These filters--along with the air filtration system I had installed--are a God-send to me. The air in my house is now nearly hospital-clean. Through no fault of my own, my lungs are badly damaged and my breathing is so much better. I don't even mind the high price of these filters and I have to replave them more often than typical because I have four huge long-coated dogs and ten parrots. We are ALL breathing so much better!
