Coway Airmega 400

If you'd prefer have one purifier that covers your entire house rather than one for each room, Coway's Airmega 400 might be the purifier for you. This gadget is pricey at $377, but you get 1,560 square feet of air cleaning coverage.

The Airmega has a lot of features, including a real-time air quality monitor, many fan speed settings (the highest of which is surprisingly quiet), smart settings that alter fan speed based on air quality, and a variety of timers. It also weighs over 25 pounds, making it larger than many competitors.

Most homes would be better served by one or two smaller Coway or Honeywell air purifiers, but if you have a specific requirement for a large amount of coverage, the Airmega could be the correct choice.

Price: $570.21
