Product review (5 stars): Essick Filter Frame
Due to my stupidity, I had thrown this away the first time I was cleaning out my Essick humidifier and changing the filter.  I was extremely pleased to find this on Amazon as the humidifier would have been unusable without it in place.  Glad to say the frame works perfectly.  Item was received quickly and works exactly as needed.  Hopefully I won't be needing another one of these anytime soon...
