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

I’m very satisfied with the results. I see more on this filter than I did on my previous filter I was using. I’d definitely recommend them and purchase them again.

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 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!

Very easy to install. Remove the old filters, clean up, then turn the AC on and the air intake will pull up the filters into place.

These filters, proudly made in the USA, fit perfectly, perform admirably, and are competitively priced. The actual dimensions listed in the product description are accurate, a detail that is appreciated. I conducted a basic airflow test comparing these filters against a comparable MERV 11 Filtrete. Using a filter box and an inline fan, I measured the CFM for both. These filters showed no reduction in airflow compared to the Filtrete MERV 11s. It would be interesting to see the results when both filters are filled with dust, and I may test that if I can figure out how to get the same amount of dust into each filter. One minor drawback is the packaging. All six filters come in a single plastic bag, not individually wrapped. This could potentially expose them to dust during storage. As long as you keep them covered, they should be ok.

I have been using this brand for quite a while now and I have been completely satisfied with this brand. I change my filters every 3 months so it can get expensive buying filters. Since using these BNX 20x20x1 MERV 11 Air Filters the dust level inside the house has been a lot less and buying these in these bulk packs only makes sense at this great price. I have not had 1 single filter fail on me since using these and they fit my 20x20x1 filter housing perfect. I also love the fact that these are made from recycled cardboard, and they are made in the USA. The MERV 11 rating with these filters allow them to capture the smallest dust particles which I have noticed by having to dust less often inside. Overall these are my go-to filters now and I have been completely satisfied with them.

These are great filters. They are MERV 11, which means there are more items and particles that they filter out, 11 is on the higher end for home and office use, and cheaper filters can be as low as 2. These are low flow, meaning they collect many pollutants and particles, so you should change them regularly to prevent your system from working too hard. I change mine every 30 days. This is a high-quality filter, and I notice the quality during spring in the south with all the pollen. I saw much less dust and particles in the air over the MERV 8 that I replaced with these. They are excellent pleated air filters and great quality at a reasonably good price for the 6-pack. They are also made in the USA. 5 Stars all day and are great value for high quality.

Our old filter was in a really bad shape and we were is need of a new filter (quite badly) and were happy to try this Electrostatic 20x20x1 MERV 11 air filter replacement. It fits our unit perfectly snug, just as if it was made for it. The synthetic electrostatic filtration technology that should allow for industry-leading superior air flow and low air resistance while maintaining the highest grade level of filtration, is something that, honestly, we never heard before so we are true first time customers! 10 days after here is what we observed. Our unit started working much quieter than it always worked before with the traditional filters (we have a 3 year old hybrid system, heat pump with electric back up). I was actually surprised that the claimed superior low air flow resistance with the highest grade level of filtration turned out to be true, at least what you can tell by listening to your 3 year old unit work. It seems to work much less now and move air much easier! This is the first time we tried this type of synthetic electrostatically charged air filter and are quite impressed! For the price, it is really not that much more expensive than the traditional filters in this filtration rating (or even less if you compare the big name stores). But it makes your system breath so much better which, of course, will reflect on the heating/cooling bill and the life of your unit! This filter captures microscopic particles such as odors, pet dander, allergens, dust, lint, mold and dust mites making noticeably cleaner air in few days. I think we are converted!

Great quality filters unlike a lot of the flimsy ones you get locally. They have a great thick filter and seem like filter the air really well while still allowing a good air flow through them . I have inside pets so its a must that they do.

These are good midgrade quality filters. We typically buy the more expensive allergen ones. But these do the job!
