Product was identified on box but not on individual filters. Had to call to see if the wrong filters were in the box, should mark individual filters, like "merv11".

I am certainly no expert on rating furnace filters but I do know in June when the smoke from the Canadian wildfires was blanketing this area, the filter nearly turned BLACK within two days, so it was definitely working.

Kathleen M Gould 9 days ago

Been ordering these filters for a few years and the cardboard framing was not same quality as in the past and certainly not as shown in the picture. Kind of disappointed.

WILLIAM T. CRAWFORD 28 days ago

Our HVAC Co.,after viewing and installing the new air filter in our furnace, he advised this was the most generic, non marked filter he had ever seen. The filters shipped to me recently had " Allergy" or other markings on it. He also advised they didn't "appear" to be Merv 11. All these filters had was a check mark on Merv 11.

Barbara G. 18 days ago

The product is usually received in good shape! The box the product was in had big gouge and crushed. The product itself had torn cardboard and smashed filler near bottom half....on one of the filters. Other one wasn't too bad. I fluffed the damaged one up as much as i could and am using it in the furnace first....I'll see how it works. Thanks.

Tom E. 6 days ago

Filters arrived and are as represented. I have used two of the same filters filters before this order and they worked fine. Seem to last about 9 months before a change is required. There are so many filter sizes available that it is confusing to know what to order. Often the sizes given are nominal, for example my filter is called out as 5-inches thick but it is actually 4-3/8-inch thick. So order by using information from the last filter used. Read up on the MERV rating and use the rating called out for your heating or AC unit.

Customer 29 days ago

The filters came damaged. I Emailed this seller regarding the state of the filters along with a photo of the damage and the order number, and they did not reply. Update: The seller is sending replacements. Therefor I changed my review to three stars. There is clearly an issue with their Email system because I definitely sent the information from my hotmail account and the seller claims they didn't receive anything.

The filter does what it's supposed to do. Even when it's ready for a change, it doesn't seem to inhibit airflow very much. It also happens to fit very snugly into my furnace, and I think that's important to trap particles as it's supposed to.
