🔊 Coway Air Purifier Noise Levels — Decibel Comparison
See what Coway air purifier noise levels actually sound like.
Coway makes some of the best-rated air purifiers in the US, including the legendary AP-1512HH Mighty. Noise performance is generally excellent — Coway purifiers are known for being quieter than competitors at similar CADR levels.
The AP-1512HH is remarkably quiet at 24.4 dB on its lowest setting, making it one of the quietest purifiers available. The Airmega 250 uses a dual-intake design that reduces turbulence noise. Even the large Airmega 400 stays relatively quiet for its size.
Coway uses a 3-speed system (low, medium, high) plus eco mode and auto mode. On auto, the purifier runs at low speed when air quality is good, ramping up only when needed.
