Product review (2 stars): Was a little too short in length
As stated in another review, although this states it is a MAF-2 filter and an "Emerson MoistAir" brand in its title, it is about 1-1/2 to 2 inches too short for my Essick (was bought-out by Emerson) MoistAir humidifier. I was able to get it in the slots and carefully put the top on but the one end does not make it into the "final bracket" that is sort of important for holding it in place. I will be using a different supplier for my next filter to see how theirs fit. The replacement filter I bought at Lowes which is where I bought the humidifier sold ones that fit but had some sort of felt covering on one side. Anyways, it seemed to not last nearly as long as a regular filter so I am on the search for one that fits.
