Prevent Mold Growth by Airing and Heating

In wintertime, the humidity provides an ideal breeding ground for mold due to improper heating, high humidity and lack of ventilation. Read our short manual and learn how to secure your home from the fungi everyone dreads.

Showering, washing dishes, cooking - all of these activities increase the humidity rate, but even breathing maintains some degree of humidity in the air. In fact, one person creates between 30 -100 ml of water vapor per hour. It is, therefore, recommended to air the room several times daily for at least five minutes at a time. When there’s too little heating or ventilation in the apartment, moisture condenses in the coldest places of the houses, and mold is being formed. 

Prevent mold

The window areas are particularly vulnerable to mold. The majority of condensation accumulates on window panes and their surroundings. Mold likes to settle in damp areas. Once it finds a breeding ground, it spreads quickly.

One certain way to prevent mold is to keep the moisture in the rooms as low as possible. Although it’s a big fan of the living room, mold likes everywhere damp. As showering or cooking create large amounts of steam, it’s best to air the bathroom and kitchen as often as possible. Mold can also be prevented with exhaust systems via stove or bath. It is also recommended to remove moisture that has already been condensed.

Proper ventilation against mold and well-being

The most common cause of mold growth is inadequate ventilation. When there’s no fresh air, the windows and walls accumulate most of the moist. Ventilation all of the rooms regularly is the ideal solution to that problem. Fresh air is also good for your energy levels and overall wellbeing, so it’s a win-win situation!

So lüftet man richtig

The colder it is outside, the more moisture you can be let out while airing. Carry out blast ventilation sessions regularly (at least two to three times a day) and make sure to open the windows wide.            

Long-term ventilation is not advisable, as it allows the rooms to cool down. The same applies to keeping the windows halfway open which not only limits the air exchange but also requires the heaters to work harder.

Prevent mold with proper heating

Mold is best avoided with proper heating. The apartment should be heated entirely. Otherwise, the colder areas could accumulate humidity.

The average room temperature should be 20 ° C. 17 ° C is enough in rooms you don’t use as frequently. In the bathroom, 21 ° C is recommended. Under no circumstances should you leave the heater completely shut down while away. Cold rooms and walls heat up slower. Keeping a minimum room temperature saves energy and prevents the water vapor from condensing in the air at the cold spots.
