I like that these furnace filters are made well. I purchased this brand a couple years ago. Decided to try a few other brands, one online company and two from local hardware stores. I eventually realized that although we don’t necessarily see the difference or realize if they are doing a good job since they are out of site doing their jib. The filters by DiscountFilter were made better, more support-both sides, and more fan folds doing the job. I have gone back to buying from Discount Filter. I would recommend this brand. They arrived quickly, were packaged well, and the price was comparable to other brands.

I use these filters for my downstairs and upstairs air conditioning units. The best for my home use.
