Answer This Question

A:  Thank you for your interest in our Permanant Washable Filters- But our units are designed for HVAC systems not fireplaces - We have not heard of any filters designed for Fireplaces- i would think it would be a fire hazard. In any event if you are looking for a HVAC - Furnace/AC Filter then please purchase ours - Thank You

            I made a mistake, I needed a solid filter, I will return this one, but have already ordered the solid unit. MERV 8 and washable is astounding! I will likely add 2 more soon.

            It does not fit firmly into the air vent. And when you gotta take it down because it’s loose, it falls right out of my vent in the ceiling.
