I receive them timely and undamaged. I can't tell how well they work but I can tell they are substantially better quality in design and execution than those grocery store brands. It really IS going to filter versus just fill that space. I have happy and feel I have made a good decision for my air quality!
I have not installed my filters yet. Ijust had a brand new A/C installed. Best Home Services put in there own filter which is good for 30, 60 days. So until then I cannot give a review. E mail me in two months and I will have more info.
