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

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.

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