Filters for Zehnder ComfoFond-L recuperators

These G4 class filters are dedicated to Zehnder ComfoFond-L 350 and 550 recuperators, providing effective air filtration in a mechanical ventilation system with heat recovery. Their task is to trap dust, pollen and other contaminants, which translates to cleaner air in the rooms and a longer lifespan of the device itself.

Application and efficiency

G4 filters are a basic element of recuperator maintenance. Regular filter replacement (recommended every 3-6 months, depending on the degree of air pollution) ensures optimal device performance and high quality of filtered air. These are pre-filters that protect more accurate filters (e.g., F7) from clogging quickly, extending their life and reducing operating costs.

• They trap dust, plant pollen, seeds and other larger contaminants.
• Protects recuperator components from damage caused by contaminants.
• Helps maintain optimal airflow in the ventilation system.
• Helps improve air quality in rooms, reducing allergens and irritants.

Warranty and reliability

The manufacturer provides a two-year warranty on these filters, which confirms their high quality and reliability. Thanks to this, you can be sure that you are investing in a product that will last a long time and fulfill its task. The filter is easy to replace - the process does not require specialized tools or knowledge. Simply open the filter housing in the recuperator and replace the used filter with a new one.
