MILA AIR 3 Critter Cuddler, $297: MILA has made seven custom filters designed specifically for expectant mothers, allergies, pet owners, etc. Adding Mila’s built-in sensors and easy-to-use application dashboard, as well as its wood-fixed modern box design, Mila is a straight-forward favorite. The more I cover the air purifier, Great quiet think. Smaller models tend to run loudly on their highest settings. Mira is not as quiet as I hoped. Mila hit 70 dB on my consumer decibel reader while on Full Blast. At 447 Cadr M3/hr, MILA performed well in an average US 200 square feet bedroom. You can run MILA in the highest setting in a 400 square foot room of five air exchanges recommended by the CDC, but it’s a noisier air purifier. I ran the Mila in my son’s 200 square foot bedroom, which automatically set up correctly to the air quality of the room. Although Mila gets its outdoor AQI (Air Quality Index) from Purpleair, it seems that my PurplePleair outdoor monitor cannot be found.
Briiv 2 Pro Air Filt, £399: Briiv’s 2 Pro Air Filters have great requirements in the small package. At 2.5 pounds at the Briiv 2 Pro air filter, it is the smallest air purifier I’ve ever tested, although it’s far from the cheapest. The company claims a Briiv equals a peculiar 3,043 houseplants and uses an AI-powered air quality sensor. I don’t usually review air purifiers that are not certified by carbs (California Air Resources Commission), but I’m interested in Briiv. That said, the actual space that the Briiv 2 Pro can clean is very small. I went into the size of the restaurant, went into Briiv’s website calculator, with 9 feet ceilings at 20 feet long and 11 feet wide, and the room calculator concluded that I needed two Briivs to effectively clean my restaurant. The calculator seems to contradict Briiv’s claim that Briiv 2 will effectively improve air quality in 794 square feet of living space in just 11 minutes. I currently have Briiv 2 in my kitchen and because of my cooking, its indicator light turns red for the first time and I can’t get the fan to activate. I ended up exploding it all over with Briiv’s a bit clumsy app. I played the app and since then my Briiv fans have automatically adjusted to make the air poor without my help. It looks cool, too.

Puroair 240 HEPA Air Purifier for $159: The 9-inch-high PuroAir 240 is a tiny air purifier. Like many smaller desktop models, it’s also big. It may work in tight spaces, such as rooms of about 100 to 150 square feet. Like most air purifiers we review at Wired, it is certified or certified by the California Air Resources Council. I found its filter size too small to effectively clean room of average size. And, while I will still review smaller air purifiers, there are larger, quieter models on the market that cost relatively much and have a larger air exchange in large rooms. Puroair’s indicator light is adjusted by the internal sensor of 240 and is green, acceptable, yellow, moderately red, and poor air quality. Sometimes I find that the light on the indicator light is very thin and difficult to see. 240 has automatic or manual mode, timer, sublock and filter replacement light. It also features three-stage filters including tightly woven HEPA 14, activated carbon and front filter. Finally, the black plastic of the 240s attracted a lot of fingerprints.
Others We Tested
Coway Airmega 250 costs $313: The Airmega 250 covers a considerable area, but cleans a 930 square foot room twice an hour. That’s why I put it in the middle of the first floor of my home to clean the air in the kitchen and living room. Every time we cook, the Smart Mode automatically detects unhealthy particles in the air and raises the power of the fan. Recently, when I have someone patched some plasterboard in a mud room, it did the same. (This mode is used with the help of PM10 and PM2.5 particle sensors.) The highest setting for the fan is not That Loud – I measured it at 60 decibels. If you want to remain silent, use sleep mode. You can get the usual controls such as timer functions and replacement indicators for filters. Talking about, the Airmega 250 uses a real HEPA filter that needs to be replaced every six to 12 months. Combined with a washable front filter that you should keep clean and activated carbon filters every two weeks, the air purifier can lower 99.999% of superfixed particles to 0.01 microns, or Coway says. It’s very easy to remove these filters to clean and exchange them. The entire system is about 21 pounds, so you can move it easily. Coway offers a three-year warranty. The Coway Airmega 250 is the same model, but has Wi-Fi capabilities, so you can control it through the app and see more details. The last thing I need is another app, but maybe you don’t mind. – Julian Chokkattu
Coway Airmega icon for $469:Coway continues to make some pretty air purifiers, which, as you might notice in this guide, has something to do with the Airmega icon. It looks like a terminal table, so I put it next to the sofa. The star of the show is the Qi wireless charging pad, so when I sit down, I just put my phone directly on the purifier to get it charged. Any phone with wireless charging support will work, although you may need to remove the phone case. Like all coway purifiers, it is powerful – it cleans the air in a space of up to 649 square feet – controlled and easy to clean. This version is Wi-Fi and voice control enabled. –Medea Giordano
How to buy an air purifier
How do busy shoppers find the right size purifier to clean their room? The Centers for Disease Control recommends that a measure called ACH should target five air exchanges per hour. When viewing the air purifier, view cubic feet per minute in the airflow in the lowest settings. When measuring a cubic lens for a room, you need the room area time to be height. Imagine a foot of styrofoam. How many cubes can you install?
Anyone who buys an air purifier will also need to look for two acronyms and terms. First, look for carbohydrate certification, which means that the air purifiers pass the strict standards of the California Air Resources Commission. Next, check the filter type. Below, we break down the difference. Also, don’t forget to open the filter! Realize that you have used a plastic-packed HEPA filter to run an air purifier with a special horror.
HEPA filter: This is a highly efficient particulate gas filter that removes at least 99.97% of dust, mold, pollen, bacteria and airborne particles up to 0.3 microns. This is a great option for those suffering from allergies or respiratory problems as it can help remove air particles that cause symptoms such as sneezing, sore throat, difficulty breathing, coughing, and more. However, it is worth noting that the HEPA filter does not remove volatile organic compounds from the air like the activated carbon filter. But these are usually paired with carbon filters.
Activated Carbon: Activated charcoal filters (also known as activated charcoal) are very effective because they are very porous and have a large surface area that allows the filter to absorb gas pollutants, odors and VOC. They are best suited to remove smoke, smoke and chemicals from the air. However, depending on the environment, these filters must be replaced more frequently. For example, if you are in an area where there is a wildfire and the air purifier works more intensely than usual, it is more important to replace the saturated filter to avoid the toxic gases coming back into the air.
Washable air filter: Some of the air purifiers we list in this guide come with a washable prefilter in addition to HEPA and/or activated carbon filters, which are usually what you will find normally. These are the most cost-effective because you don’t have to buy new products every time you need to change the filter. Simply remove it, scrub it with soap and water, and dry it.
UV-C Disinfectant Filter: UV filters use UV to kill viruses, parasites, molds, and bacteria. They cannot remove particles, VOC or gas pollutants from the air, so they can only be completely effective only when used in combination with HEPA filters. According to the U.S. Environmental Protection Agency, UV light without proper lamp coatings has the potential to emit ozone. We recommend that you check this list from the Air Purifiers of the Home Equipment Manufacturers Association, which emit almost no ozone.
How to check your air quality
Many large states and cities need to report local outdoor air quality indexes established by the EPA and measure the concentration of major air pollutants such as ozone and carbon monoxide regulated by the Clean Air Act. We like AirCare (iOS, Android), but your state or county may have more local apps.
To check if your indoor air quality is stacked, in addition to pollutants and particulate matter, consumer monitoring ($90) and Airthings View ($300) are also measured in addition to pollutants and particulate matters. M10 also measures formaldehyde, a harmful chemical that is the deviation of common household items such as particleboard furniture and certain foam mattresses. Need more information?

We do not recommend air purifiers
The price for IKEA Starkvind is $150: IKEA’s Starkvind air purifier will be launched in 2021. It is stylish and relatively cheap, and you can choose to add a carbon filter to gases such as benzene. It can be purchased on your own or built into a wooden table, but it is worth noting that the stark time took me an hour to assemble. While carbohydrate certified, which means it passes strict standards from the California Air Resources Commission, there is no HEPA filter. I thought I had an early version made for the media, so I went to the local IKEA. I bought a förnuftig whose manual lists the filter as HEPA. It’s not. We contacted the company; at the time of publication, IKEA said it was still routing the issues to the appropriate team. The question remains: If you are buying an air purifier, why not buy HEPA? – Lisa Wood Shapiro
dyson purifier humidification + cool formeldahyde priced at $1,000: Dyson’s humidification + cool formaldehyde reminds me of those three-in-one devices, which are toasters, coffee machines and egg-cooked amalgam. But if you are buying an air purifier that eliminates gases, I would choose to remove formaldehyde, a known cancer. My comment unit can never oscillate, but it should be done. (I tried troubleshooting through the manual, but the more features the project has, the errors are likely.) It also has a two-year warranty, which seems short. – Lisa Wood Shapiro
Moreto Air Purifiers cost $100: This carbohydrate certified purifier caught our attention earlier this year. With a CADR of 200 cubic feet per minute, Moreto is not only more powerful than most other purifiers at their price point, but also has all the features of the high-end model, including the PM 2.5 sensor and light indicator, as well as smart features through the Havaworks app. However, during testing, even though I burned the fragrance in the room to raise the level to 500s, the fan never raised the speed to compensate for higher PM 2.5 levels. Although the machine is set to auto mode in both the application and the machine itself, it persists, plus I clean the sensor and reset the device by unplugging it. Regardless, even if this feature works fine, Moreto offers a weird range for the acceptable PM 2.5 levels – the ring light indicator continues to glow green (“good”) until 75 pm 2.5, which is 15 times that of the World Health Organization (WHO) – requiring a level of 5 micrograms per cubic meter. – Kat Merck
