questionshumidifiers...good or bad for home electronics…


from what i understand, any kind of moisture is bad for electronics.

that said, we've used a humidifier in our family room (where the electronics live) for years and never had any issues. just don't put the humidifier close to your gear. also, we just bought a cool air humidifier for the baby's room. something about not wanting to increase the temperature in the room.

quick run down on the difference (from eHow):


@carl669: its a smaller room so im wondering. Ive also heard that any moisture is bad.

thanks for the link


@notoriouscheech: i'd say if you're only going to run it occasionally, you'll be fine. electronics are mostly made to stand up to normal humidity levels. now, if you want it to feel like you're in rain forest, you might run in to issues.


If you're only running it in the winter, chances are it's not going to be much more humid than even air conditioned air in the summer or opening the window in early fall.

A lot of electronics say right in their manual what range of humidity they will function in. Condensation is a much bigger problem than humidity itself. If you take something electronic inside after being out in the cold for a while (like a digital camera), leave it off until it has time to dry out. As soon as you come inside, there will be water condensing inside right on the electronics. If you turn it on too soon, you might short something out.


I think humidifiers would be pretty bad for electronics. I know they're good for acoustic guitars because they keep moisture in the air, preventing the wood from bowing. Moisture + electronics = bad time.

Curious, why do you think you need humidifiers in your home?


There are different types of humidifiers. There are the kind that eject a visible mist into the room and the kind that does increase the humidity by blowing the evaporating water (vapors) into the room. The mister separates the water into smaller particles (the mist) and blows it into the room. This will get the room cooler and more humid. The evaporating humidifier has a sponge-like filter and a fan that blows the evaporating water into the room. I prefer the evaporating type.

I've had both and neither affects electronics. A word of warning - it's best to have good circulation in the room in question or you can develop a mold problem with the increased humidity.


Prior to turning on your humidifiers, you should blow all the dust out of your gear. Dust will absorb moisture, and could cause you problems later.

As to the humidity itself, your gear should be fine at 50% rh. A lot higher, and condensation may be a problem. A lot lower, and static electricity becomes your concern.


Good question. I use one sometimes during the winter as I live in a very arid area (under 20% March through June) and my skin gets painfully dry and itchy. The dry air can also cause nosebleeds and exacerbate sinus problems. The first thing the doctor recommends for cold and flu around here is a humidifier. But I never thought about how it might affect electronics. In this climate it might actually even be helpful, as we have a problem with plastics becoming prematurely brittle.
