Great home filters at a great price. . .

Great deal on these filters. We have three rescue cats, one of which I am allergic to. I've noticed less issues since switching to this brand. I change my filters every 45-60 days and noticed the filter went in bright blue and came out a medium gray color.

I am very happy with

I am very happy with my filters. I needed an unusual size. I previously had to buy 3 smaller ones and duct tape them together every 3 months. Your filters came quickly, damage free, and is a much better quality. It took less than 30 seconds to change out and I noticed a difference in my air quality that same day. I bought a year's supply, so I will definitely be buying again next year!

I purchased 4 of these

I purchased 4 of these last year but didn't create an acct. I didn't pay close attention but I thought the pleats were evenly spaced. These, that I purchased this year are not. The one that measured range from a1/2" to 1-1/2'. and they are placed in the frame crooked. I have an old flip phone and cannot provide you with pictures nor video. otherwise, a GREAT filter!!
