This premium supply air filter for the ventilation system Zehnder ComfoWell 520 is suitable for users who have the highest demands on the indoor air quality of their home. With its well-thought-out design, high-quality workmanship, and excellent filtration properties, it even surpasses the filters provided by the device manufacturer. After installing this filter, up to 85% of fine dust can be separated, ensuring high-quality supply air. Thanks to the MiniPleat filter medium with fine pleating, a large filter surface area and low pressure loss are achieved. Therefore, this filter has no significant impact on the performance or power consumption of the Zehnder ComfoWell 520 device when used in it.

• The highest available filter class for heat recovery units in private households.
• Filters even fine dust, bacteria, pollen, soot, and tobacco smoke.
• Suitable for users who require high supply air quality (allergy sufferers, asthmatics, families with children...).
• Thanks to the MiniPleat filter medium with a large filter area, it has only a minimal impact on the performance or energy consumption of the device.
