Hmm, my apartment has a 4-6 inch hole for air exchange in the living room, but is otherwise a tight air envelope due to being a relatively modern building. Is there...something I can buy for this? This seems reasonably doable, unless I'm missing something obvious.

- Too 3y agoYou surely have air egress in your bathroom and kitchen fan? Modern apartments usually have these on low speed all the time, creating a flow from the rest of the intakes in other rooms.
- amluto 3y agoThis is a nice balanced system. I don’t know whether it can run in a positive pressure mode: https://products.zehnder-systems.com/en/product/zehnder-comfoair-70 https://products.zehnder-systems.com/en/product/zehnder-comf... Its big sibling, the Q series, can run balanced or at a configurable amount of imbalance. These are really neat, but they’re intended for a pair of holes in different rooms. Maybe you can get one and get it to run in supply only mode: https://www.lunos.de/heat-recovery https://www.lunos.de/heat-recovery
