Today, 8/25, I was able to purchase a 6 pack of Filtrete 2200 MPR (14 MERV) on amazon for $84.99. In addition, Filtrete currently has a $12 mail in rebate when buying 4 or more filters. That's $72.99 out the door for 6.

I have heard that 3M tests filters at 500 feet per minute of air, while Nordic Pure tests them at 300 feet per minute, which makes them perform better on the test.shagbarkhttps://www.blogger.com/profile/07759080646499030919noreply@blogger.com
