Kenmore 10 gal. Contemporary Humidifier —
I have used this humidifier in our home for the past three years. It counteracts the drying of the indoor air by our forced-air furnace, and in part helps with stopping dry mucous membranes, etc. and encouraging resistance to colds.
I chose this model for our 1600 sq. ft. house because I wanted a humidifier I could run full-time, and NOT have to listen to a lot of noise from the unit. I can run this unit on LOW all day and night, and it is very quiet. Much quieter even than the heater is.
Earlier I had a small model, but had to run it on high - and frequently was irritated with the noise.
This unit does put 10 gallons or more of water into the air in our home (Southern California) every 12-24 hours. Refilling it is a fairly easy task. And one filter can last at least three months or more. We seem to use 2 filters for a full winter period of time.
In summer I clean it out and store it for next year.
The unit also has the option to set the humidity level you want. Then it automatically turns off when it gets to that level.
All in all, what I consider a perfect home humidifer!
