Great filters. I use them
on September 23, 2023

Great filters. I use them for my furnace and my overhead air cleaner in my shop. They work great. I also really like that I can schedule the delivery of one filter every quarter, and I don't have to think about swapping out the furnace filter. And the 1" pre-filters I buy for the air cleaner really save the very expensive 2nd stage filter. I have been through about 12 pre-filters and the 2nd stage shows very little buildup. Amazing! (I just wish the sold the 2nd stage filter.)

This is described at fitting the same the Honeywell Home filters. They do not. I bought filters that are 20x20x4, expecting them to be the same dimensions as the Honeywell Home filters of the same size, but they are not the same size. They do not fit and this company has not responded to my request for a return. Completely unacceptable and I will never purchase from this company again. I do not recommend any of their products. Do not purchase from this company!

DO NOT PURCHASE FROM THEM!
on September 3, 2023
Posted by: Vanessa F.
Do not purchase from this independent filter company just because youre trying to save a buck. We thought we were being smart when purchasing a years worth of filters from them given how much money we were saving. Turns out their same version of the Honeywell 20x25x4 Merv 13 isnt the actual size we needed. When trying to exchange the filters, turns out they dont actually make the air filter we needed and when we tried to return the filters, we found out we were responsible for shipping costs which ended up being twice as much as the filters themselves. So now Ive got 6 filters that we can not use and nothing that we can do about it.
