Love this product. Bern using it for years. It does what it’s supposed to do. Easy to install. Great value.

Happy to find a filter supplier for such an odd shaped one. Home Depot and Costco didn't have it. Great value and timely shipment!

My filters are an unusual size, hard to find in retail stores but thanks to discount filters I always have a supply on hand they’re of excellent quality and great price.

So far, the only thing we can say, : shipping was accurate and fast, staff very friendly. Experience of material will come with time :-)

This filter size Lowe’s or Home Depot do not carry. Found it here and the prices were better than similar size filters at HD and Lowe’s, but not the right size. They were delivered quickly with no hassle. Very Good!

Does a great job pulling dirt, dust and debris from the air.

What I expect for a A/C filter, however I feel it's a bit expensive.

Paul Reeves II 26 days ago

The product is adequate, I have yet to receive a delivery of filters without damage to the shipping box and filters. The filters have to be bent and formed back into shape to fit.

If it wasn't for the discount from discount filters, I wouldn't have bought them.they are too expensive.

I have ordered this product before and it "gets the job done". However, I will NOT be ordering thru this company again. I can get the same filters at the same price on Amazon (without delivery and tax). They are supposed to be a "Discount ..." filter co. and I don't feel that they are.

It is very easy to order and have delivered. These filters are perfect for my use with the A/C. Much more convenient yhan running to the Lowes or Home Depot .

Superior product, right size for our system, priced better than local suppliers and great Service from Discount Filters. I've recommended to others and will continue to do so.

Thus far, no negative issues. Very pleased with our purchase. Will use again.

Found the service to be fantastic, and the filters work great. Dust is noticeably reduced and the air seems healthier. Great price as well.

I have used the product for many years and found it to be an effective filter medium

Rachel Murphy 27 days ago

This was my first time ordering with Discount Filters. My filters came quickly and they fit perfectly. My filter size is not found at my local hardware stores, so this works great! Will definitely be ordering again.

Great deal, last time I went to large box store and had to special order and pay a premium plus freight for the filter. I ordered from discount filters, no premium price, no freight and delivered in one week. Too bad I ordered a years supply. I wish I could use them more
