Zehnder Filters (premium analog filters)

Zehnder filters – designed for Zehnder ventilation units

High-quality Zehnder filters are the optimal solution for maintaining clean and healthy indoor air in your Zehnder ventilation system. Properly selected Zehnder filters reduce the amount of dust, pollen, smog particles and other airborne pollutants entering your home. This not only improves breathing comfort but also protects the heat exchanger and fans from contamination. By using reliable Zehnder filters, you help maintain stable airflow and consistent system performance throughout the year.

Our range includes compatible replacement solutions for popular models such as Zehnder ComfoAir and Zehnder ComfoAir Q. These Zehnder filters are manufactured to match original specifications and ensure secure installation and dependable filtration. When replaced on time, Zehnder filters support better energy efficiency and contribute to a quieter, smoother operation of the ventilation unit.

All offered Zehnder filters comply with ISO 16890 standards. Filtration performance has been tested and confirmed by the FIATEC laboratory in Germany. We use EU-manufactured filter media, including advanced 3-layer technology with increased dust holding capacity. This allows Zehnder filters to maintain high filtration efficiency and stable airflow for a longer service period, even in environments with higher pollution levels.

Choose the right filtration class according to season, location and individual sensitivity to allergens. Our Zehnder filters are suitable for residential and light commercial applications. In urban areas or near busy roads, higher filtration classes are recommended to reduce exposure to fine particles. Families with children, allergy sufferers or pets especially benefit from high-quality Zehnder filters that help create a cleaner indoor environment.

Available filter classes:

• G4 – basic protection against coarse dust particles.
• F7 – effective filtration of PM2.5 and PM1 particles.
• F7/AC – activated carbon layer for odor and NOx reduction.

Regular replacement of Zehnder filters ensures optimal air quality and long-term performance of your ventilation system. All filters are produced in the European Union and include a 2-year storage guarantee.
