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 that any other. I've got a new AC & I will be using these. Have recommended them to others and they're pleased. Love company's email reminders & discounts!! PLEASE keep making them!!

Great Furnace Filters

I like the quick turn around service when I order from the Filter Factory. The Biosponge Plus furnace AC filter refill fits exactly so I do not have to cut it.

Great filters

These filter pads are custom made to the exact dimensions you need, so easy to replace. And they only have to be changed every two months. I order 6 at a time and they are delivered in only a few days.

Best Ever

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

Fantastic

This is the best air filter ever. Because the frame and filter is custom made, it essentially fits perfect preventing gaps that allow unfiltered air through the A/C handler. "Dirty" air going up thru the handler reduces efficiency and allows dirty air up through which eventually clogs the duct work. The filtered pollutants don't go all over the place when filter is changed like regular pleated ones do. I have used these now in 3 different homes in the last 19 years. Service is fantastic and I appreciate the convenience of quick turnarounds, reminders, discounts, and the reward system. Thank you so very much for a quality product.

Biosponge Plus Review

I received my first Biosponge Plus filter when I replaced my old central air conditioning system in South Florida in early 1990's. We immediately noticed a big reduction in dust throughout the house. We've used them from that time on. When I purchased a new home in Central Florida, I immediately ordered a new frame and a packet of Biosponge Plus filters on line to fit that system. I do not see us ever using anything else.

biosponge filters

We've been using these filters for 10 years, 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!

Biosponge refills

I have been using the Biosponge Plus refills for well over a year now. I find the filters do an excellent job doing what they are supposed to filtering the air moving through my air handler. They are easy to replace and are extremely cost effective. I would highly recommend these as I will continue to use them into the future.

Filters

We have used these filters for several years and are very happy with this product. However, any time a delivery is being made at a home with a covered porch I feel the delivery company should take a few extra steps to place the package in a sheltered area. I recently ordered filters at a fairly significant cost that were left outside the garage in the pouring rain. The filters are great but not happy with the delivery service.

We have used the great biosponge filters for 6 years with GREAT SATISFACTION but were not happy with your new shipping method of only the plastic wrap. The cardboard shipping box previously used was much superior and the filters arrive in FAR BETTER CONDITION. PLEASE CONSIDER!!!!!

Review

Arrived on time and in good condition. Instructions very clear. Easy to install (with or without the frame). Certainly does trap allergens (I have a dog who is shedding now and a cockatiel molting now) but air inside is fresh and clear. Have used these filters before and are the best for the money. Being able to state specific size of opening is a definite plus. Never have had a problem with these filters and would highly recommend them to any one looking for an easy to install and quality filter.
