The fan's speed level and the unit model affect the noise level of the air purifier. Different Airmega model units vary in fan strength and unit weight. Shaking also causes some noise, and minor unit shaking is natural, depending on the fan speed.

The air purifier's distance from other appliances and furniture can also affect the unit's noise level. The air purifier unit needs enough space to function normally. If you think the noise is not normal, you may reach out to the Coway Support Center for further assistance.
