ᐅ How to Properly Dry Out a New Build? Is Using Desiccant Granules Recommended?

Good day.
I am moving into a new condominium. The indoor humidity is naturally still quite high.
Therefore, I want to support the rooms, in addition to proper ventilation, at the beginning.

Does it help to place desiccant dehumidifiers (granules) in each room initially?

Or what would be the best way to quickly dry out the rooms?
For example, like this?
- During the day, keep the windows closed and let the rooms warm up (southeast side),
while running an electric dehumidifier for about 4 hours.
- Then, when I come home in the evening, turn off the dehumidifier and perform thorough airing according to the ventilation schedule
(of course also in the morning before I leave for work).
- I would then also leave the desiccant dehumidifiers in each room as an additional measure.

Would this be an appropriate approach? Or are there other recommendations?

Thank you very much,
erika

With the current weather conditions, moisture is indeed becoming a problem.

Although we have been living in our house for 1.5 years now, the humidity has increased quite a bit in the (more or less) warm season over the past few weeks. In winter, the indoor humidity was around 40-50%. Currently, it is between 70 and over 80% (despite the ventilation system running).
Good ventilation—especially during the cooler morning and evening hours—would usually be a good approach. Unfortunately, the current weather is quite unfavorable, so airing out does not have the desired effect and can even make things worse in the worst case. Hopefully, this unfortunate weather pattern will end soon, as the high humidity is extremely uncomfortable.

At least we have placed a desiccant dehumidifier in the bathroom. I empty the collected water every two days. At first, I was surprised by how much accumulated—now not so much anymore.

I would appreciate any additional tips, as this high humidity is quite frustrating for us.

Hopefully, this unpleasant weather will end soon – the high humidity is very uncomfortable.

At least we have placed a granulate dehumidifier in the bathroom. I empty the water every two days. At first, I was surprised by how much collected – now not so much anymore.

I would also appreciate further tips, as this high humidity is really annoying.

Thank you for sharing your experience.
Why don’t you use an electric dehumidifier?
And what readings do you have, for example, in the bedroom? (Room temperature, humidity) on a rainy day like this?
In my old apartment, I currently have 60% humidity at 22°C (72°F).
Would that level be considered acceptable?

Well – so far, electric dehumidifiers haven’t been necessary.
A month ago, the humidity in the bedroom was between 45 and 55%.
Currently, it is between 67 and 74%. The temperature should also be around 22°C (72°F) – lower at night, since the window is usually open (as long as it’s not raining – OK, I see the mistake: windows are mostly closed and the ventilation is running continuously when it rains).

I wouldn’t worry about 60% humidity all the time – especially since, in my view, this is currently due to weather conditions (which is why I don’t take our high values too seriously yet).
Feel free to correct me, but I think this level of humidity is normal when moving into a new build.

Proper ventilation—especially in the cooler morning and evening hours—is a good way to address this. Unfortunately, the current weather is really unpleasant, so airing out doesn’t have the desired effect (in the worst case, it might even make things worse). Hopefully, this bad weather ends soon—the high humidity is extremely uncomfortable.

At least in the bathroom, we have a desiccant dehumidifier with granules. I empty the collected water every two days. At first, I was surprised by how much it collected—but not anymore.

PS: The room data is not from the new house but still from my old apartment!!!

Correct me if I’m wrong, but I think this level of humidity is normal when moving into a new build.
