Cool Moisture Humidifier 

Great little machine. This is our second Honeywell Humidifier. Our last one ran nonstop for about four months at a time during our winters. This one has a built in fan but is fairly quiet and operates well.  Looking forward to the same great output that we got from our last one.

Water use 

The unit has been working real well. The area that I live in has very hard water. The old unit that  I had was not one with a filter.

It put white powder all over the house and started to ruin my electronic gear. So in order to use it  had to buy to buy distilled water which was a lot effort.hauling it home from the store.

With the Honeywell unit I am able to use the water out of the tap.

I like way its simple design is what I need to keep the humidity in my bedroom up to what is healthy.

Very nice.  A bit smaller than I anticipated and high speed is a bit noisy, but overall, a great humidifier.

Very easy to fill with water.
