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

Filtrete Allergen Defense Odor Reduction Filters are the absolute best. I bought them on the recommendation from our doctor and the day I installed them I noticed an increase in the air quality in our condo. We have a 1500 sq ft loft and a dog so a quality air filter is important for us. Im putting these on auto order so we have a new one coming in every month. They are the absolute best and we will continue using them and highly recommend them to anyone who considers the air quality of their home to be important for their family.

Needed a good heavy duty filter with a higher rating and odor control for the house. Filtrete cost a bit more but they are always worth it. These are pulling the pollen out of the air, cat hair, dust, and everything else thats floating around. Plus theyre helping reduce that old house smell. If youve got allergies or just strange smells in your home, these will help you breathe a bit better. I have to change them before 90 days, but my house is older and a few air gaps scattered about. Still a good value for the money, quality, and life span.

I use the 20x20” on the backside of a box fan in my garage for pulling dust out of the air and also neutralizing the smell of fumes when painting/varnishing. Works well. Installed in my aunts house and she is a 3 pack a day smoker and it helps cut down on odor.

Does pull odor out of an apartment. They are really very messy though as charcoal drops out of the filter each time you pick it up and move it. They are rather expensive for what they are in my opinion.

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

The filter contains lots of black particles about the size of coffee grounds. They tend to fall out if the filter is shaken. It doesnt seem as if the density of carbon particles is really sufficient to matter much.Theres lots of white space were air can pass through without contacting any carbon whatsoever. Plus, the path length that air has to travel through the filter is so short, that it doesnt give much opportunity for any odor causing compounds to bind to the carbon. In practice,I havent noticed much of a change in odor reduction with these compared to standard Filtrete filters even with the HVAC fan set to run continuously. But Ill probably keep buying them just in case they do.

Sounds good!

We have a wood stove and dogs in our house. This filter works great and was less expensive than all local stores

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