ᐅ Controlled Residential Ventilation – What Should You Consider When Choosing One?

I’m torn when it comes to the topic of mechanical ventilation with heat recovery. My wife is very skeptical; partly because she worries about drafts (she is quite sensitive to that) and also (and I partly agree with her here) because of concerns that mold or similar could eventually build up inside the extensive ductwork.
1) Does anyone here have long-term experience with mechanical ventilation with heat recovery? At least around 10 years?
2) What are established or reliable brands that you would recommend? Are there any manufacturers you would advise avoiding?
3) What should you pay attention to (manufacturers, building-specific details, etc.) if it is important to avoid feeling any airflow?

Airflow? Where is that supposed to come from?Since air is extracted from the rooms and fresh air is blown in, an airflow inevitably occurs. Ideally, it should not be noticeable...

In a show home, the Proxon system installed there was casually recommended to us with claims like "silent, you don't even notice it," and so on. The 15 minutes we spent inside the house were enough for us. I know this is a different system, but what I want to say is: I hope that the airflows in a normal controlled ventilation system are significantly, significantly lower...

Experience-based insights would be really helpful here. Controlled ventilation has been around for decades (especially in commercial and office buildings). In single-family homes, it has become more common since passive houses appeared (over 10 years ago?).
I have just over one year of experience, and only with one property. Within my family, there are also more than seven years of experience with two rental properties (no issues). In any case, I would definitely choose controlled residential ventilation again (and never without it).

Using natural building materials like wood and clay when constructing, and, if possible, designing spacious rooms, also helps prevent moisture problems. That may be true, but it doesn’t change the fact that CO2 and other gases are kept automatically within safe levels long-term by controlled residential ventilation.

Proxon system being promoted, It’s not a ventilation system, but rather an air heating system; these are two different things.
It’s roughly like comparing a pickup truck with a dump truck.

Yes, of course. What I meant to say: Hopefully, the airflow of the Proxon is significantly higher than that of common mechanical ventilation systems for controlled residential ventilation!?We have a ventilation outlet directly above the sofa – when I stand right underneath the sofa, I notice a slight draft – but when sitting, you don’t feel anything at all. The system itself is installed in the attic and runs at level 3 out of 4, which is inaudible during everyday use (the refrigerator is louder).I was at a neighboring house last weekend that didn’t have a ventilation system. In short: I’m glad to have one.
