Filter replacement for Zehnder ventilation systems made easy – Keep your air and system in top shape

A pleasant indoor climate is an important factor for our quality of life. Modern comfort ventilation systems like those from Zehnder Group play a key role in bringing fresh, filtered air into our living spaces – energy-efficiently and conveniently. But for these systems to continue performing at their best, one thing is particularly crucial: the regular replacement of Zehnder filters.

Why filter replacement is important

The air we breathe is not always as clean as it seems. Fine dust, pollen, spores, soot particles, and other micro-pollutants can affect our health. Especially indoors, where we spend up to 90% of our time, air quality is essential. Zehnder ventilation systems are equipped with high-performance filters that efficiently remove exactly these particles from the air – provided that the Zehnder filters are replaced on time.

A clogged or aged filter can no longer deliver its full filtering capacity. The system must work harder when Zehnder filters are clogged, leading to increased energy consumption, faster wear, and higher noise levels.

Benefits of regularly replacing Zehnder filters

• Healthy indoor air: Fresh, clean air free from fine dust, pollen, odors, and germs promotes well-being. E.g. Fresh Scent (activated coal) filters will be saturated and will lose their capacities to filter odors.
• Protection for the ventilation system: A clean filter prevents dust particles from damaging sensitive system components.
• Energy efficiency: A clean Zehnder filter enables unobstructed airflow, reducing energy consumption.
• Quiet operation: Dirty Zehnder filters increase airflow resistance and thereby the system's noise level.
• Value retention and warranty: Regular use of original parts and timely replacements help prevent consequential damage and preserve the manufacturer warranty.

Regularly check and replace filters

Zehnder Group recommends replacing Zehnder filters every six months. This cycle ensures consistently high air quality and efficient system performance. In addition, Zehnder recommends changing filters that are more finely woven (e.g., Anti Pollen or Hygiene) every 3-4 months.

In addition to user maintenance, Zehnder advises a professional system service by a specialist every two years as well as a cleaning of the air distribution system every eight to ten years.

Conclusion: Small action – big impact

Regularly replacing Zehnder filters is not a minor detail but a prerequisite for healthy indoor air, long-lasting equipment, and high energy efficiency. Those who rely on original Zehnder Group filters and follow the recommended maintenance intervals ensure optimal air quality in their homes – and enjoy peace of mind.

For even greater convenience, Zehnder offers a practical filter subscription, which automatically reminds users of replacement dates and delivers the correct Zehnder filters directly to their home. This way, the indoor climate stays fresh, healthy, and sustainable at all times.
