What Our Customers Think

Easy to install and maintain. Filtering ability is superior over the "store-bought" types. The support frame is very sturdy and the exact size for my AC system.

Peter H.

Best filter ever!!! Been using these filters for 22 yrs. To get an AC in FL to hold up for 21 yrs is unheard of. I attribute it to these filters for keeping the inside handler cleaner than any other.

Georgene F.

These are the best filters I've ever used. They capture so much dirt and dust that would have ended up in my family's lungs. The customer service is fantastic. I will never buy furnace filters any place else.

Jim W.

We've been using these filters for 10 yrs since we found out the house we moved into had some mold issues (since resolved) and that my husband was getting sick from the mold spores. These filters really do a good job of cleaning the air! So much better than the store-bought "cheapy" ones. We'll never go back, highly recommended!

Andrea R.

My husband and I had these filters when we bought our house. (leftovers) We made the MISTAKE of buying CHEAPER ones the next time around. Boy did we suffer. we immediately switched back. The Biosponge filters definitely work better and make the air cleaner. We are now loyal customers and will NEVER go back to the cheapo ones. Thank you so much!!!!

Jennifer M.

I've been using these filters for 10+ years, so I figured this commands a review for just being a rock-solid product and company to deal with. I've changed homes twice in the last few years, but I always find my way back to these filters. I even ordered a weird size online once and they called me to ask if I was sure. Amazing. Thank you.
