ᐅ Do construction dehumidifiers still work effectively if non-woven wallpaper has already been installed?

Hello,

I am considering getting this dehumidifier:

Aktobis WDH-930EEH

Is it effective if there is already non-woven wallpaper installed?

Second question: When the device is running, do all the windows need to be closed?

The device is a toy.
If you still decide to get it, the windows should be closed.

However, I expect similar or even better drying results if you don’t buy the device and instead ventilate properly.

Proper ventilation means: warming the rooms, then airing them out thoroughly by opening windows briefly, and repeating this regularly. Ideally, 5-6 times a day.

It's enough without heating as well. Just open all the windows from noon until evening. During the day, the sun warms the rooms and the air is very dry.

And the dryer is really just a toy. If you need something like that, it's better to rent one.

Sorry, this has to be said. Please don’t take it the wrong way what I’m about to write! Made my day :-p especially since you’re a guy :-) and asking questions like these.

Regarding 1) Why wouldn’t it work? Do you think your thin wallpaper prevents the wall from drying?

Regarding 2) You can also keep the window fully open. If you really want to blow energy = heat outside and pay a lot for construction electricity, that’s your choice.

Geez... *shaking my head*

Thank you for the helpful advice. So it’s better to ventilate several times a day rather than buying a device like that.

And does this also work if the wallpaper is already on the walls?

Yes.

Oh dear, the wallpaper question again :-)

If ventilating isn’t enough, talk to your shell builder or screed installer. They can lend you a professional unit for cash. But these devices use a lot of electricity, so don’t overdo it.
