These filters are great and pick up quite a bit of dust, dander from my parrots and the air smells fresher when I put the new filters in. I use Merv 13 filters because they are the best filters for my home. I use the 20x20x1 size filter. These filters are a little more expensive, but it's worth it.

I was hesitant to switch to a different brand than what I usually buy from the big box store. But once I tried your filters, I quickly saw that there's no lack of quality. Plus, I saved a ton of money with your filters. I've been spreading the word about your site. You've got a loyal customer for life with me!
