Just started using this product. Too early to tell how it’s working. Not sure I will be able to tell if it works any better or worse than the last filters I used

These filters made my furnace not be able to breathe. I had to call a technician to come to my home and it cost me $254 for him to tell me that I needed different filters.

I've purchased this item several times. Overall I. Stified with its performance The only negative is, the filter turns black (some of them, not all) after about 3 weeks. No smokers in the house. Minimal fried foods, we seldom use candles. My Ac guy said it could be activated charcoal but the package didn't say that. What causes this?

Very substantial filter for allergens and pollen.

Best filter on the market!! Cheapest place!

They work as they are supposed to!

To big, sizes are all different

Works great and fast shipping. Thanks

great value on great filters
