ᐅ Quiet decentralized ventilation system for new single-family home construction

Hello everyone,
During our first consultation with a building professional for a quote, we were asked to choose a ventilation system ourselves, as we are still somewhat skeptical about the "SEVi 160" model proposed by them. Our planner recommended a Halmburger ventilation system – we definitely want to see and listen to it in person. He also mentioned BluMartin, which personally seems a bit bulky to me – and once additional rooms are connected, it starts to feel more like a “central” system again. I also find the cassette filters quite expensive at 50 € (about $55) per unit per year.
We found the videos on the Bayernlüfter website quite appealing, but we are somewhat skeptical about the maximum airflow of 20 m³ (about 710 cubic feet) per hour. We also couldn’t find any information about noise levels at different ventilation rates (which is also missing for the SEVi – but the building professional mentioned that it can be heard).
We are looking for a ventilation system that can achieve an air exchange rate of 40 m³ (about 1,400 cubic feet) per hour (approximately 1 air change per hour for our bedroom) without being audible. Does such a system exist, or does anyone have experience with the mentioned brands? Is an air exchange rate of 1 per hour even necessary for a bedroom with two occupants?
Thank you and best regards.
P.S.: I have the impression that the decentralized ventilation industry is very fragmented with many small players.

That may be true, but in my own home, I want to reduce everything as much as possible. A tablet doesn’t make any “noise.”
Well, we’ll see what options are available that don’t require electricity. Ventilation through windows should also be possible. Although that feels a bit odd. First, sealing the windows tightly, and then having ventilation again. It’s all kind of strange!

Regarding ventilation through the windows:
By extracting the used or humid air, a draft is created, for example, through the roller shutter box to supply fresh air again. Perhaps a bit simplified, but as far as I know, it doesn’t work without electronics.
In other words, you will have to tolerate some noise.

I recommend you listen to them yourself – a PC fan placed in front of you is noticeably louder. I found it audible at level 2 if you concentrate a bit. Levels 3 and 4 are definitely noticeable.I’m currently sitting in the living room watching GI Joe.
At the same time, I’m typing here on my laptop.
I can’t hear the fan at level 2 at all. I do hear the laptop’s fan, which occasionally comes on.
OK – the film’s action scenes and music actually drown out everything anyway.

In other words: you will have to accept some noise.The difference compared to a system with heat recovery is that with window rebate ventilation, cold outside air is drawn in.
Also, to achieve the same ventilation effect as a heat recovery system, the exhaust fans in wet rooms (bathrooms, kitchen, etc.) would have to run continuously. That means cool outside air would be drawn in continuously as well.
If you are bothered by the low noise level of a heat recovery ventilation system, in my opinion there are only two options: a central ventilation system (although I’m not sure how much noise you might hear – there are plenty of people here who can share their experiences on this) or simply airing out by opening windows.
(a small disclaimer – as an amateur, I don’t know the entire ventilation market)
