Coway: an upgraded smart air purifier

Air purifiers have come a long way and Coway leads the pack with an all-new smart air purifier called the Coway Airmega 400. You’ll get the reliability of HEPA, a washable, active carbon filter that reduces volatile organic compounds and odors by 99 percent.

This Coway comes with smart features not found in other brands. With Smart Mode, the Airmega automatically adjusts the fan speeds based on current air quality. That means it’s more energy efficient than your old, dumb air purifier. There’s also an Eco Mode that turns off the unit after 30 minutes to conserve energy and automatically kicks back on when air pollution is detected.
