Filtrete 20x20x1, AC Furnace Air Filter, MPR 1200, Allergen Defense Odor Reduction, 2-Pack (exact dimensions 19.69 x 19.69 x 0.81)

Great filter for animal owners

Easy to install feel high quality just a little pricey

Works.

Hasnt done much for my allergies compared to a standard filter. Still seems solid overall.

Taped it to the back of a $25 fan and now I have a HEPA filter for super cheap. The first time I spray painted near it it loaded up quick so worked great.

This filter helped reduce the puppy odor I had in my house!! Now its bearable!!

I have nothing good to say about these filters. I very rarely write reviews but these were so bad I feel it necessary to warn the public. DO NOT BUY THESE. Mine came bent on almost every side, they were also too big to fit neatly in to my air conditioner. I got a 2 pack, after the first one was installed I kept thinking my air conditioner, which is only 1 year old, was either broken or dirty, I kept coughing up dust and kept telling my landlord that I had just changed the filter to an expensive one. I replaced it after 21 days because of the dust, I kept finding black dust all over the apartment. When I installed the 2nd one, I saw the same black dust on both sides of the filter, the carbon is supposed to only be on one side, but it was on both and there were cotton (or whatever the material is) hairs coming out of both sides, looked like it had already been used for a year, totally dirty. I kept it wrapped before using it so it was definitely how the filters came. Too late to return them now but Im going to complain to amazon and the seller, what a rip off. Air conditioner repairman came to look in to my dust problem, it took him exactly 1 minute to figure out what it was, and it was these air filters, he told me never to buy them again. So 32 dollars wasted on the filters and 200 dollars for my landlord to pay the repairman, simply because I bought these. DO NOT BUY THEM.

How stupid do you have to be to look at a box containing 2 filters that are 14x24 and send it out as 2 20x20 Filters. 1. Learn to READ! 2. Take an elementary grade geometry class!

The charcoal really works to remove odors from cooking, pets, and that peculiar smell old houses sometimes have.

Bought a turn of the century home that had been shut up for years. Took the old musty smell out in a couple days.
