Currently I am in a very stupid position of our housing association having removed the cladding and insulation from our building (just at the start of winter) leaving exposed blockwork on our external walls, one of which is also our bedroom wall. We have wall-mounted air-conditioning unit things which are pretty shoddy and poorly mounted and, as a result, the wall gets freezing gold overnight and is getting condensation build-up turning into black mould. We removed the air conditioning unit (it’s literally just covering a hole in the wall, no grill or anything) and have just duck taped over it until a solution can be found.
Yes, been there. Couldn’t understand why anything that touched the carpet was going mouldy until I realised the fucking thing was damp because of the supposedly ‘so fine it won’t get anything wet’ humidifier.
I am now obsessed with dehumidifying and have hygrometers that I check excitedly.
I hired a massive dehumidifier recently to dry out parts of our house after the roof leaked and the ceiling came down (it was as big as me and I had to get my boyfriend to lift it, and I normally lift very heavy weights. Man it was BIG.)
Currently got a small one on hire but I’m paying a tenner a week and we’ve had it 7 weeks now which is silly as I could’ve bought one for that amount of money.
In terms of my advice to you, I would run the humidifier for half an hour before bedtime and turn it off before getting into bed, so that the air is moist for your sleep. (if it has a timer you can maybe set it to switch off an hour after gong to bed.) You shouldn’t let it run all night, esp if it’s causing you damp.
