The quality of the filter is fine; however, cutting corners by making the size slightly smaller has resulted in making the filter too loose. I had to add a block to the edge so that the strong suction would not pull particles through the loose edge which would make the purpose of the filter useless. I shouldn't have to alter what I purchased to be the ideal fit. The cheap temporary filtrete filter I used fit like a glove. Can you correct this for me?
The filters came well-protected in the box. I now have a cat, so with this order I moved up the level of filters. I think my house is relatively clean, but when I switch out filters, they tell me otherwise.
