Lasted only a few seasons and became inoperable due to leaks and very poorly designed electronics, very clumsy unit to handle and set up.

I’ve been bragging about my humidifier for a while, just love it. However, some of the issues I see others are having seem to come from the fact that this humidifier does seem to have some design issues that can make it hard to use if you’re not techie at all. For example, the terminals on top of the base that contact the switch part of the unit need to stay dry. If you get them wet when cleaning the unit, it won’t turn on until the base dries out. Be careful when cleaning not to get the terminals wet! Also, make sure the unit is sitting on a flat surface, no tilting as this may cause leaking. I suspect that some may be putting their units on floors that are less than flat, causing the leakage. Also, when setting up the unit, set the base on the floor (or wherever you want it) first without water, then put the water reservoir on the unit…no leaking.
As far as cleaning, every week or so, take out the pad and drop it into some white vinegar with a few drops of bleach to disinfect and dissolve any mineral buildup. You can get many uses out of a single pad this way. Clean the unit with the same solution and the reservoir with a little bleach to disinfect that too. Watch those terminals! Keep them dry. When you put the unit back together make sure everything is seated well. If it doesn’t turn on right away you might just need to jiggle the front a bit or press down to re-seat it properly. If you got the terminals wet, let the unit dry out.
With a little care this is a fine unit!

My humidifier worked for a season, then started leaking all over the place. I would not recommend.

Worked great for about 4 weeks. One day the refill light would not shut off, so I cleaned it, thinking it was about time. Inside, I found that the filter pad had disintegrated to a disgusting brown mush, and the plate had melted one side of the plastic housing, and half the plate was covered by an almost un-removable layer of minerals. We have pretty soft water here, so this is extreme. I suspect the problem is in the wiring or sensors since nothing I do appears to help.
One review I saw somewhere when I was looking for answers said that hers works fine if she rinses the filter pad out once a week. This is supposed to replace that old HMW2030?? That machine could go at least 6-8 weeks without cleaning and never needed a single filter or pad. I have one that is still going strong.
Many reviews I saw complained about the machine breaking after a short time (if only I had read them before buying). I would not recommend the 330 to anyone.
So now what? Honeywell does make a model that is much better: the DWM250. The tank is smaller, but the heating element is solid and positioned from above. It is the same innards as the 3-gallon version which I have used for years, and still use and love. I wish they would make that again, but in the meantime the smaller version does the job for me

Although this machine delivers an adequate amount of humidity as needed, its thermal overload protective device failed, leaving the machine inoperable. This is an unacceptable design flaw. Don’t buy it.
