Humidifier with electronics in room

Zodiac 1,777 792 September 9, 2010 at 05:12 PM
I think the air in my room has been getting really dry over the past few weeks to the point where I was waking up with a dry throat/mouth (even after periodically drinking water at night). It has gotten to the point where I was thinking of getting a humidifier in my room.

The thing is, I have my laptop that is occasionally running along with my internet modem and a router, and my tv and printer in the room as well.

My question is, will the humidity potentially ruin anything or have any potential to cause problems in the electronics?

What level of humidity are electronics built to withstand?

Thanks for any help.

I think most manufacturers recommend 70% or so max humidity level.

you should be okay running 1 humidifier in the room, just dont place it right next to your computer and electronics.

There's no prolem as long as the air remains at least a few degrees above the dew point. If you have a VCR, turn it on, and if its dew sensor warning light comes on, back off on the humidity.

One problem with humidifiers is calcium dust when hard water is used, and this is most visible on static-charged surfaces, such as old CRTs without the anti-static coating and that crackle when you place your hand near the screen. Calcium dust can hurt optical disk drives.

That's what my semi-successful Google search results told me.

Yeah, just running one and its at least halfway across the room from all the electronics.

For the most part the dew point is pretty low here so that shouldn't be a big deal but I don't have any big electronics such as old CRT's, only a flat screen tv and a laptop.

Thanks for the replies.

Sorry, I meant an old CRT can be used for checking for the presense of minerals in the humidifier's water supply -- if you don't see calcium dust on the screen, then you don't have to worry about your optical drives getting contaiminated.

Get a thermometer with hygrometer and monitor the levels. Cheap analogs for $4 or digitals for $10.

55-60% relative humidity is comfortable for me and all my electronics and helps neutralize static electricity. No shocks and no clingy dust at these levels..

I have also ran equipment for years in 85%+ conditions without problems.

Same as above, and another testimonial to make sure it isn't close to anything. This isn't electronics, but I had a pistol in a nightstand I placed a humidifier on. It only took 4 days before I realized what I did and there was already a fleck of rust on it. (Happy ending, some cleaner and light rubbing took it off) Moral of the story: Don't put your stuff close to it!
