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

They were packaged with a large bag of dog food so they got squished a little. Also they got rained on and fell pretty soggy. Not going to send them back or anything. Ill make it work

really good for filtering out pollens and dust; easy to install, too!

Definitely notice a difference since switching to these! House feels/smells cleaner.

These were too restrictive and caused the condenser to bang each time the air conditioning shut off. I want be buying again.

The filter is good and quality is there but it did not make a noticeable difference with odor removal vs. other 3M filters.

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!

Made the air smell great.. Wish they were cheaper tho.

odor reduction

I gave 5 star for this review because the question, but the filters have an odor that is put off. This is from the charcoal

With 3 dogs in my house these filters are a life (or nose) saver!
