It’s not true. If building has any reasonable ventilation (and it must have one in order to pass inspection and norms) it should has at least 3-4 air exchanges per hour. So drying inside wouldn’t make that much of a difference to cause mold by itself. It may be different if ventilation system is not functioning properly but in that case it should be fixed anyway.
- majewsky 6y agoAre you refering to German building codes here? Most German apartments that I know have no active ventilation system except in the bathroom and maybe the kitchen.
- tikej 6y agoAs far as I know, yes (although I don't live in Germany) but with disclaimer that it possibly allows old buildings to stay with the ventilation they were build with (which used to have decent ventilation via fairly poorly airtight doors and windows). It doesn't matter whether it's active (and by active you mean having ventilation hole in the room or fan?) or not – it should provide necessary exchange anyways. Maybe it's not true for the old buildings that weren't updated but in that case they are not healthy to stay in – whether with or without line drying.
