very reliable and efficient.

Levoit Vista 200

The Levoit Vista 200 is a decent air purifier, very nicely designed, and easily fits into any environment. However, many other Levoit air purifiers are also nicely designed but with slightly better performance and scores on tests.

Hathaspace HSP001

The Hathaspace HSP001 is a very powerful air purifier equipped with a 5-in-1 filter that is responsible for its outstanding performance. What puts me off with this model is that it does not have a filter reset indicator.

Aura Air

The Aura Air is an innovative air purifier with features that are not usual for this device. It is designed for wall mounting, which may be a limitation for some users.

Molekule Air

The Molekule Air is definitely the air purifier around which most of the dust is raised on the market. Basically, this air purifier does its job, but not as good as it should be given the price.

TruSens Z-1000

The TruSens Z1000 is a small, high-quality air purifier with a distinctive, modern design that fits into almost any environment. My complaint is that this model does not have a True HEPA filter.

GermGuardian AC4200W

The GermGuardian AC4200W is one small, very decent air purifier. Still, there are simply many better devices on the market in a similar price range.

Blueair 411

The Blueair 411 is a very high-quality and popular air purifier. To be honest, I was hesitant whether to include this model or the Blueair 411 Auto in the buying guide. The air quality sensor made the decision to fall on the 411 Auto.

Smartmi P1

The Smartmi P1 is another smart air purifier with a luxurious look, good performance, and can be connected to HomeKit.

Airdog X3

The Airdog X3 is an interesting air purifier that uses washable filters. It has an excellent performance, even though it uses washable filters. I don’t like that it has a replacement carbon filter, which ruins the idea of a 100% washable filter air purifier.

FAQ on Best Air Purifiers

Do air purifiers really work?

Yes, they work! Air purifiers are proven to work and improve the air quality in the rooms they are used in.

What is a HEPA filter?

A HEPA filter, also known as a High-Efficiency Particulate Absorption filter or High-Efficiency Particulate Arrestancefilter, is the standard of air filter performance. Filters that meet the HEPA standard must meet certain efficiency levels.

Why are some air purifiers not listed?

Quite simply, this is a list of the best air purifiers I have tested so far. The reason why an air purifier is not on the list but may have a good predisposition to be on the list is that I have not yet tested that device.

Are air purifiers a waste of money?

No. Air purifiers are not a waste of money, and there are several ways to confirm this before buying one, and I recommend checking out the detailed tests published on the Air Purifier First website or YouTube channel and reading the hundreds of positive comments on the YT channel.

Do air purifiers increase or decrease oxygen in a room?

Air purifiers do not reduce the amount of oxygen in the air.

Do I use any of the air purifiers daily?

Yes, of course. As I have received this question from many users, it is time to answer. I use different air purifiers during the month. Mostly the devices I test. However, lately, I have found the Levoit Core 400S to be the air purifier that suits me best. I use it in the living room. Additionally, I use the Core 200S in the bedroom because I have a small bedroom where this model is sufficient.

Final Thoughts

I have presented a list of the best air purifiers that you can currently buy on the market. These are really top-of-the-range devices, top quality, performance, and worth buying.
