It’s definitelywintertime, so if you’re chilly and sniffly this week, we found a small, easy-to-handle air purifier that not only acts as a heater, but also works as a cool-air fan. In other words, this baby is a year-round appliance you won’t have to stow away as the seasons change.

This Dyson Purifier Hot+Cool air purifier is designed for large room, able to draw in pollutants all around it then project 76 gallons of air per second throughout the space. It uses a HEPA H13 fully sealed filter. And it’s not just the filter that meets the standard, but the whole machine —ensuring what goes inside, stays inside.

With thoughtful controls and an attractive design, Coway’s new Airmega 350 is one of the best air purifiers we’ve tested.

Spring is just around the corner, and reviewers call this investment a “game-changer” for their severe seasonal allergies.
