Which central ventilation system?

Do you have any with moisture recovery or do you have problems with air that is too dry?

Quick question for people with controlled residential ventilation, where are your supply or exhaust air ducts located? We have them in the basement, ground floor in the ceiling, and in the attic due to the wooden ceiling in the wall. Is it the same for you?

Supply air: living/dining room (one room, two ducts), bedroom, parent’s bedroom, office (each in the floor).
Exhaust air: upper floor hallway wall, upper floor bathroom wall, guest bathroom ceiling, utility room ceiling, kitchen ceiling
No basement

No moisture recovery.

Dry air occurs at around 30% relative humidity. Partial use of a humidifier.

Ground floor/upper floor + attic each in the ceilings.

Without moisture recovery. Problems are very subjective. WE cope well with the dry air. Others may have problems with their mucous membranes or eyes. Therefore, it does not help you if 95 out of 100 answers say "all good," maybe you happen to be among the 5 who have problems.

Whether it benefits me is another matter. However, that does not mean that the opinions on this are uninteresting. Too dry air is also not good for the wood in the house.
