Using these in grooming salon and they are doing a great job.

Brian Sharlow 13 days ago

Quality filters at a reasonable price. Allergy and fine particulate seem to be kept at minimum. I've been using them for several years and haven't found a comparable filter for the same price.

Filter was easy to order and also got a discount. Delivery was fast. I have been ordering from Discount Filters for a few years now and am never disappointed.

Steven L Howard 24 days ago

Too early to effectively rate these filters. We should get 3 months of service. But in the desert environment, dust and allergies are factors. If we get two months of service, we are satisfied.

While I may love the product I love even more the best customer service I have experienced in a very long time. One of my items was stolen from my steps and this company replaced them no questions asked they are awesome!

Bob Houlihan 27 days ago

I have been using your company and this product for about 5 years. The company and the filters are top notch. When you price the individual filter the big box stores can’t compete price wise. Granted the element is not wrapped in a shiney wrapper but comes packaged in a brown box. The shiney wrapper or the brown box end up in the trash.

Peter Sadler 10 days ago

everything was easy the two boxes came through in good shape but I won't put one in till probably this September.it was a great deal especially with the percent off.thanks Pete

Charles Mallory 0 day ago

Filters fit perfectly. Changed monthly. Inspection of used filters and of the air handler,downstream of the filter, indicate the filter is doing a good job of keeping dust trapped.

matt jeziorski 4 days ago

i was quite skeptical about ordering air filters on line without first seeing the product. i was surprised to find a very well manufactured product better than what i was buying at the big box stores. my only complaint,which really was not a fault on the product, it was raining when my order was delivered. the outer filters where wet and now their warped. if they where wrapped in a plastic film i believe they would have survived. i would assume it would add to the cost.

I love buying my furnace and fridge filter from Discount Filters. The quality is great, the service is great, and the folks there are great. The prices are outstanding and the filters do exactly what the more costly name brand filters do. I have been buy the fridge filters for a couple of years and just got the furnace filters at a great price. I also just remodeled my kitchen and I can't believe how many filters all of the new appliances have. I'll be a lifetime customer! You can't go wrong here, folks.

These filters are about 1/3 the cost of comparable filters I can find in stores around here. I bought a box of 10 filters because I always want to have fresh ones on hand. They arrived a few days ahead of the listed schedule, and fit my furnace perfectly. It is holding up well after about 3 weeks of use - I have had some filters that buckled under the air flow, but these work fine. Very happy with this purchase, and will likely order again when I need more.

Susan Gaddy 18 days ago

I had read many reviews before trusting to purchase from a company I didn't know. Thankfully I did purchase from them and am very happy that I did. I purchased twelve filters and when the boxes arrived there were only eleven. I emailed them with the problem and IMMEDIATELY they responded with an apology and corrected the problem the next day by sending my missing filter with additional fillers for my trouble. Everyone can make a mistake. ........it is how that mistake is treated that impresses me and keeps my business. Will be ordering again. Highly recommend this American company.

AC Filter order was delivered when promised. As the DiscountFilters customer service rep said, their filters are spec'd to be about 0.5 inches smaller in length and width than the nominal dimension; however, that size difference didn't cause any problems in using the filters - they fit terrifically.

Gerald R Graczyk 13 days ago

I accidently double ordered my furnace filters, but when I looked them over, I decided to keep all of them. My service rep. who came to perform the early spring checkup said that they were very good. He also said they have a very good air flow.

Patricia Baker 29 days ago

I have not yet used these filters but they appear to be of the same design and equal or better quality compared to the filters I have purchased at retail. The cost saving over the retail price is significant and the ordering is easy and convenient. They arrived on time and in perfect condition.
