Good day,
I am new here and hope you can help me (even though I am not currently building myself):
We recently moved into a newly painted apartment on the third floor; the building was constructed just before the turn of the millennium.
I noticed that the windows, especially in the mornings in the bedroom, office, and kitchen, are fogged up on the inside edges and have visible water droplets. The windows are partly older wooden windows and partly skylights with metal frames.
I then bought two thermometers/hygrometers from TFA and placed them in the bedroom and kitchen. The humidity levels were between 60-70%.
I have read up online and gathered a lot of tips. We ventilate at least twice a day, usually more often, by fully opening windows for 5-10 minutes maximum, with heating off during this time. The temperature in all rooms is between 19 and 20°C (66-68°F). Laundry is not dried inside the apartment; after showering and cooking, we also ventilate thoroughly and turn on the extractor fan, as well as when the washing machine is running.
Although we notice that during ventilation, the humidity drops to around 40-45%, it rises again within minutes to at least 53% and then slowly moves toward 56-60%. In the morning, the bedroom is about 63-68%, and the kitchen 61-67% (humidity even goes higher during cooking despite ventilation).
We have moisture-absorbing granules in the kitchen and bedroom, but unfortunately, they haven’t made any improvement.
I did not experience this problem at all in my previous apartment and am currently unsure what to do. I plan to start documenting this in writing and then address it with the landlord, but I wanted to ask here first if anyone has any further tips on what I might try.
Thank you very much.
Best regards,

Hi,
thank you for the many replies.
We have been living here since December. The windows face north and northwest.
As an example:
Just now, the bedroom temperature was 19.1°C (66.4°F) with humidity at 59.2%. I ventilated the room, and the humidity dropped to 42.3% at 18.1°C (64.6°F), but within 5 minutes it rose back to 57% and then continued to increase more slowly.
Otherwise, I would say that the temperature in all rooms, except the bedroom, is about the same, so there is no difference between the kitchen, living room, and office.
In my opinion, it cannot be normal for the humidity to rise so quickly again. I believe our heating and ventilation habits are basically fine and follow common recommendations.
One more thing my partner just pointed out: The apartment was probably nearly empty for about 2 months after painting and was likely heated and ventilated rarely or irregularly (October – December).
Best regards
