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

These work great, very free flowing and add a freshness to air.

If you have allergies like me, these are a lifesaver. I change my filters every two to three months depending on the season to keep my allergies in check.

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.

Must have for allergies and Vocs! These are really well priced for the versatility they deliver. Thanks 3M for thinking outside the box and creating versatility while helping people stay healthy!

Great filters, not a great price

Great filter for animal owners

Great quality, great price, fast shipping (if you have prime)... cant beat it.
