Your first place to start when buying an air purifier

The Vista 200 is a compact air purifier that uses a low-power motor. Its three-stage filtration technology effectively cleans the air in small spaces.

The Blueair 511i Max is a compact, elegant, and powerful air purifier that's equipped with plenty of smart features.

The Airdog X3 doesn't require filter replacements, offers plenty of smart features, and performs exceptionally well in our tests.

I compared two small air purifiers: the Winix A231 and Philips 800. Neither has smart features, but both are highly efficient—yet only one comes out on top.

Today, I'll compare the Levoit Core 400S and Levoit LV-H134 air purifiers to determine which one is the better buy.

Which air purifier is better: the Levoit Vital 200S or Winix 5500-2? I compared performance, noise, and maintenance to make the right choice.
