Product review (5 stars): Works in Sunbeam Cool Mist Humidifyer
Worked just fine in my Sunbeam cool mist humidifier that called for Filter B. It doesn't have the black meshing on it that the original one did so I was hesitant to purchase, but now a non-issue. I thought I might need to cut a 1/4" off it to fit but once it got wet, it fit fine.
