Understanding F7 and G4

F7 is a former fine-filter class and G4 a coarse-filter class. Use the ISO classification declared for each replacement. Read the differences between F7 and G4 filters. Before changing class, check that the unit supports the configuration and resistance to airflow.

Do both LG 150 filters have the same function?

The set contains a fine and a coarse element. Follow the unit's arrangement to assign their positions rather than judging by appearance alone.

How often should Pichler filters be replaced?

ZenAero's guide uses 4–6 months as an orientation for many residential installations, not a universal interval for this set. Follow the manual and assess each element and the air conditions; a damaged or heavily loaded filter may need earlier replacement. See replacement intervals and how to change ventilation filters.

These are ZenAero compatible replacements, not original Pichler filters. Check the supported models, pack contents and availability on each product page. For another brand, browse the ventilation filter catalogue.
