Coway
Portable HEPA air purifiers spanning bedroom-scale units through large-room whole-space filtration.
What they're known for
A mature air-purifier platform with published room coverage, CADR, noise, filter, and sensor data across a broad range of residential sizes.
Coway’s Airmega line covers compact bedroom purifiers through large-room systems, using combinations of washable prefilters, HEPA media, activated carbon, particle sensors, and automatic fan control. Current models range from small-space units to Airmega 350 and 450 systems rated for much larger open areas, while S-model variants add app and voice connectivity. The useful distinction is the depth of published specifications: room coverage, CADR, noise, power draw, filter life, and operating modes can be compared before choosing a unit.
