Hello Forum,
We have been living in our house (newly built, timber frame construction) for 9 years now, and we have had a severe dust problem almost from the beginning. You can see dust particles floating in the air when sunlight shines through, and if I cleaned now, I would see it settled again the next day. I am not talking about large dust flakes but rather the fine dust particles.
We heat the entire house with underfloor heating. Recently, we also installed air conditioning units (split systems) in the rooms, and since then we sometimes use these units for heating as well, but only to a small extent. All the beds are quite new, there are not many pieces of furniture, and instead of curtains, we have blinds. We have also tried ventilating by fully opening the windows for fresh air multiple times, but this did not significantly improve the situation. So it should not be due to any of these factors.
As a layperson, I would assume that the air humidity is too low, if it were not for my other problem: mold growth on the silicone seals of the windows. It is not uncommon for water to form overnight on these silicone seals. We always try to wipe it dry, but apparently without success. Slowly but surely, mold is starting to appear on these seals, especially in the corners. Our windows are double-glazed.
Could it be that the house is simply too well insulated? (Even if that may sound odd).
As I said, I am a complete layperson in this field and would appreciate any advice!
Kind regards,
Fabian

They centralize these. On other days, they run only in individual rooms with closed doors. Set to automatic, so the units start running when the indoor humidity exceeds 65%.
Do you actually have indoor humidity over 65% (excluding the bathroom)? That probably only happens during two weeks of continuous rain outside, right?

Although we are new to building a house, we have acquired two things:
a) A dehumidifier for each floor at around 180 euros (for up to 72m2 (775 sq ft)):
These are mainly placed in central areas. On other days, they are used in individual rooms with the doors closed. They are set to automatic mode, so the devices start operating when humidity levels exceed 65%.
b) A powerful air purifier costing 230 euros, which is said to filter pollen, mold spores, and fine dust from the air. The sensor works quite well: as soon as I need to do some shredding and the air purifier is nearby, it immediately detects the increased pollution and intensifies the performance. We keep moving the air purifier to different locations as needed. We might buy a second device.
P.S.: If anyone finds this setup problematic in any way, feedback or criticism is welcome 65% humidity in living spaces?
We only experienced that in the basement during summer in our new build, so that’s why we placed these two devices there for a while...
We also needed the air purifier at the beginning because there was
so much dust...
But after wiping everything once a week in the early phase and running a cleaning robot, it eventually became unnecessary.

Without airing out or using dehumidifiers, the levels would be higher. Since this is a new build, I hope this is normal.
