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

I can definitely tell how crisp the air has become since replacing these flimsy strings the landlord gives us to this filter. We have pets, which was my main complaint. Doggy odor is gross and need to rid of it. The house has already improved in the few short days of using this product. I will continue to use these to see if our allergies alleviate.

Ok I am willing to say it might help with the stink. I am using upo what I have but seriously they are so flimsy. I had to tare it to get the used one out and I almost crushed tor and finangled the new one into place and I am praying it is in there right. I am going back to my old metal framed reusable one. these are way to hard to get in and out of my heater

I have not noticed any difference odor-wise between these and be standard allergy filters. So not worth the extra money (it does a good job as a filter though!)

These work well in our HVAC system, allowing a decent flow to filter ratio. Very pleased.

Works great, help keep the house smelling clean. Would set me back $15 a piece at my local Lowe’s or Walmart.

These are amazing. In my apartment, the air intake is right by the guest restroom, so the smell of poop spreads throughout the place. Since installing this filter, I havent smelled a thing.

Good package. Easy to unpack and install.

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.

Not having to go to the store to pick up a filter*priceless*

Gets rid of cooking odors, pet odors, I love these.
