Bought this in addition to the regular filter. First time ordering this particular filter and it seems to be working well. Wanted a washable filter to assist the regular disposable filter. So far, so good.

I love the idea of these filters and also love the quality of them ! Unfortunately I wasn't able to use them they were the right size for my furnace but which was 16x25x1 but the 1inch part slides down in and it's just a hair too wide to fit i was devastated ? because I wanted these to work so bad they are fantastic quality ,I talked to Ryan and he was so nice and tried to get another alternative but they didn't have one that was washable .but he kindly refunded my money .so I'm just going with regular ones

These are phenomenal, and so much better and more effective than the flimsy filters I had inserted before. Love them !

I really like these filters because you can wash them and reuse them. As a landlord, I changed my filters every three months and I bought two sets so that I can wash them and have a dry set to take to the house. It saves a lot of room and will eventually save money.

This permanent washable filter saves me time and money. I no longer have to run out to the store to buy a replacement filter. I just cleaned this one and it’s good to go.

Quality was great. No fault to Discount Filter, but it didn't fit. It was too big & Discount Filter immediately refunded my purchase price & DID NOT want the filter returned. I still would like to find a lifetime filter of the correct size to fit my furnace. I definitely recommend this company.

Can’t really rate at this time. The permanent filter for the heating unit makes sense for the price.

I’m very happy with my purchase. Ordered 2 so while one is being cleaned I’ll have another to put in furnace while it’s drying. I bought 2 for less then 1 at another store
