Filters for Zehnder ComfoFond-L Recuperators – Effective Protection for Your Ventilation System

These G4 filters are specifically designed for Zehnder ComfoFond-L 350 and 550 recuperators, ensuring efficient air filtration in your home. These are original filters engineered exclusively for compatibility with these recuperator models. Their purpose is to protect the heat exchanger from contaminants, ensuring efficient and long-lasting operation of your entire ventilation system.

Compatibility and Fit

These filters are compatible with ComfoFond-L 350/550 units manufactured between 2012-2015. It is essential to verify your unit’s model — these filters do not fit newer versions produced from 2015 onward. The filter design enables simple and intuitive installation without requiring additional tools. The tab on the frame facilitates easy removal during replacement.

Filtration Class and Efficiency

G4 filters offer medium filtration efficiency, capturing at least 60% of particles 10 micrometers in size (compliant with ISO 16890). This ensures effective removal of dust, pollen, and other airborne contaminants, significantly improving indoor air quality. They provide relatively low air resistance while maintaining high filtration performance.

Construction and Durability

The filters are constructed from high-quality materials, bonded and sealed within a durable plastic frame. They are moisture-resistant and intended for single-use dry cleaning (vacuuming only). Clear markings on the filter indicate the correct installation direction. Thanks to a specialized design, the filters feature maximum filtration surface area, resulting in extended service life.
