Merv 13
Sarasota—July 12, 2025✓ Verified purchase
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. Read more

Size is a bit short. Sloppy fit in furnace.
Mark D.—November 23, 2025✓ Verified purchase
Ordered 16x20x4. The actual size is a bit short. It’s really beneficial to have the filter true to the actual size namely, 16x20x4 . 15.5” is not 16” Read more

Incredible deal
S H Lam—February 27, 2026✓ Verified purchase
Pick this 4 pack for a great price, it's much better then going to the local store and getting a lower quality for more cost. We put one in the A/C unit and can tell the difference in quality of the air. The size is exactly the same as the one that we took out. Read more
