The Honeywell Cool Moisture Humidifier quietly provides natural relief from dry air. 30% quieter than comparable units, it is ideal for bedrooms and living rooms. The ProTec antimicrobial treatment helps prevent the growth and migration of mold, fungus, algae and odor causing bacteria onto the filter.
I purchased this humidifier at the store about two months ago. It does a very poor job of maintaining desired humidity level in my medium size room, the highest level ever achieved was 32% (set at 55%). The filter holds 2 week max before starting emitting horrible moldy odor (owner's manual says it should be replaced about once during a season), I am on my 4th filter and 4th demineralization cartridge already. The only advantage - the room temperature is a little higher when it is working.
