Dry indoor air: how to finally get rid of it
Dry indoor air: how to finally get rid of it.
In winter, the heating is on and the air gets dry. Here you'll find out how to recognize it, how to measure it and what really helps. No miracle cures, just seven measures you can implement today.
Cold air can hold very little water.
Cold outdoor air contains very little moisture. When it enters the house and is heated, the relative humidity drops significantly. The warmer you heat, the drier the air in the room becomes.
Crackling and sparks
Sweaters crackle, door handles give a little shock. Static charge is more common in dry air.
Brown leaf tips
Houseplants, especially those from tropical regions, get dry, brown tips.
Wood reacts
Parquet gets gaps, wooden furniture and instruments react to very dry air.
A hygrometer costs very little and ends the guesswork.
A simple hygrometer shows you the relative humidity. For living spaces, 40 to 60 % is generally considered comfortable. Measure in the room where you spend the most time, and not directly next to the heater.
- Below 40 %: rather dry, the measures below help.
- 40 to 60 %: just right, do nothing.
- Above 60 %: rather too damp. Then ventilate instead of humidifying, otherwise the risk of mold increases.
What really helps.
-
Ventilate briefly and thoroughly
Open the windows wide for a few minutes two to three times a day instead of leaving them permanently ajar. This prevents walls and furniture from cooling out.
-
Heat one degree less
Every degree less lets the relative humidity rise slightly. It can be cooler in the bedroom.
-
Dry laundry indoors, in moderation
A drying rack releases a lot of moisture. Only in rooms that you ventilate afterwards, and not when the hygrometer already shows over 60 %.
-
Group plants
Plants release water into the air through their leaves. Several plants together create a small, more humid climate. Be careful with cats: only choose non-toxic plants.
-
Let water evaporate openly
A bowl of water or an evaporator near the heater continuously releases some moisture. Change the water regularly.
-
Moving water in the room
A room fountain or a water wall lets water flow over stone. A part of it evaporates. How much depends on the water surface, room size and temperature.
-
Keep it clean
Whether bowl, fountain or humidifier: change the water regularly and clean the containers. Otherwise, standing water quickly becomes unappealing.
What a fountain can and cannot do.
A fountain can
- continuously release some water into the room air, without mist and without the noise of a device.
- with a large water surface, like with a water wall, evaporate noticeably more than a small tabletop fountain.
- at the same time be a beautiful object that you like to look at and listen to.
A fountain cannot
- replace an electric humidifier in a large, heavily heated room.
- promise you a fixed percentage. We do not measure for you and therefore do not state any values.
- run without maintenance: refilling the water and changing it regularly is part of it.
