Review: American-made, high-quality filters at a fair price - I've been buying from Filterbuy for years now. If you want your indoor air to be as clean and healthy as outdoor air, you need to replace those HVAC filters every couple of months -- so you might as well get good ones. I have 3 pets, I live in a very urban area, and I cook at home a lot. These filters pick up everything. And I like that they're not stored in an desertcart warehouse -- they ship straight from the Filterbuy factory.
Review: Good Value - I think all disposable filters are very similar if you match the MERV rating. Therefore this filters are a good quality and excellent value.

### ⭐⭐⭐⭐⭐ Good Value

I think all disposable filters are very similar if you match the MERV rating. Therefore this filters are a good quality and excellent value.

### ⭐⭐⭐⭐⭐ Merv 13
*by S***A on July 12, 2025*

These filters are the best made filters I have found to date. Sharp folds, tight construction. They filter so well that I had to tape them, otherwise they are vacuumed by my Carrier system. Unfortunately, filter housings are very poorly designed in most AC systems. By blue taping the filters you prevent any filtering loss that will happen with most systems. Air quality has improved by a huge massive lot vs Merv 8 that I was using. These Merv 13 even help with fumes and cooking smells. I have some serious allergies and these filters are definitely a game changer for those who spend more time at home. I feel soo much better. Extremely happy with the change and the filtration capabilities. I have noticed no change in my carrier system performance whatsoever. I'm sure it is harder for the blower motor to use merv 13 filters, but my AC handles it perfectly. Merv 13 could be too much for some older AC systems, so always consider check your model and capabilities of it. My AC is purposely undersized. I run my AC for about 10 to 15 hours a day during the long Central FL summers. You can see how the new vs old looks in the picture after a hard month of use. If you can, get these, you will love them.
