Antimicrobial treated; dry tackified polyester air filter media. It’s Aegis microbe shield not only eliminates the filter as a potential breeding ground for micro-organisms, when tested, they reduced airborne micro-organisms by up to 86.5% in a single pass through the ac filter!

BioSponge plus features a special dual density design to allow for a extended 60 day filter life and a 60% increase In efficiency over regular BioSponge media.

About AEGIS Microbe Shield

Aegis technology stops the filter from becoming a place where mold, fungi, bacteria, and other airborne germs can grow. Imagine the surface of the air filter like it's covered in tiny, electrically charged swords. When germs touch this surface, the 'sword' breaks through their outer layer and the electrical charge zaps them. Because this process doesn't give anything away to the now-dead germs, the antimicrobial power stays strong. This means the 'sword' is always ready to take on the next germs that come along.

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.

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.

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 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.

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.

These filters work for me. We've been using them over 5 years and they're the best. Filter Factory does a good job of nagging me to buy them so I don't forget. Shipping is fast and free, so what's not to like.

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.

The Filter Factory is easy to deal with and has excellent customer service skills. The website is a breeze to use and the filter quality is above all others I have tries. There is no reason to look any further for a filter replacement source.

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.

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.

Suggestion For Filter Factory

We have been using these filters for many years & they hold up well. It's a nice convenience receiving them delivered. I do wish the frame had a hinge on each side to open when taking the old filter out & replacing it with a new one. We would sure buy that Filter Factory.
