I like it.

It's difficult to tell when one filter is better than the other, but the air in my house seems to be clean. Plus, I think it helps in allergy seasons. Of course, one cannot avoid going outdoors in allergy season, but when indoors, I think your filters help to remove the allergens.

These cartridge filters fit the old electrostatic filter housing just right. The MERV 11 filtration system does a good job for our house. Lasting 4 to 6 months at a time. Thank you for easy ordering and prompt delivery!!
