Are all DF EVO kits interchangeable?

No. EVO 1/2 and EVO 3/4 are distinct sizes. For OPTIMA and BASIC, check their inclusion on the EVO 1/2 product page instead of assuming compatibility with every EVO set.

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 Siber filters. Check the supported models, pack contents and availability on each product page. For another brand, browse the ventilation filter catalogue.
