Affordable and effective

I love these filters. Affordable and effective. It's amazing to see how much they have collected when it's time to change them. The subscription service is great. A little extra savings and a subtle reminder that you forgot to change them. LOL. But I usually notice when it's time if I forget, I find myself sneezing and having itchy eyes in the house. Which always improves once I change them Highly recommend these and Filterbuy

My filters came nicely boxed

My filters came nicely boxed and they were in perfect condition. I replaced the same size that was in my air-conditioning vent area and I had a gentleman out to clean my vents and he told me my size is actually probably a 16. 5 so it would be a 16. 5 x 25 by one. Kind of crazy, but the product was perfect.

The quality of the cardboard

The quality of the cardboard used to stabilize the filter is far above anything I have bought at the big box stores. . I used to be in the HVAC industry so believe me when I say the cost is very reasonable. I will definitely be a customer for life. Thanks for making such a quality product. .
