I would highly recommend this company to anyone who needs quality A/C filters
We have been using your Biosponge Filters approximately 10 years. Due to my husband having asthma and other allergys and as well as pets in the house the Biosponge has really worked well for us. We always change the filter monthly and installation is quick and easy. We order online and ,we choose, to get a year's supply at one time. We receive discount coupons from the company which is a nice touch. Their Customer Service is excellent. I would highly recommend this company to anyone who needs quality A/C filters. Thank you for so many years of great service.

Biosponge AC Filter
Am very happy with this filter. It fits perfectly and will last 2 months before a replacement needed. Service is excellent and I highly recommend. Heard about them from my neighbor who got a new Trane and the tech told her about this company.

I have been using Biosponge Smart filters for almost 15 years. We recently moved to a new location and noticed the cheap filter had not been changed in many months. We measured the grill size and ordered our Smart filters and within three days our filters arrived and fit perfectly. I would never think of using another company.

"Wow, that was fast!"
Years ago our a/c technician recommended we use Biosponge a/c filters, and we have ever since. Ordering is very convenient, and we appreciate the coupons that are available each month. What's more, Filter Factory has always filled and sent our order so soon that I always seem to exclaim, "Wow, that was fast!"

Premium A/C Filters
I have been a customer of Air Sponge Filters for a number of years. They work exceptionally well in my Trane System. Filters normally last for two months before needing changed. Not only do they function as air purifiers, but also come highly recommended by many professional people. Ordering online with delivery to your door cannot be any more convenient.

I would recommend highly to everyone
I've been a long time customer over 10 plus years and will not use any other filter!! The custom fit frame seals the unit and the bio sponge filter has no equal all air must go Thur filter. Just replaced my old ac and the old coils were still clean. I would recommend highly to everyone interested in good quality clean air !!

You will never go back to others
We have been using these filters for "many" years and found they are the best anywhere. Several people in our family suffer from severe asthma and this is the only filter that has been excellent for us. So if your are looking for a filter replacement that takes care of it all try this company. You will never go back to others.

After having our new heat pump installed
After having our new heat pump installed in our attic, the filters we used to use no longer fit. They would get sucked into the furnace and were the devil to remove. (Plus I don't think we were getting the full benefit of using a filter!). One of our A/C technicians suggested we use the Biosponge system. He measured the frame size we needed. From their website it was easy to order the correct size by following the simple instructions. The first order costs more because you have to order the frame; future orders you only get the inserts, which come in a clear plastic bag. The website also gives you the option to send yourself a reminder as to when to replace the filter.

well constucted well fitting filter and housing
Nice to have something that didn't come from China. I just changed my first filter after 2 months and it didn't appear to be very dirty but I'm sure it was. My old washable one was pretty sad. 3M I think

fits just right
I have an odd sized a/c unit and have never found a filter, except the cut it yourself type, that will fit. This is a perfect fit. It is winter and I have not used the a/c since the arrival but am thrilled that it fits.

Biosponge A/C Filters
I have been using Biosponge A/C filters for more than 10 years. They are the best filters I have ever purchased. They keep the inside air in the home clean as well as the A/C coil, which keeps the A/C unit running smoothly. I highly recommend them and plan on using them another 10 years. Mike R.

I have been using these filters for many years now and wouldn't think of using anything else! I always believe you get what you pay for! The less expensive filters you can buy just don't work as well.

Cleaning my air
This is not my first time ordering from this company and won't be the last time. I did go back to the store bought to try to save money and boy was that a big mistake. So I am back and I will stay a customer till the end.

Superior over the "store bought" types
Easy to install & maintain. Filtering ability is superior over the "store bought" types. The support frame is very sturdy and the exact size for my AC system. The service of e-mail furnace filter change reminders is a welcomed plus.

"The Air Sponge is just what they advertise, it is the best filter around." It is so convenient to have them make a permanent very sturdy attractive filter frame and then provide you with a year supply of the highest quality filters."
