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

Just the right size furnace filters they fit as should and are very durable and not flimsy like others, they are comparable to the 3m but at a fraction of the cost.

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!

These work just as good as the name brand and I was able to get a 3 year supply for the price of 3 of the big name brands. They work just as well.

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 :-)

These filters are sturdy and look to be every bit as good as other filters Ive used. Ive used different sized filters from BNX before and they performed as expected. I have no way of testing whether the merv rating is accurate but nonetheless feel good about using these filters in my home.

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.

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!

MERV 11 is a good balance between air flow and filtration capability. I tend to use better air flow rather than filtration, but this surely needs to be considered case by case per family respiratory sensitivity. Better air flow is also easier for AC unit to function, make sure to Google the MERV standard if any question.

Great for the price and lightweight yet durable. Also filters a lot more than your typical filters. 6 for the price of 2
