10-06-2025I finally installed one of the HEPA filters in my Coway after using a couple of the carbon odor filters. The odor filters seem just fine - I cant discern any difference from the original filter. However the HEPA filter causes my Coway to be significantly noisier than the original filter. With the original filter, the lowest setting is truly whisper quiet - basically silent in the room, barely audible within a couple feet. The Coway is no longer silent with the Fil-fresh replacement. Its still quiet, but theres a much more audible white-noise whoosh that you can clearly hear anywhere in the room. And at the higher settings, its significantly noisier. Besides the noise, two concerns with what must be higher resistance - its reducing airflow performance, and its putting more strain on the motor which could affect its lifespan. Ill probably just pony up for the OEM filters next time.
