The Best Air Purifiers

  • Winix 5500-2 Air Cleaner with PlasmaWave Technology – High-End Features
  • Coway AP-1512HH Mighty Air Purifier – Long-Term Savings

Intuitive controls and sensors
Above all else, Winix stands out for its lineup of features. Its completely digital panel lets you control the purifier’s speed or enable PlasmaWave Technology (which, when activated, claims to “instantly neutralize airborne viruses, bacteria, chemical vapors, odors, and gases”). The simplicity of this digital panel extends to its sensors: The Winix’s glowing LED lights shift from blue to red the more polluted the air.

It’s not just looks, though; the Winix is also packed with features that make life simpler if you don’t want to constantly monitor your machine. Specifically, a built-in air quality sensor automatically runs the fan at its lowest when the air quality is good — a nice touch for your peace of mind and for saving power. Other models like the Blueair air purifier came with some controls and sensors, but they weren’t nearly as robust as those on the Winix. Simple digital design and a full breadth of automatic features won us over.

Hassle-free filter replacement
Popping the hood of the Winix was easy. The cover uses magnets to snap in and out of place, and each filter locks inside the next — there’s no question where each piece should be when replacing the filters. By comparison, the Coway is much flimsier, and it takes a couple of tries to put the front and pre-filter back on after you remove them.

More cost-effective than similar models
Air purifiers can get expensive, often topping the $600 mark. That’s why the Winix, at less than $200, is so impressive: It’s powerful enough to cover 360 square feet and comes with features like air quality sensors and Auto settings that are found on more high-end air purifiers. If you’re looking for a powerful air purifier that comes with all the bells and whistles (but not with a high price tag), the Winix is worth considering.

Not as powerful as some competitors
Admittedly, there are more powerful air purifiers on the market. The Winix U450, for example, has higher CADR ratings, covering an additional 100 square feet. However, this 100 square feet comes at a cost: The U450 model is double the price of the 5500-2. The Winix 5500-2 may not cut it if you have an unusually large room, but its features and affordability still push it to the top of the lineup. If you’re concerned about that additional 100 feet of coverage, you may be better off purchasing two 5500-2 units for features and cost-savings alone.
