I have been buying all my filters (air, water, fridge) from Discount Filters for many years are they are quality filters at a reasonable price.

Paul G Simons 30 days ago

Better made than the HW store alternatives. The cardboard edge is stiff and more precisely measured. Fits opening well. Other filters were frequently a force fit.

I buy this 20x20 A/C filter, as well as two other sizes, from DiscountFilters.com. I'm well satisfied with the quality, price, and delivery. I'd recommend this company. I've also used their refrigerator filter for my Samsung refrigerator for several years. They work great and cost a lot less than what I can get at Lowes or anywhere else locally.

What is not to like? Ordered product. It was shipped next day. I received a few days later. Everything seamless for less cost and better quality than if I traveled to big box store and purchased. I am a 5-year customer of Discount Filter. Plan to stay.

Thomas McCormick 24 days ago

This filter was recommended by the DiscountFilters Chat representative which was so helpful! There are so many filter options that I wasn’t sure which to choose given my household pet and local environmental allergens. With the help of DiscountFilters Chat, I’m confident in the filter quality and ordered a year supply so I can diligently replace the filter in my HVAC system to keep it running smoothly and keep the air in my home clean and safe. Def appreciate the outstanding service DiscountFilters provides from ordering to delivery! My experience has been great!

Thomas Conant 3 days ago

The only problem I have with your product is that is 19.5 by 19.5 and not 20 x 20 as listed, resulting in me having to tape the filter in place so that it doesn’t fall out of place when the air is off. My filter mounts horizontal in the ceiling and after a few cycles it moves enough to fall from the mounting clips unless I tape it in place when I install it. Not a problem when I was younger but gets harder with each birthday.

They do a good job. If my wife’s allergies kick up all I have to do is turn the central air fan on to give almost immediate relief. I replace our filters every two months due to allergy concerns and have found these to be of good quality and affordable.
