Zehnder Filters (premium analog filters)

Zehnder Filters – Adapted for Zehnder MVHR Units

High-quality Zehnder filters – an optimal solution for Zehnder MVHR units when you want to ensure clean, healthy and comfortable indoor air. Properly selected Zehnder filters help reduce the entry of dust, pollen, smog particles and other pollutants into indoor spaces, making it easier to breathe both daily and during allergy season.

In addition, these filters protect the heat exchanger and fans from contamination, help maintain more stable airflow and contribute to more efficient operation of the unit.

Wide Compatibility

Our assortment includes replacement filters designed to ensure compatibility with Zehnder units. These filters are suitable for popular models including Zehnder ComfoAir, Zehnder ComfoAir Q and other MVHR units from this manufacturer.

Replacement filters match the quality of original solutions and ensure reliable air filtration while helping maintain more stable system operation. When filters are maintained on time, dust accumulation inside the unit is reduced, and the MVHR unit operates more smoothly and quietly.

Proven Quality and Advanced Filtration Technology

All offered Zehnder filters comply with the ISO 16890 standard. Filtration efficiency is confirmed by the FIATEC laboratory (Germany).

We use filter media only from European Union manufacturers, and the innovative 3-layer filtration media features higher dust holding capacity – meaning longer service life and more stable filtration efficiency throughout the entire usage period. Higher dust capacity helps maintain consistent airflow for longer, ensuring Zehnder filters remain effective even in more polluted environments.

Flexible Choice Based on Needs

Choose the appropriate filtration solution based on season, living environment and individual sensitivity to dust or pollen. In cities, near heavy traffic or industrial areas, higher filtration classes are more often chosen, while in quieter locations basic protection may be sufficient.

It is also worth considering whether there are children, allergy-sensitive individuals or pets at home – in such cases Zehnder filters help maintain more comfortable indoor air quality.

Available Filter Classes

  • G4 – for basic protection against lint and coarse dust particles.
  • F7 – for filtration of PM2.5 and PM1 particles (smog particles, fine dust, allergens).
  • F7/AC – activated carbon filter that absorbs odours, volatile particles and NOx gases.

Why Choose Zehnder Filters from CleanFilter Store?

  • ✅ Thanks to large volumes, you get the best prices.
  • ✅ Quality confirmed by testing results.
  • ✅ Long filter lifetime due to 3-layer filtration media.
  • ✅ Wide selection for Zehnder ComfoAir and Zehnder ComfoAir Q series.

Why Is It Important to Replace Filters?

Regular filter replacement helps maintain optimal air quality and efficient MVHR operation throughout the year. All filters are manufactured in the European Union and have a 2-year storage guarantee.

If you want even better protection for more sensitive individuals, choose F7 or F7/AC class – especially relevant in cities, near heavy traffic and during pollen season.
