Fil-fresh Airmega AP-1512HH Air Purifier Replacement Filter for Coway, 2-Pack

I like that they provided two types of filters. One that you change every three months and the one you change every six months.

Make certain that your air cleaner is listed as fitting this by the manufacture. I went by reviews that said it fit my blue large room air cleaner. It did not. I mistakenly waited until after the 30 days to place them in the machine at which point in time I discovered they did not fit. This is one of those lessons were you say live and learn hopefully help someone else.

Exactly what I needed.
