BNX TruFilter 20x20x1 MERV 13 (4-Pack) AC Furnace Air Filter - MADE IN USA - Electrostatic Pleated Air Conditioner HVAC AC Furnace Filters - Removes Pollen, Mold, Bacteria, Smoke (Actual Size: 19 11/16’’ x 19 11/16’’ x 3/4‘’)

Shipped fast, pretty good price and true to size on the 20x20x1. No inner protection packaging so there is a chance for damage during shipment. Mine was in almost perfect condition though. Havent used them yet so, will come back in a month to give honest review of performance.

I use these filters in my HVAC unit and find them easy to install and remove. They do the job of keeping my unit clean, free from dust and operating smoothly.

These filters are amazing and made in the USA!! We suffer from what seem like year round allergies here in Florida and it’s starting to get worse. We picked up these filters to make a CR box to give it a go. These filters have worked wonders and I’d use them for any thing that requires a filter. I plan to switch all my filters the this brand from now on!

1. Highly comparable to more well known brands for air filters at a very competitive price 2. A visible and prominent arrow indicating the direction of airflow is very helpful. It is very noticeable and it helped make sure that I was able to put it the right way 3. The filter is looks sturdy 4. I also liked that it had a box for me to write down the date when the filter was installed- it is something that is so easy to forget otherwise 5. I liked the packaging, the pack of filters came in a transparent plastic wrapping which helps preserve the unused filters. The other brands I have purchased previously didnt provide the additional protective layer

I just installed this filter, so hoping it works, but... It advertises as 20x25x4. It isnt. It is actually 19.5 x 24.5 x 3 5/8. It does not fit tight in my system. Im hoping it seals well enough, and doesnt let the air flow around it. The photos are this filter next to the Honeywell original filter, which fits snugly and worked well.

Arrived as promised. Four pack is convenient and cost worthy.

This filter is the best I have found. Our home had no carpet so the air filter catches a lot more dust. These catch an incredible amount. I change them out about every two weeks or when they turn dark gray in color. Other brands take longer to turn dark but I think thats because they arent catching all the dust and pollutants.

High filtration at a good price

I have been buying this brand for a few years already and for the money they are solid and work well with my 3 ton centralized a/c unit. I have a cat and a dog that shed so much I wonder if they would go bald one day. I change them every month and no a/c coil issues so far.

be able to see how well they are working. I decided to use my filters to construct a corsi Rosenthal box to help clean the air in my home. I am immunocompromised and wanted to take steps to make it safer for me and my loved ones to gather. Its pretty incredible how noticeably cleaner the air felt after turning on the fan and letting the filters go for a few hours. I have awful seasonal allergies that have basically dissappeared this year because of these filters. So even if youre not using them to prevent illness, I still highly recommend them for any type of environmental allergies. After a month of using these filters, they have visibly started looking a bit dirty and have picked up so much dust and cat hair. They are really doing a great job in cleaning the air in such a short amount of time. I have been recommending these to my friends and family. After these filters become too dirty, I am absolutely getting more. I cant believe Ive lived so long breathing in dirty air. Never again
