Filtrete 12x12x1 Air Filter, MPR 1500, MERV 12, Healthy Living Ultra-Allergen 3-Month Pleated 1-Inch Air Filters, 4 Filters

Fit perfectly and Im not sneezing my head off every morning

Im glad I did order replace air filter for my furnace to keep clean & thank you very much!

I have four animals in my house and these made a HUGE difference in my allergies. Two cats and two dogs (if I dont sweep twice a week it looks like a furry animal was mauled across my house, thats how much hair sheds off my animals). I often have to vacuum the pet hair off the intake and sometimes off the filter because it gets covered so quickly, but it works very well and again, is a huge help with allergies.

I know their actual dimensions are close to their nominal, but these Filtrete filters are bigger than anybody elses. I had to crush two corners to get them to go into my furnace filter intake.

Better than the cheap stuff. Hopefully they last longer than the other ones.

These did an excellent job, but they will put a strain on your furnace if its not properly sized. So if your furnace takes a much lower rated filter that has better air flow, and you want to switch to nicer filters, then you might need to think about having a professional come out and putting in a bigger filter box.

my go-to AC filter for best performance. Just remember to check and change ultra-filtration filters frequently, as they trap so much dust and ultra-fine particulate matter that air flow can be seriously limited by a too-dirty filter. You may be surprised at how much dust is on your filter the first few times you begin using this. I am very happy with the performance.

Easy to install.

The air filter worked well for my house

The 12x 20s are getting harder to find. This is a great brand and easy to swap
