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.

SO, now more than a year has passed with the decentralized fans.
First tip: Definitely buy the recently available Silent series. They are really very quiet.
Further feedback will follow soon!

Which quiet (!) heat exchanger would fit into the existing 18cm (7 inches) opening? I would at least like to replace the one in the bedroom. Ideally, it should be virtually inaudible.
