Product review (5 stars): Better price point for the OEM
I read a variety of reviews here, trying to find the OEM for my Carrier mechanical air cleaner.  I saw some comments that this is not as described, and I completely disagree.  This is as OEM as it gets.  It appears to be in the same packaging as what I purchased from the local Carrier dealer, but at a much more acceptable price point.  There is a learning curve with getting this into the accordian style frame, but I did my swearing last year when I replaced it, figuring out a pretty foolproof technique for getting it in on the first try in just a few minutes in that process, so this time it was a breeze.
