Which Air Purifier is the Best Choice for You?

The best air purifier you can buy today is the Coway AP-1512 HH Mighty. It has a PureZone True Hepa 3 in 1 Air Purifier, which is capable of reducing particles by 0.3 microns at 18.0% (ambient) and 26.4% (clean) in Auto mode. In Silent mode, it reduces 0.3 micron particles by 6.5% (ambient) and 7.2% (clean). In Dark plus Auto mode, with its primary PECO purification system turned off and its fan at the equivalent of a medium setting, it reduces them by 21.3% (ambient) and 18.0% (clean).

After careful testing and consideration, these are the best air purifier options according to our research. Any of the air purifiers below should improve indoor air quality, filter out smoke and particles in the air, and at the same time provide fresh air. The Coway HEPA air purifier is one of the best air purifiers with one of the most adventurous looks for a medium-sized room. The Blueair Blue Pure 411 is a simple and straightforward purifier with a smart design and a good investment for a 160 square foot room, making it the best overall air purifier for small rooms.

The Sharp air purifier doesn't offer as much cleaning power at almost double the price. If you have the money and want a super-powered air purifier, or if you prefer a purifier to cover your entire house than buy one for each room, the Coway Airmega 400 could be the best air purifier for you. This thing costs a dime, but you get 1,560 square foot air cleaning coverage. It's also important to note that many of the best air purifier models have been going in and out of stock in recent months due to high demand during the pandemic and in the midst of wildfires.

The Levoit air purifier is a Good Housekeeping seal holder, thanks to its combination of value, performance and intelligent design. It has three-stage filtration, which includes a true HEPA filter that helps capture even the smallest airborne contaminants in rooms up to approximately 400 square feet. It also has a built-in precision laser sensor that accurately monitors particles in the room and automatically adjusts fan speeds as needed. The purifier is incredibly quiet, working at only 24 dB, which you will appreciate if it is placed in your bedroom.

When choosing an air purifier, it's important to consider power for price (i.e., the higher the CADR and the lower the price, the better). Secondly, look at additional cleaning modes, usefulness of controls, overall design and noise level. The best air purifier looks elegant enough to fit modern decor, can work as desired with minimal manipulation, and can clean the air thoroughly and quietly. No air purifier can do anything against allergens, bacteria or viruses that have settled on furniture or other surfaces.

As mentioned above, transmission of the virus usually occurs through close contact in homes, which means that an air purifier probably won't protect you if someone in your household becomes ill. When looking for an air purifier, identify brands that have performed well and proven to be reliable through more than a decade of testing at Good Housekeeping Institute. Consider CADR numbers to determine how many cubic feet per minute of perfectly pure air a purifier can produce at its maximum configuration. Lastly, factor in intelligent capabilities such as an app that allows you to monitor air quality in real time, view filter life and set schedules.
