I have used these filters for more than a year now and have been very happy with their performance. The cost is great when purchasing in quantities. With the Canadian smoke I feel my indoor air is cleaner.

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.
