Review on 🌬️ Fil-fresh 2-Pack AP-1512HH Air Purifier Filter Compatible with Coway, includes 8 Carbon Filters - Part# 3304899 by Vinay Mickel

This is about half the price of the Coway. But they are not of the same quality. The box rim is not as tight as Coway, which also uses filter material for the rims. The filter material is thinner. The same number of folds, but you notice that the thickness of the material is much less. Not so "chubby". More like a coffee filter. When using filters, the thickness of the material is of great importance. A thicker medium will hold larger particles before it clogs. The Nispira brand that I bought shortly before is almost indistinguishable from OEM and is priced somewhere between Coway and them. Although they are more expensive I find them cheaper and will probably buy Nispira in the future.
