Very good. Works great

The allergy filters are good quality. I notice a big difference in a lot less dust collection on furniture with these filters. And Discount filters have hard to find sizes. I recommend them to anyone that wants a good quality filter.

These work great with our system and the filters are hard to find locally at time.

Product is excellent - well made, shipped promptly and does what it’s supposed to. The one issue I have is that figuring out discount codes is a pain because I might get one code from discount filter directly but then I find another better one on my own. Hard to tell if I’m getting the best price available.

Filters that were not available at either of the major building supply stores or at a couple of specialty stores were easily found, ordered and delivered here. The product is perfect, the shipping free and the process seamless. My “go to” for all my filter needs in the future.

The dust sticks to the filter like glue. These are the best filters for the money, good prices and fast shipping. Discount Filters is the best!

The AIRx Allergy Filter Merv-11 works and lasts as long as the much more expensive name brands. Mine is an odd size not even carried in the big box stores. Discount Filters always has them in stock. Great service as well.

I've been pleased with it for the past several years. Easy to purchase, convenient to get.

Filters were delivered in two days and work as well as the big brand versions.

Cameron 0 day ago

Works as advertised. Value for money 3 stars because it is paper and fibers. So, monetary value is what is expected.

Richard Stricklin 0 day ago

Product appears to be an excellent value. Problem is with delivery. Was delivered by USPS (Post Office). Was delivered in the rain without any protective covering over the cardboard box. Needless to say, the product was wet on the outside filters, but are usable after drying. If I had returned at a later time, this may not have been true.

Colette Profitt 21 days ago

Great quality and good price. Same size printed on filter as my previous filter from a different vendor, did not fit as tight which is good because the other was too tight. Shipping was really fast. I will purchase from them again next time I need filters.

Michael Farris 26 days ago

Product arrived in a few days with normal shipping, undamaged and exactly as described on the site. I will definitely reorder when the time comes!
