Best praise vs top criticism for Coway Airmega 400S

Best Praise
+6 pts
Coway purifiers are top notch. i have an AirMega 400 model in the room where we keep our cat litter boxes. it's built like a tank and after a year, it still showed the filters at maybe 75% remaining. i replaced them anyway, as i know the carbon pellets were spent without a doubt, and wanted to combat litter box smells... but the filters were still in fine shape. Coway filters are like $80, but i found a review / test of third-party filters that didn't have any appreciable difference for $30. they make a bunch of different sized purifiers for different room sizes, so see what suits your sit.

This is infuriating. I bought the 400 thinking it would be the best option to keep the air clean for my baby and now I come to find out that I could possibly be doing more harm then good? Im trying really hard to remain calm right now.

I have two 200s with ionization. I just leave that feature deactivated. They are very good purifiers otherwise.

I bought knockoff filters for another levoit I have and they don’t fully seal around the base and smell bad
