ᐅ 60-65% Humidity in Living Room and Open-Plan Kitchen – Experiences

Hello everyone,

Here’s the situation:
Last Friday, I noticed two "large" (~5cm x ~5cm (2 inches x 2 inches)) spots in the corners of one side of the living room, which I don’t use very much at the moment. An emergency service came, but they couldn’t find a real cause. They told me to heat and ventilate.

So far, so good. I bought a hygrometer and was concerned because the values were around 60-65%. A building technician came and checked the walls with a moisture meter, but it didn’t seem to be wet; he didn’t say much more on the matter. The corner is apparently dry again now. From the outside, everything seems fine as well.

The house was built in 1950.

Now I have to admit, I had very little (or almost no) ventilation recently, and I also didn’t heat much, which I am now catching up on. I am using shock ventilation (rapid ventilation), including cross ventilation (the doors are removed, allowing for direct airflow) for at least 5-10 minutes. Morning, afternoon, evening.

Example: Today at 6:25 AM, 21°C (70°F) at about 61% humidity. Shock ventilated with cross ventilation: dropped to ~18°C (64°F) and 47%. Windows closed, had breakfast, checked again: 51% at about 20°C (68°F).

I keep the rooms, as much as possible, consistently between 20-22°C (68-72°F).

Can I improve anything? Should I be worried? This is my first apartment, and I’m feeling a bit nervous right now. I definitely don’t want mold and I know I have neglected things for a long time (over several months). A certain panic is rising in my mind now.

Best regards

Lately, I hardly ventilated at all and didn’t heat, but I am now catching up on heating.

Welcome to the forum,
please continue heating and ventilate regularly,
the spots should then dry out and decrease,
there is no need to panic, you have responded well

Thank goodness these are already dry... still, I’m a bit worried that I may have reacted too late.

It certainly takes some time for the relatively high moisture to gradually dissipate, right?

Yes, it will eventually stabilize at lower levels.

Hello everyone.

So far, it has not occurred again. The humidity has also decreased well and now stabilizes between 45-55% (depending on usage time). Thank you 🙂

Is it your property? If yes, you can install a decentralized ventilation system, allowing you to control the humidity level in your room.
