Filters Fast 18x30x1 Air Filter Merv 13, 1" AC Furnace Air Filters, Made in the USA, Actual Size: 17.75" x 29.75" x 0.75, 6 Pack

These filters work well. I change my filters about every 6 weeks and they have always caught a lot of dirt. The air seems fresh in the house. I buy merv 13 as it supposedly catches some small particles. Obviously I have no way to test this. However, my wife had covid and we live in a small townhouse. I ran the A/C all the time and I didn't catch it even though I was in the same room. The filters are well made.

These filters are just what we've been looking for with our oversized cold air return half the cost of other suppliers and I think it's a good value for your money

Filters are expensive but difficult to find a 30x30 size.

The replacement Hepa seems to fit and work fine . My contact dermatitis to dimethyl fumarate cleared up a great deal after first night's sleep . Slept like a baby . . . for a change . The new Honeywell purifier also working fine . I had them both going full throttle . I looked at the old complaints , and did not notice any problem . And I don't want to go looking for problem . It is a lot of trouble to take things back and then wait again for a replacement . Also put a MERV-13 Filtersfast in my apartment intake . Been fighting this allergy for over a year off and on , mainly on for the first year . Destroyed those 2 leather-recovered-with-fabric La-Z-Boy recliners from China , but the dimethyl fumarate got into the carpet and the air . Fingers crossed !

Filter was of good quality but was a different size than advertised. It fit but was loose Will buy my filters at a hardware store from now on so I will know what I am getting will not go by advertisement for fit size

These filters are the only ones I have found that do not get sucked into the filter opening. They are wider than most filters I have tried.

I been ordering this filter for awhile for the residential building I manage and They will last for 3 months , and up to 5 months in cleaner apartments.

I like these filters because they are good and cost effective. I like the minimal packaging - with no plastic wrap - because it minimizes non-biodegradable waste. I buy them because I have severe allergies and standard furnace filters don't help any at all. As you can see from the photo on the right, they are effective. The installed filter has only been in use for a couple of weeks and you can see how much dust it has captured. These are a good compromise between the pocket book and actual HEPA filters.
