Coway Air Purifier Airmega 200M True HEPA with 361 sq. ft. Coverage in Black

Noisy but effective. Cabin life is great especially a roaring fireplace but even a well sealed firebox can create a lot of airborne particulates. Micro particles of wood ash wafting around meant dusting was a frequent chore. This thing really works. It quietly cycles on and off under normal conditions but goes into overdrive within seconds when the firebox is opened to clean out the ash. Sensing the particles from 15ft away. It does get pretty loud then drowning out normal conversation for 20-30 seconds. But when there's no wood ash or dust it stays quiet. After 4 months of use I can say its worth the purchase and our lungs are very appreciative.

I bought this to keep the air clean during California wildfire season. It does the job handily in my room, which is about 300 sq ft. (and also very dusty because it is an old house and my room is a converted porch.) Each of my roommates also has one of these air purifiers, so we are all now fans (no pun intended). The setup directions were clear and the setup itself was not challenging. It is extremely easy to see how to operate the device and to understand what it is telling you about air quality.
