Air purifiers are one of those under-the-radar household items that you think you can live without, but once you have one you can never go back. These mighty machines do a lot of work: they work to clear the air of allergens, pet dander, germs and even odors. And couldn't we all stand to breathe air that's just a little bit cleaner? We've rounded up our favorites from all price points and sizes to help you find the right purifier for your needs.


How This Works

Every week we research new product categories and bring our final picks into the office, where we haggle and decide which ones make the final list. Everything is based on quality, appearance and price. These are what we could choose for our own home.


Our Top Pick

Levoit Compact HEPA Air Purifier

I'm a huge air purifier fan, have owned many, and always keep one in my bedroom where you breathe the air the most. Personally, I believe that most purifiers will do a perfectly good job, and the trick is to find one that is quiet and that has the right shape for your home and a price you can afford. While I love all the purifiers we looked at this week - they all rock in their own way - we chose this small unit because it was the most practical for our readers and could work in many rooms. Aesthetically chic, well priced and smaller in scale, this year's prize goes to the Levoit Compact.

Coway Mighty Air Purifier

Coway's tagline for this purifier is "minimum space, maximum efficiency," which is fitting for this quiet little machine that boasts 4-stage filtration and a Vital ION system that deactivates bacteria in the air. The Coway is very hands-off as well, with an eco mode that turns the fan off once no pollution is detected for 30 minutes and automatic speed adjustment depending on the air quality levels.

Blue Pure 121 Air Purifier

Our top pick in the mid-priced category, the Blue Pure family is the energy-efficient and ultra-quiet air purifier from the experts over at Blueair.

All the Blue Pure purifiers are Energy Star-certified for low energy consumption, and the 360° air intake ensures maximum Clean Air Delivery Rate.

RabbitAir MinusA2 Ultra Quiet Air Purifier

Our top pick on the high-end range, this purifier is the latest model from the pros at RabbitAir. Sleek and sturdy, it kind of looks like a TV — and can be wall-mounted like one as well.

What is a HEPA Filter (and Why Should I Care)?

In the air filter world, the HEPA standard has evolved as the go-to "good enough" quality level. Developed originally during WWII by the Atomic Energy Commission's Manhattan Project to clean radiation out of the air, the design evolved over a number of years into an affordable, mass-produced paper filter system that could be integrated into purifiers, vacuums and other units for commercial and residential use.

To qualify as HEPA by US government standards, an air filter must remove (from the air that passes through) 99.97% of particles that have a size of 0.3 µm.

"HEPA: High-efficiency particulate arrestance or HEPA is a type of air filter. Filters meeting the HEPA standard have many applications, including use in medical facilities, automobiles, aircraft and homes. The filter must satisfy certain standards of efficiency such as those set by the United States Department of Energy (DOE)." via Wikipedia
