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.

Only wish filters were white

Only wish filters were white so they would hide in the vents better. Other than that small wish - these are great and easy to use and dependable shipping.
