This product was recommended by

This product was recommended by our AC maintenance company. Not only is it a great product that works better than the filtretes we were using but the cost is good as well.

First time buyer.

These filters are a perfect fit. In the past , due to not knowing my exact size, I've bought some filter that you cut to fit. Although it did collect dust and dirt, it didnt give you needed protection that this filter does. I bought a 3 pack so I can change them as recommended.

Great filters. Better than what we've purchased previously at the supermarket.

Filters arrived on time, and in perfect condition. Interestingly, they actually fit the ceiling openings better than my previous filters from Filtrete. They've been in place for a week, and the air seems clean. So far, we're very pleased. We plan to continue using these in the future.
