Within 30 minutes, the Coway AP-1512HH Mighty reduced heavy smoke pollution in a 135-square-foot, 1,215-cubic-foot New York office by as much as 98.9%. In past tests, it performed equally well in a 200-square-foot, 1,600-cubic-foot New York City bedroom. And when we tested it during ongoing smoke conditions in a vast Los Angeles conference room of nearly 10,000 cubic feet—more than twice as large as the Coway Mighty’s specs would seemingly allow—it cut particulate pollution by almost 70% in an hour. It’s a great value, at an up-front price often under $200 (and about $470 over five years, factoring in electricity and replacement filters). The Mighty’s compact form, quiet operation, and ability to shut off its display lights make it especially well suited to bedrooms. In long-term use, we’ve repeatedly confirmed it works like new even with filters used continuously for a year or more.

Coway Airmega 200M

Coway Airmega 200M

Different look, same great performance

The 200M and the Mighty are virtually identical in performance, but the 200M has an appearance that you may prefer, and it’s a good alternative if you find it at a lower price.

The Coway Airmega 200M is made by the same company as the AP-1512HH Mighty and is virtually identical to that model in every important respect, namely the controls, noise, and performance. Their filters and even their faceplates are interchangeable. And like the Mighty, the Airmega 200M has a display-shutoff feature that lets you dim its lights, something we value highly for bedroom use. The Airmega 200M has a square grille rather than a round one—but that’s the only major physical difference. If you prefer the Airmega 200M’s looks or if you find it at a better price, we recommend it just as highly.

Blueair Blue Pure 211+

Blueair Blue Pure 211+

A stellar performer for larger rooms

The Blue Pure 211+ aced our tests, and its ability to move extremely high volumes of air make it our pick for large spaces.

Buying Options

$300 from Best Buy
$286 from Amazon

The Blueair Blue Pure 211+ is our choice among air purifiers for large spaces of up to 650 square feet, especially spaces with open floor plans or high ceilings. With the ability to filter more air per hour than our top pick, the Coway Mighty, it works faster to achieve and maintain low particulate levels in such challenging rooms. The up-front price and running costs of the Blue Pure 211+ are much higher than those of the Coway Mighty (totaling about $1,150 over five years), but that’s comparable to most other large-space purifiers we’ve looked at. It was an exceptional performer in our testing, and it’s quiet and attractive to boot. All that said, unless you really need to clean a particularly large space, the quieter, smaller, and more affordable Coway Mighty is usually a better option.

Small, effective, and attractive

In a small bedroom, dorm room, or office, the compact and affordable Levoit Core 300 performs extremely well and looks great.

If you need to clean the air in a space of around 200 square feet, the Levoit Core 300 is a solid and inexpensive purifier. It was impressive in our tests, reducing particulates by more than 97% on its high setting in 30 minutes in a 135-square-foot New York City office. On medium, it reduced them by more than 92%. It’s attractive and compact, measuring just 14½ inches tall and 8½ inches in diameter, and its display-shutoff feature means it won’t interrupt sleep with bright lights. At around $100 to purchase, it’s also the cheapest up front of all our picks. But it’s not terribly energy efficient: Running it 24/7 on medium will consume about $300 of electricity over five years, and seven new filters in that period will cost $180, making it slightly more expensive than the Coway Mighty long term. And it doesn’t keep pace with the Coway or the Blue Pure 211+ in larger rooms.

Austin Air HealthMate HM400

Austin Air HealthMate HM400

For odors and chemical sensitivity

This model’s HEPA filter removes particulates (like pollen and smoke) from the air, and its second filter efficiently removes odors and VOC gases—an ability many purifiers lack.

*At the time of publishing, the price was $595.

If your environment has high levels of both particulates and volatile organic compounds (VOCs, or more broadly, odors), we recommend the Austin Air HealthMate HM400. Its massive 15-pound VOC filter bested all others we tested by a wide margin, and its HEPA filter offered excellent performance on particulates. The HealthMate’s performance comes at a price, however: Costing about $500 to $600 up front and averaging around $1,200 for five years of use, it’s the most expensive machine we recommend. You could buy and run three Coway AP-1512HH Mighty purifiers for about the same cost, and if particulates are your main concern, doing that instead will let you remove particulates from more rooms and a larger overall area.
