I've been looking for WEEKS off and on for a good quality humidifier, hopefully one that isn't a drum spinning in stagnate water that can be filled from the TOP instead of having to carry heavy tanks and flipping them over. My MIL REALLY needs a humidifier, but she has osteoperosis so she cant carry these 2 gallon tanks. Even one gallon is pushing it to the limit. Any ideas??? Oh, and she's in an apt so she can't do the furnace humidifier.
