Product review (5 stars): Fits my HE300A
Fits fine my Honeywell HE300 humidifier even though this model is not in the description here, or on the package. My HE300 manual says that this model, as well as HE250 and HE200, take this pad, and it did fit. (The pad packaging lists these Honeywell models: HE260, HE265, HE360, HE365)
