Blueair's Blue Pure 311i Max is a HEPA air purifier aimed at smoke, allergens, and other particles. If you suffer from seasonal allergies or live in an area at risk of smoke from wildfire season (aka most of America), this air purifier could be a good investment toward cleaner air.

The Blue Pure 311i Max clears pollutants from the air and circulates clean, fresh-smelling air (I live in a home with two of them). I've encountered other air purifiers that can smell like plastic for the first few weeks. This one doesn't.

The 311i Max has a wraparound prefilter that traps pet fur and large particles before they clog the internal HEPA filter. This wraparound is simple to clean, helping to extend filter life.

Inside, an activated carbon filter provides even more filtration power and helps eliminate smells and cooking odor. The filter isn't designed to trap VOCs, gas, or other chemicals — at least, not that effectively (most air purifiers aimed at these types of pollutants will generally cost a lot more).

Whether for tree allergies, cat dander relief, or to prep for a smoky summer, the Blue Pure is a great air purifier that will benefit all sorts of homes. Plus, it's controlled via a handy app.
