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‘’)

They exceed the specs of the heater / ac manufacturer and the price is right.

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

Works fine

I have used 3M filters in the past and been pleased, but these new filters work well and seem to be of a similar quality, but less expensive. I am also pleased that they are made locally.

We have a lot of dust where we live and this has made a noticeable difference in the amount of dust coming through the vents

On time great quality and perfect fit

Extremely well designed filter

heater and air conditioning, duct filter, to keep dust out of home.

Good price for the Merv rating

These filters work great in my two story home. They collect everything including dog hair from my three dogs who shed yearly.
