Honeywell Quick Steam Warm Moisture Humidifier

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.

Of four units that were sent, three failed after one or two nights'' use. Don''t bother.

Unfortunately, my experience was the same as most other reviewers. I only got two months use out of the unit before it stopped working completely: no mist, lights or power. Honeywell makes wonderful humidifiers, but this model is a complete dud.

I have a couple of tips for other unfortunate souls who are about to return this horrible humidifier. A rep from KAZ told me to send the unit in to their Return Department and they would replace it at no cost (although I have to pay for the shipping to KAZ). If you''re returning one of these units, be sure to tell the rep to do the following: waive the $10 warranty fee, and send a different model of humidifier as a replacement. The rep I spoke to had no problem with either of these requests. Now, I''ll just have to wait and see if they follow-thru on a good replacement.

I have a newer model, 3 gallon, HMWM-331. After going through 3 other brands with very poor results this season, this one is a winner! Very quiet (no gurgling); it will not disturb an infant or a light sleeper, as opposed to the Bionaire and others, efficient and easy to clean. So far, no mineral build-up, even though our water is quite hard. It uses disposable mineral absorption pads. The only inconvenience is filling the tankit doesn''t sit flat and you need to support at an angle. but that is really minor, given the quiet efficient operation and attractive design. Low price too. This is the best we''ve ever had. The phone support is also good. Kaz works for many brands and they are quite responsive, even though many of the brands aren''t very good. I definitely recommend this unit to anyone looking for a very quiet warm mist unit for a mid-size room.

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.
