Good morning everyone,
I have been living in my own home since June (maisonette apartment, 3 rooms, 70m2 (750 sq ft)). Although I ventilate frequently and wipe off the window condensation twice daily (I have already experienced this with fogged windows in my previous rental apartment, which was also newly built), the windows still fog up from the inside, especially at temperatures below 5°C (41°F).
The two Velux windows (kitchen, dressing room) are particularly affected. This morning, while cleaning, I noticed the first black "spots."
Is this already mold or just dirt that, combined with the condensation, looks like mold?
I look forward to your answers.

Then ventilate at least 3 times a day for 10-15 minutes each time, spread throughout the day (in the morning before you go to work, at midday after you come home, and in the evening before going to bed). Additionally, ventilate as needed (after cooking, after showering). Always do this with windows fully open. Keep an eye on the humidity level using a hygrometer. It should always be between 50 and 60%. If it rises above that, ventilate again immediately.
You should also heat the bedroom and dressing room. Otherwise, the air will not properly absorb the moisture.
Edit: @Musketier was faster 🙂

Okay, I’m extending the ventilation period to 10-15 minutes. I can’t specify the temperature exactly, as I’m heating on setting 2 out of 6.

Thanks for your reply. 🙂
What do you think about moisture absorbers based on granulate blocks?

I use a dehumidifier from Aktobis (WDH-520HB) in my basement. Its power consumption is lower than typical construction dryers, and it works well for me. However, I’m not sure if this device is powerful enough for your drying needs during construction. If in doubt, you might need to use several units.

Can I set up the device in my hallway, leave the doors to the other rooms open, and dehumidify centrally from one spot? Or is it better to dehumidify one room per day (living room, bathroom, bedroom)? I don’t want to buy several units for now.
