Does G4 media replace the complete F7 filter?

These items have different construction, dimensions and classes. Check the media holder and the F7 filter position before combining them in an order.

F7 filters and G4 media are different products

Compare construction, holder and position as well as dimensions. G4 media is not automatically a substitute for a complete F7 filter. Read the differences between F7 and G4 filters. Before changing class, check that the unit supports the configuration and resistance to airflow.

When to replace media and complete filters

G4 media and an F7 filter may require different replacement schedules. Follow the manual and do not wash an element unless its instructions allow it. Our guide to ventilation filter replacement intervals distinguishes filter types and operating conditions.

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