Humidifier experiences?

Hi all,
For next winter, I am considering buying a humidifier for the bedroom. Of course, since this would be a piece of electronics running in the bedroom, there could be ES concerns with various technologies. For example, warm mist implies that some amount of wattage is used to heat the water, which could cause problems. Or "ultrasonic" humidifiers could cause problems due to the ultrasonic technology. Or something that has a fan running all night, well then you've got RF noise from the fan motor being dumped onto the power lines. So that said, does anyone have good/bad/indifferent experiences to report (ES-wise) for bedroom humidifiers? Thanks, Marc |

Thanks, Marc I had a pifco one and soon after setting it up it went rapidly back in the box, it was an ultrasound one, and gave off all manner of emissions. Aeriating fan type ones would probably be better, perhaps a 12volt model is available. Paul uk [Non-text portions of this message have been removed] |

A good AC motor is probably preferable to a DC motor.Shaded pole motors are
good, and condenser motors may also be good. Except with shaded pole you have to avoid the open-frame or c-frame type. The old kind with just a heating element could be fine if the heating element is not a big loop. I've heard of people bending the heating elements in hot water heaters, but I suppose there's a risk you could create a hazard doing it?

Bill, I think you mentioned this once before, that is, an AC motor is generally preferable to a DC motor; I'm not sure if you said why, though. Why is it the case? I thought DC was better than AC, period...

DC is better if it stays DC. But the only true DC motors are nanowires
and bacterial flagellar motors. Traditional DC motors used brushes to essentially convert to AC, and brushes are noisy, so it's bad AC. New brushless motors sound good, but they use a chip to convert to AC. If they had a real good chip with filters it might be fine, but that's unlikely. On the other hand, if you have really dirty power, you're better off with the above DC options compared to an open-frame (or C-frame) motor. But a good motor on clean AC will not make RF and the field will drop off quite fast. I think 3-phase motors might be very good but not an option with household power in the USA.

-I had a humidifier in my sons room when he was young I had too many issuesof shocking him more often. I had to take it out of the house completely. Some one told me to run a hot shower at night before you go to bed that seemed to help him more then the humidifier. He had really bad asthma when he was little and needed the humidifier but I could not hold him with out shocking him! That was my personal experience with a humidifier.

Hi, Marc,
What kind of heat do you have? Electric-forced air, hot water.... I have tried electric humidifiers of all sorts and hated every one. (I generally end up sick after several months, because they are hard to really keep clean.) Instead I make my own "humidifiers". No fan, no electric. Use you imagination. Here are some ideas I have used in various houses depending on what was available.... a large pretty glass bowl or basin of water on top of a radiator or in front of a heat vent. When the water ran low, (it held a at least a gallon of water but went thru at least a quart of water--on a rad, even more--every day), I washed it by hand or in the dishwasher and filled another bowl and exchanged them back and forth. In another room, I kept a quilt rack with large damp towels on it in front of a vent or dried some towels I had just washed on it. If I was expecting company, I took the front towel off and replaced it with a pretty quilt. If the look of drying towels bothers you, tho, you could use it like this all the time. I use a caldron (an old-timey looking cast iron pot), in my current house, on the vent of a floor furnace. The floor furnace is very hot, so the water steeps out--puts about 2 gallons of water into the air/day when it is really cold. And I clean this about twice a week. If you use a fireplace, that is another good place to place a caldron--looks like decoration. Some ideas incase you wanna go low tech, ;) Diane --- On Thu, 4/2/09, Marc Martin <[hidden email]> wrote: From: Marc Martin <[hidden email]> Subject: [eSens] Humidifier experiences?

Aha! Thanks, Bill. God, it seems you just can't win, until they start to design things better from the ground up.

I should have said that a small DC motor is probably safe (for me) beyond
6 feet, while a C-frame AC motor even with clean power might be an issue (for long term exposure) at 9 or 10 feet. It would be nice to have a motor based on the bacterial one...
