Asthmatic tendencies, humidifierHoneywell HWM-910 quirks

[AndyHancock]

Humidification seems to be improving things. At first, I was boiling
water on the stove, and blowing it around with a fan. A hygrometer
helped me know when to do that. Unfortunately, the relative humidity
dropped significantly through the night (can't keep boiling water
while I sleep). After much reading, I settled on a humidifer,
Honeywell's HWM-910: http://tinyurl.com/yckrk5t. So far so good, with
the following exceptions.

1. The brown water at the bottom of the tray is certainly not slime or
sludge, as it developed in 8 hours. It was pretty obvious looking at
the metalic heating element that there were rust spots. Depending on
where it was made, the metal material/alloy may have had some corners
cut in the mixing of materials.

2. The unit might be merrily steaming away, but it has turned off
inexplicably. The humidity setting was high, and the relative humidity
was only 30% (30-50 is good for humans). I have to press the Start
button to get it started, but this leaves open the possibility of
waking up to dry lungs and realizing that the unit turned off early in
the night.

Has anyone else tried this model and found the above? I'm still
trialing this unit, will post back if there is any interest.
