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‘’)

This 4 pack was an excellent value. It is cheaper than buying a single higher quality filter from the grocery store for $14, especially after inflation. I wish I would have found out about these years ago, because it would have saved me so much money. Plus, these are super nice quality and super sturdy. I have pets, so I am super picky about my air filters and need more than the flimsy ones, and I also change mine out monthly due to the pets.

These MERV 13 AC Furnace Air Filters appear and feel like premium filters. Its hardly scientific, but Ive only sneezed a couple of times since installing this filter, and I havent woken in the middle of the night from breathing problems. Seems to be working great.

Good price and good quality fast delivery

Came as promised. It was what we expected. Everything is expensive anymore, but price seems a bit high for what it is, but I think no more than other brands. So, overall, good.

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.

The first filter I put in...buckled in the middle. I didnt notice how bad it was until I went to replace it. I put another one in,..turned on the fan this time so I could observe it. It buckled in the middle almost immediately. Not going to buy these again....just way too flimsy

Slightly higher filtration levels with these as well as a lower price. Won’t be using one for a month or so, but visual inspection shows good quality construction

Merv 13 filters. Very good, fast shipping.

I really like these filters. They seem to not be too thick. Im expecting them to work well. Looking forward to making this my choice filter.

I tape the 20 x 20 filter to a 20 box fan, to clean the air in my home. Really helps keep dust down. I dont have a forced air furnace.
