Product review (5 stars): What a Deal!
Went looking for the filter that would fit my General humidifier.  Could not find it in the local stores (i.e., Home Depot, ACO).  Could only get it from the HVAC supplier which I wanted to avoid since I didn't want to have to pay a markup.  So I searched the world via the Internet to see what I could find and wow what a deal!  This filter costs 3 times less than going through my HVAC supplier.  Keep in mind, this humidifier and brand have been around forever so I was glad to see that I didn't have to spend alot of money on this simple maintenance item.  I only ordered one since I wanted to make sure it really was the correct part.  It was!  It was not some imitation (copy) part like another supplier offered.
