Condesation issues

[Mike Oxlong]

Packet looks something like that, it is called Ketsu-Ro hou-shi (means prevent) shi-to (for "sheets" type) OR Ketsu-Ro kyu-shu (absorb) te-pu (for tape type), "Ketsu-Ro" means the condensation.

Pictures all copied from Tokyu Hands online shop, and stocks are still available online, so your trip there should be a productive one.

You must spread some Reputation around before giving it to tidbits again.

Edit: sorry, should be Bou-Shi for the word "prevention" instead of "hou-shi"

Stock availability in Tokyu hands are Location sensitive. For Tokyo the one mated with the train station (Shinjuku) and the one in Ginza might not be the best. Shibuya being immense, their might be more choices...

(Don't know aboot Ikebukuro, is this one new ?)

Mrs Tidbits - You are a legend.

Thank you my friend.

I have found that a cheap, useful way of removing condensation is seeing that my wife as an adequate supply of dry towels to use....

Also, GomiGirl, since you have a baby you should not be using a dehumidifier during the Winter as I think I read in this thread. You should be adding humidity, not taking it out in the Winter.

The electric heaters dry out the air to below desert-level humidity and that's bad on nasal passages and skin. Plus, viruses, bacteria, mold growth, respiratory infections are reduced by keeping the humidity in your place between 40-50%.

That's why people keep water pots on top of kerosene heaters, to add more water to the air.

Those air ionizing air cleaners you see in the denki stores work very well. Most have a function to add moisture to the air and they aren't a gimmick.

SIDENOTE:

Somebody got a wabsite for local twinpane windows maker ?

Toyokawa Eiden is selling them.

Damn... I have to get my vaccine booster shots and cross the river...

If you have condensation issues you likely have too much moisture. In this case we learned it's in the 40-50% range which is on the high side for winter, but not completely unreasonable. Mold and milldew isn't a healthy addition to indoor air. People using unvented kerosene heaters indoors are filling their apartments with carbon monoxide and fine particle pollution (among other things) so I would not look to them as role models.

I would be very skeptical of ionizing air cleaners as some are mere ozone generators which add a potent pollutant (ozone- o3) to indoor air under the guise of cleaning the air. (see http://www.epa.gov/iaq/pubs/ozonegen.html) I don't know if this is what's being sold but don't think an air filter will address any of the issues raised in this thread.

I think the plastic sheet solution makes sense to prevent condensation.

No, it's caused by the dew point from the weak temperature insulation of the single pane glass. The bottom of the glass is colder than the top, that's why the moisture condenses near the bottom as the indoor air meets the inside of the glass surface.

You can add a fan to the bottom of the windows or heat to raise the dew point (that's how anti-fogging bathroom mirrors work) or you could spray a high viscosity material over a smooth (clean) surface to eliminate points of condensation (that how anti-fogging car windshield sprays work).

Mildew doesn't exist until well above 50% RH.

50% is the ideal if you'd like to reduce mites, bacteria, viruses and molds.

Japanese negative ion air cleaners don't generate ozone.

Ozone at low doze is a potent air cleaner that can be used to kill mold, there are diy and commercial device for this, I think it also kills bad odors. But like everything... too much is bad...
Now for the humidity concentration, Usually between 40 to 70 is considered normal range, comfort zone for hoomans being around 50-60.

40 is the minimal comfort zone for living things. For electronics, below 30 you are gambling, around 20 it's time to shutdown everything. Server rooms don't have just aircooling, they need climate control because cool is good but dry is death, computers know to slow down by themselves when they overheat but don't have the luxury of humidity alarm.

Can we get an update on what actually worked??

I'm having trouble with heavy condensation and want to know what product actually works!

Despite my participation in this thread, I've only ever accomplished increasing wetness. You're gonna need to get Jack or McToeJam up in here to teach you how to keep it dry...

40% RH is around the top end of what you can have in a place with an actual winter without having moisture problems. Humans are versatile creatures and can be quite comfortable between 30 and 70 RH or so.

My house is in the mid 20% range for RH which is on the dry side but it's a relatively drafty place. I just got back from the mountains of Colorado which was way drier than this! My laptops, TVs, etc are just fine and live nice long lives. The only issue I see with low humidity is electrostatic discharge but that's probably more a problem for servers than a home. If your servers are cool but humid they may suffer from corrosion and condensation, which are also death.

I would never generate ozone in an indoor area on purpose. See the EPA link I posted above for why. If you want to filter air, buy an air filter, but don't expect it to clean the whole house's air.

My son and wife both have fucked ears, so when it is really dry or humid, it causes them ear aches, infections, etc.

We went through numerous devices that make the room more dry or humid, machines that did both, either or, and even went to expensive medical equipment... None of that work and cause days of pain to my lil boy...

What worked for us was hanging laundry to dry in the room that when it was dry and hanging towels, sheets, etc. in the room when it was humid... no BS on this, if we don't do this my boy wakes up crying and holding his left ear...

we put our humidity sensor on the opposite side of the room from the laundry to do a test on if it really worked and it did.

It is really hard to make a humid room dry... we dont use the dry setting onhe aircon cause that just fucks up my wife's and son's ears even more... but hanging sheets hear and there helped a bit. good thing was that the kids loved it cause the used it as a train station, tunnels, and bunker when chucking legos at each other...

Regarding condensation on the windows, this was really hard for us to negate... we have double pane windows (to keep the sound down from them damn yaks in vans w/ loud speakers...) so we have to wipe the windows down every morning and night before we sleep.
