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

The filters I received don’t have any carbon on them. Sad!!!

I honestly do not smell a difference.

These are great and worth the little extra that they cost! I live in a 40 year old home with 3 big dogs so filtration is important! Ive tried a lot of others but I will stick with these.

I order filters way in advance. I have not used these as of yet, and probably wont for about six more months. They seem to be fine. I always use Filtrete Filters to save my air system. They re Top Notch!

Like these filters and they work as advertised. I will continue to use these on an ongoing basis.

The 20x20 in front of box fan are odor and dust eaters to the max. Crushed a combination of desert dust+pet+smoke etc. to clear air and soil filters w/in a month. Was impressed enough to write this very positive review. Making repeat of this purchase.

Works.

I have severe allergies & asthma. I can tell a huge difference when I use these compared to the lower MPR ones. I never in my life imagined not buying the cheapest sir filters but here I am... I cant recommend these enough! If you have any breathing problems, trust me, you need these things!

Thats a big 10-4 on the odor reduction, thats for sure. I use one in my furnace, of course, but I also use one in the room where I keep my cat box (I have it hooked to the back of a box fan) to reduce dust and odors, and it definitely works well for that, too.

These filters have made a huge difference in our home. We have multiple animals, and keeping the house smelling fresh, is sometimes a hard task. These filters helped get rid of the animal smell in our home, and has reduced the amount of dust and allergens in our home. I have to dust less than before! We loved that we didnt have to go and find the right size at a home improvement store. Very easy to select the right size for our AC.
