This premium supply air filter for the ventilation system Stiebel-Eltron LWZ 70 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, thus ensuring high-quality supply air. Thanks to the filter medium MiniPleat 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 Stiebel-Eltron LWZ 70 device when used in it.

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

The main features of the Safeluft filter:
• Solid frame, moisture-resistant and mold-resistant.
• Filter medium MiniPleat with fine folding made in Germany.
• Filter area several times larger compared to pleated filters (Z-Line).
• Low pressure drop and longer lifespan.

This filter is intended for single use and cannot be rinsed with water or chemically cleaned. A replacement interval of 2-3 times per year is recommended (depending on the quality of the supply air).
