Effective ventilation with Zehnder filters – for healthy air in your home

A complete set of filters for Zehnder ComfoD and ComfoAir recuperators is key to maintaining clean and fresh air in your home. This set, containing G4 and F7 class filters, provides comprehensive protection against pollutants, dust and allergens. Regular filter replacement is essential for the proper operation of the mechanical ventilation system with heat recovery (MVHR) and affects the comfort and health of household members.

Two-layer protection – G4 and F7

The filter set consists of two types:

• G4 filter: responsible for preliminary filtration, capturing larger particles such as dust, hair, plant pollen and insects. It also protects the more delicate F7 filter from clogging quickly.
• F7 filter: is an advanced filter that captures fine particulate matter PM2.5 and PM10, allergens and bacteria. It provides higher air quality, especially important for allergy sufferers and people with respiratory problems.

These filters meet ISO 16890 standards, guaranteeing high filtration efficiency. The G4 filter is characterized by at least 60% efficiency in removing coarse particles, and the F7 filter – at least 50% efficiency in removing fine PM1 particles.

Wide compatibility and easy replacement

This filter set is designed for Zehnder recuperators from the ComfoD and ComfoAir series:

Long-term investment in health and comfort
