Mi sono trasferita in un nuovo appartamento 6 mesi fa, tutto andava bene finché non ha iniziato a fare freddo, ora ho delle macchie di muffa in tutto l’appartamento. Ventilo il mio appartamento due volte al giorno, non posso fare di più perché lavoro da casa e fuori fa davvero freddo e il mio riscaldamento è sempre acceso 2. Come posso gestire questa cosa? pulire lo stampo di tanto in tanto dovrebbe essere sufficiente o ho bisogno di qualcosa di speciale? devo dirlo al padrone di casa?

Lüftung! Open all windows, 5-10min. Air should completely replace. And after maintain 18degrees.
You have to open your windows more often
Employ something called “stoßlüften”, basically fully open your windows for 5 minutes, then close them again. Your stuff in the apartment and the walls/floors/ceilings will stay warm, just the air needs to reheat. Do that 3-4 times during your workhours and you are gonna be totally fine.
The only solution here without doing something structural to your home: vent more. See if you can leave a window on a tiny crack or something. If this forms within a couple of hours then this is A LOT of condensation. Do you shower a lot? Or constantly making tea?
Black mold is best cleaned with some chlorine solution. Please be aware black mold is very bad for your health. Read up on how to avoid and clean it.
You should contact your landlord about it, you are obliged to do so under the Mietrecht. It might also be the case the landlord is responsible to solve this issue if it is a purely structural thing (or bad ventilation possibilities). However, if you don’t vent enough and don’t heat the apartment sufficiently than it might be on you. I cannot judge that from here.
Keep in mind that houses in Germany are built for the winter and not for easy reconstruction after natural catastrophies. Germans do not have ventilation systems built into the walls or ceilings so it is up to you to ventilate. I saw that in USA people tend to keep the windows closed and regulate humidity and temperature with a central device. Germans prefer heat radiators and open windows for control of heat and humidity.
Your landlord would say you’re breathing way too much.
I suggest you get yourself some hygrometers too, easier to monitor the humidity that way.
The heater [set to 2](https://en.wikipedia.org/wiki/Thermostatic_radiator_valve#Temperature_scales) means 16 degrees (or 17 on Danfoss), that seems a bit too cold. Crank it up a bit and ventilate more.
Get a thermometer with hygrometer and monitor the humidity.
If the windows are single-pane, you’re basically out of luck, but if they are not, you should be able to keep them dry.
People think it’s the cold that would make them sick but in reality it’s lack of ventilation.
Open your windows more often and consider getting a dehumidifier
Clean your mold often, its not healthy for your respiratory system. Clean it with vinegar. Wipe of the water from the windows. Dehumidifier.
It’s not just ventilation. The temperature inside could also be too cold.
Additionally to ventilate your room more frequently you may get an electric dehumidifier. But don’t get one for 20 euros on Amazon. One that actually works (has enough power) will probably cost about 200 euros.
In addition to what people has said about proper ventilation and increasing the heaters temp (3 would be better), cross ventilation helps a lot. That means completely opening all windows for a few minutes so that a stream of air can flow through the apartment. Of course that means leaving room doors open. Doing that twice a day should be enough. Also male sure that if you have furniture or closets next to any of the walls facing the outside you have to leave certain gap between the furniture and the wall, at least 20 cm or so. If you have the option to place the furniture somewhere else other than these walls then that’s a better alternative.
If you still see the condensation after doing all this then there’s a problem with the apartment itself and that needs to be fixed by the landlord.
The problem with mold doesn’t appear suddenly, so you might already be having this problem for a few weeks.
I usually open my windows 2 times a day for 10 minutes. Prevents any moisture buildup for me.
I had a similar problem in my home in Finland after I did some renovations, note I am not German.
1. Build a silica gel channel at the bottom of the window, it captures moisture and prevents it from collecting; it’s not infinite nor foolproof, but mold will not grow near silica gel beads.
2. Dehumidifier, not only it heats up the room, but also keeps moisture level low.
3. Open doors to other places, actually the moisture you see in the windows come from your lungs; that’s you breathing that out, if you don’t want to ventilate to the outside you can ventilate towards other rooms that have lower moisture. You say you live in an apartment, if you were to place a fan towards the outside hall somehow, say by making the gap of your door larger and provided the outer building is similar temperature as your inside, you can literally vent your humidity to, the staircase.
4. ERV but that’s more advanced.
It however seems that dehumidifier is your better option given you live in an apartment.
They work, trust me; whenever you are in, keep it on, all the energy that the device produces becomes heat, so it’s like running a heater, I’ve measured it, warms the room 1C or 2C compared when off.
Open you windows and maybe turn down your heater if it’s all the way turned up
So I‘ve been in Germany since 2017 and I never had to ventilate as much as here. Changed more than one apartment since living here, different buildings, different windows… is it poor construction? I‘m genuinely curious. I own two houses in another country (same weather conditions as here, basically) and NEVER did I have to deal with mould or WET corners of the room. Never did I have to think about ventilating the apartment 5 times a day or else the big bad mould will get me. It’s kinda annoying.
lol you summoned the stossluften demons
