ᐅ Controlled residential ventilation – filters installed directly in exhaust vents

Hello everyone,
I have a question: do you have filter bags installed directly in your exhaust vents to catch dirt right there? According to DIN standards, this is apparently required for the kitchen.
I once installed filters in all the exhaust vents, and after about 3 months the filters were so dirty that hardly any air was being extracted anymore. Seeing this, I wonder how the exhaust ducts look after several years without filters directly in the vents.
Simply installing them is not an option either, since the values would no longer be correct because the filters cause a pressure loss.
I would like to know if you have installed any filters or not, and what your installer told you about this.

That would be about €100-150/year just for the exhaust air filters... I don’t think it’s worth it for me.That much? I would come to 28 euros if I replaced them every time. However, I only replace them regularly in the kitchen. Otherwise, I just vacuum them.

A different question here: If I replace the existing supply air filters F4 with F7 pollen filters, will the overall airflow of the system change?We did that, and nothing changed for us.
Best regards,
