Controlled residential ventilation - filter directly in exhaust valves

We also have filter bags in the exhaust air valves and change the filters approximately every three months.

would be about ~100-150€/year just for the exhaust air filters... that wouldn't be worth it to me now.

One more question at this point, if I replace the existing supply air filters F4 with an F7 pollen filter, will the volume flow of the entire system also change?

that much? I would come to 28 euros if I changed them every time. However, I only change them regularly in the kitchen. Otherwise, I just vacuum them.

An exhaust air filter costs about €1.40. Even less in larger quantities, the costs are reasonable. I don't know how you arrive at €100 - €150 now?

We did that, nothing changed for us.
