BNX 20x20x1 MERV 11 Air Filter 6 Pack - MADE IN USA - Electrostatic Pleated Air Conditioner HVAC AC Furnace Filters - Removes Dust, Mold, Pollen, Lint, Pet Dander, Smoke, Smog

In size and appearance they matched my existing filters, so thats good. I dont have any way to verify their filtration claims, but they seem correct. The company is pretty young, formed early in the Covid epidemic, and built a good reputation selling Made in USA masks and filters, so Im pretty comfortable using their filters. A word of caution - if you are switching from low MERV filters in an old HVAC system to high MERV filters for the first time, check with your HVAC tech to ensure the blower can handle the flow restriction. The basic MERV 2 fiberglass filters were designed to just protect the blower, not your lungs, and the system was designed expecting that (minimal) level of flow restriction. The added restriction of a MERV11 or MERV13 filter can cause excessive blower wear and premature failure. Which might be a good excuse to upgrade the old system anyway :-)

I replace the filter religiously every three months as recommended, and I have used many different brands with varying results. I am familiar with the Merv brand, but really haven’t used them before. The price for the 6 pack was good, and I am happy with the quality of these. They seem to be better constructed than some, and are a snap to install. Good, quality filters and I will be a repeat customer. Recommended.

I couldn’t be happier with these! They work great! They are all so easy to remove and reinstall, clean ones! Plus the quality is amazing! And the price is even better! We had a hard time finding these for the past year around where I live so when I saw these, I had to immediately order them so we could switch out our old ones and have extra on hand! They’re of nice quality, and even though they came in a cardboard box, they did not bend or break! High recommendation from me!
