Honeywell HCM-630

The humidifier does run quietly. It comes apart easily for cleaning - three pieces to be exact. The only drawback with this humidifier is the humidistat. It's mounted above the motor that gets warm after… running for a while. After turning off, the warmth of the motor prematurely turns the humidifier back on making the room more humid. They should have isolated the humidistat from the motor and have it ventilated to the outside. I have a Slant/Fin GF-300 warm mist humidifier that has the same problem (till I removed the humidistat entirely from the case). Now it's working far more accurately with the humidistat installed in it's own ventilate box, wired up with a male plug (plugged into an outlet) and a female outlet to plug in the warm mist humidifier into. Will have to purchase a separate humidistat & have this Honeywell HCM-630 plugged into it for more precise humidity control. Otherwise it runs very well and quietly. I only use the lower speed as it's more quiet and uses less energy.

Due to my wife's allergies and sinus problems, we run a humidifier every night, year round. This is my first HCM-630, which I got about six months ago, after using two other HCM-645s. They've lasted between… one and two years before the motor goes out. The HCM-630 has a smaller tank, so is not as heavy to fill. Both types required daily filling. There is definitely a technique involved in filling either tank. The plastic base of the HCM-645 was a little easier to clean than the 630. I need to sleep with some "white noise," so I don't find either model "noisy."
