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!

Excellent buy

The shipping was quick. The filter seems to be working well. With two old shedding pugs, the air in my house needs all the help it can get. My allergies seem to be better. If they really do last 3 months, then this was a fantastic buy. Only time will tell.
