| | | Urgently wanted : a de humidifier in zurich
Hi,
I'm looking out for a de humidifier to put in my baby's room urgently ( she is suffering from dry nose and can hardly sleep at night :-(). Any one willing to sell right away please PM me ASAP.
Thanks,
Archi

Hello
You mean a Humidifier, right?
Many electronic shops are having a sale now.
Fust, M-electronics, etc.
I would propose you get one of those "unheated" ones which are using ultrasound to evaporise the water (cool mist) for your baby. These usually cost between 50-150chf. They have automatic settings.

are you sure you want a bacteria machine in your infant's room?
put a bowl of water underneath the cot instead. This will achieve the same.

When it is raining or snowing the air is very humid, you could just open the window once per hour for 3 minutes.

Another thing: turn down the heater because heating makes the air very dry.
Hope this helps. |

Agree: Bowl of water in room, wet towel on radiator, cut an onion and hang it over the bed ... All good remedies eg on holidays in an apt or hotel room.
However in Switzerland in Winter, especially with young kids, you really do need a humidifier in the long run. It's a good investment.
Humidifiers can be bought at all electronic outlets (also EKZ which is Kt Zurich electricity supplier) and good ones do not blow steam into the air, they have filters and clean the air as well. Priceless, we rarely get colds or infections since we installed a good one.
"Luftreiniger und Luftbefeuchten" are the german words for it (or similar - feel free to correct!).
You can also get a very cheap device to measure air temp and humidity and people as well as plants and furniture need between 40 - 60 % humidity. Hard to get without help in these well heated homes.
Coming from Oz we never needed humidifiers ...I learned a lot since being here,

Very cold weather, with many frosts, and with no precipitation, brings dry air.
You can see that today in Zurich it is 82% humidity, despite snowing for 24 hours http://www.bbc.co.uk/weather/2657896
You don't need a humidifier, if it is frosty outside just buy a large plastic bowl (LIDL are selling long plastic laundry washing baskets for CHF 6,99 this week) and put some warm water in it, or hang wet towels up. Open the windows for 3 minutes every hour, much healthier!

Humid when snowing? When did you get that from? Usually when it is cold the air is very dry.

Try and concentrate please, and learn something. Obviously you spent too long with the happy baccy!
Forecast for Zurich is above 70% humidity and cold, for rest of the week, which is wet weather. Hint, dry is less than 40% http://www.meteocentrale.ch/de/europ...ils/N-3518042/ Click on Detailvorhersage Look up Dewpoint on Wikipaedia

What you see in the weather forcast is the relative humidity which is (highly) dependent on temperature.
Simply put: If cold air even of high relative humidity is heated up (enters through your window), its relative humidity drops SIGNIFICANTLY!
You seem to be quite cynical for someone who does not even know BASIC physics! Smart@ss!

An explanation.
The humidity value quoted in the weather forecasts is the relative humidity, not absolute humidity. It is related to the temperature. Basically, the colder the air, the less moisture (water vapour) it can hold. Take 1m3 of air at 0°C. It can hold a maximum of x grams of water vapour. This will mean the relative (to temperature) humidity is 100%. The air is saturated and will not hold any more water vapour. Now bring this 1m3 of air inside, where it's temperature will increase to 20°C (say). This warmer air can hold much more water vapour (say five times) before it is saturated, but the actual quantity of water vapour within the air is the same. Therefore the relative humidity is only 20%
People like air to be warm and fairly humid (20°C, 35-50% RH); this is the comfort level and the only way to increase the humidity inside a house is to evaporate some (well, a lot, actually!) water into the air. And keep the windows closed.
We have a humidifier and it evaporates 6 litres of water a day into the air, which raises the relative humidity from 20% to 30% (at 23°C). And we have a heat recovery ventilation system with a system that prevents the water vapour escaping (enthalpy heat exchanger). When you consider that it takes such a large volume of water to slightly improve the humidity, you can see that placing a bowl of water in the room will not do anything noticable (except phsycologically).

Now, how about some advice?
I agree with above that just towels will not help. Constant ventilation (which is called here Komfortlüftung) brings down humidity a lot.
So get a high quality humidifier. Be careful: some are notorious for spreading bacteria! http://www.ktipp.ch/tests/testsieger...Luftbefeuchter
And some are quite loud as well.

I learnt this law at school in 1960, is it still valid professor? k = p.v.t and wasn't it called Boyle's law? http://en.wikipedia.org/wiki/Boyle%27s_law

Do you have radiators for heat? You could try a ceramic humidifier, just fill it up and hang it on the radiator, no need to plug it in. Similar to this. I have a neighbor that has a couple but I don't know where she got them from.
