Review on FilterBuy 20X20X1 Pleated Furnace Filters by Kobby Cagle

While they are sold at a great price I'm not sure they work as well as the 3M filters I have used before. They look as gnarly at 3 weeks (not even a full month as they should) as my 3Ms would look at 2 months. And despite the fact that they're supposed to purge all sorts of pollutants from the air, using them has escalated my allergies more than ever. I have this set up for recurring shipping but I will be canceling and going back to my more expensive but much better brand of 3M. *Note: The image comparison only applies to this filter, not to the 3M comparison. The picture shows how this filter looks new after 3 weeks.*
