Unpleasnt odor Noticed a odor (musty smell) and remembered to replace filter. Did that today and after turning back on, smell returned . Once again -only when on. Thanks Rich Deuter [email protected]

Yes thats how it works If you think the flow is too fast turn down the flow , with the valve on the water line .

If it smells like plastic burning. Stop using it immediately. As there could be an electrical short or overheating of the unit. If doesn't smell like plastic burning, you'll need to be more descriptive of what the odor smells like.

I have the same poblem with mine. I'm telling you it was the brand new filter...after about a day the odor would start. I washed the filter out with white vinegar, then a drop or two of Dawn in hot water, then rinsed in cool water. Worked fine so far. It's been about a week. good luck

Hope this helps, check and see if humidistat is set to 35% humidity and that bypass damper on humidifier is in the open position or winter position.(humidistat is usually located on cold air return duct near furnace). Next, replace humidifier media pad, remember to replace media pad (filter) annually, you also may want to clean any lime deposit out of humidifier housing with a solution of warm water and white vinegar before installing your new media filter.Remember to turn power off at side of furnace when cleaning humidifier and replacing media. Before installing new media turn power back on to furnace, set humidistat to the on position, turn furnace thermostat above room temp., and inspect humidifier to see if water is running from top,(you may want to have a bucket under humidifier when checking for water), if you see water running, turn power back off to furnace, properly install new media filter, reconnect humidifier cover & set humidistat to 35%. If you do not see water present, check water supply valve to humidifier and make sure its turned on. If water supply valve is open, then check water supply tubing for blockage.And the last things to check is to make sure all registers through out your home are open and not blocked by any objects, also make sure furnace filter is cleaned, if none of this works refer to installation manual to see if humidifier was sized and installed properly, Good luck.

pour 1/4 cup of bleach into the collection resevoir.

I would say that the beauty of steam is that it has to get through the 100 degree temperature to leave the aqueous state - i.e. to move from a liquid to a gas.

The benefit of that is that any organizums in the water should be killed as a result of that process. Its possible that it smelt musty or old stagnant water smells but to be honest there is little change of harm to the little ones.

Best wishes

First, clean or replace the filter. Next, mix a very weak solution (40:1 ratio) of bleach and water to fill the unit. the bleach will kill any bacteria that could be causing the odor, but NOT harm anyone, The filter will take care of any hard water issues. Just don't make the mistake of thinking "If a weak solution is good, a strong one is better". NOT TRUE. Stay with the 40:1 mix unless you like breathing bleach. (Yuk) Note: It may take a couple of days for the odor to go away.

I just bought one as well. It has a terrible odor! I wanted to let it run for a while, but now I think I won't waste my time. Thanks for the posts.

First of all the white build up is hard water residue. If you haven't replaced the filter in 3 and a half years you NEED to replace it. They have a safety switch may not be satisfied because of your filter.

Odors are common because water stagnates in the tank. 1) Unplug the unit. 2) Empty the reservoir, mop up any damp areas, and clean the tank and evaporator belt with a mixture of one gallon water. Add 2 tablespoons of chlorine bleach to the water for stubborn smells.
