My Essick Air MA1201 humidifier runs continuously, and only the bottom half of the filter is wet - it's not wicking up at all. Is this normal, or is something set up incorrectly?

Do you have tried to use without filter?

Those filters don't last forever! Whenever I had that problem, I just replaced the filter. (The fresh filters also contain some kind of anti-bacterial or anti-fungal, since you're not supposed to add anything to the water which would spray into the air.) My problem has been finding new filters--does Sears still carry them? (The small one I was in recently does NOT.)

I would suggest turning up the humidistat (usually located on the the return air duct to a higher setting and listening for a "click" noise on the supply valve. If you do hear a click but dont see / hear any water than the culprit is likely the valve itself.

sounds like you may have it wired to a continuous power source vs one that shuts off with the furnace. The most common wiring is red to C & white to W

If you are using large amounts of water and it is not leaking anywhere than I would be inclined to think that your humidity indicator is not correct. Do you notice any differences since you have been using it,such as less static electricity,skin and hair not as dry as usual or house plants looking better if you have any. Also not knowing what area you live in I don't have any idea what your normal atmospheric temperature or humidity are. Other factors to consider is how well your house is insulated,number of doors and windows and how many times doors are opened. Without knowing these things your humidifier may be doing all it can. Hope this is of some help.Thank
