Poor design, premature failure

Clearly a lot of people have had problems with this unit. When mine failed after about 6 weeks of use, I dug into it to see what was up. It ends up that the overheat protection on this thing isn’t real great. The first layer of overheat protection is provided by a sensor integrated into the heating element. I can’t tell exactly, but it seems from the element manufacturer’s literature (….) that the device sends a cut off signal between 250 and 300 C, per the chart on page 4. However, Honeywell used an NEC-Schott SF214E thermal cutoff as a backup device. This fails permanently if it’s heated to 214 C. In other words, the backup, “sacrifice the machine and not the house it’s in” device fails before the normal operation re-settable thermal cutoff. As a result, the device will probably stop working the first time it runs dry. Don’t buy it.

Update (2/21/2012): This item is currently on sale here for the lowest price I’ve seen.

A good product, but suffers from a fatal flaw
I bought a new Honeywell Quicksteam (HWM-330) several months ago from a local store, to help keep our bedroom at a comfortable humidity. The humidifier worked well enough, but less than a week after we had been using it, the unit wouldn’t turn on again the morning after we used it.

We suspected the problem was that the unit burned out after having used up its water supply during the night. To their credit, Honeywell sent us a brand new unit after we sent the broken one back to them. But once again, the new unit died after running out of water overnight, less than a week after we had received our second unit.

It would be one thing if they had advertised the unit as NOT having an auto shut-off feature. In that case, we never would have purchased it; however, we’ve had two units die after less than two weeks of CUMULATIVE use, and for the same reason. As such, I strongly recommend AGAINST purchasing this humidifier.

Three of four units defective
Of the four units have been cleverly, not three to one or two nights. Do not worry.
