3M Filtrete Pleated Air Filter - Basic - 20-in x 20-in - 2-Pack - 100 MPR is rated
Rated 5 out of
I purchased these furnace filters last month. They were a stock item and next 2 day delivery through Purolator. This is my second order for these filters. I have 2 20” box fans. I attach one filter to the back of the fans. This has prevented dust and dirt from entering the fan blades and motor. My fans are are 2 years old but look like brand new because of these filters.
