So I have already read and heard quite a bit about [Hoval]. Two friends have installed one or will be installing one. For me, it will also come down to a [Hoval], even if it will probably be more expensive.

Hi!

As we have already written here, you only have the problem of relatively low relative humidity on very few days per year. I personally still find 30-33% bearable.

Please consider with your decision: The ventilation system exchanges the air in the entire house roughly every 2 - 2.5 hours repeatedly. The air is fresh, filtered (reduces pollen allergies!), the living climate is pleasant, and mold formation is prevented.
You can hardly achieve this very pleasant result with window ventilation, at least not without time effort and loss of heating energy compared to controlled residential ventilation with heat recovery.

You do not bring germs into the house with controlled residential ventilation, at least no more than when you ventilate through windows.

Whether to set up a humidifier is up to everyone. Of course, the device must be meticulously maintained so that it does not become a breeding ground for germs.
The alternative is to occasionally open a window or dry a few pieces of laundry in the apartment.

Best regards
Thorsten

I can only agree with that, except for


For me that would be too little, my mucous membranes apparently need a few percent more. It is probably very different what one finds comfortable.

I agree - that would also be too little for me and generally too little for the building fabric (although currently this is only a short period).

Do you possibly have a source for this? I would be interested in the topic. I was aware that too low humidity is not beneficial for health, but bad for the building fabric?

Wood should simply not dry out and you will also find more cracks in the plaster during prolonged dry periods.

So my current level of knowledge...
