Filteset F7+G4 for the NATHER OPTIMEA ventilation unit, which can remove up to 70% of fine dust. By installing this F7 filter you can achieve high supply air quality for the interior spaces of your home. Thanks to the MiniPleat filter media with fine pleats, a large filter surface and low pressure drop are achieved. Compared with pleated filters (Z-Line), this can reduce the power consumption of the heat recovery unit.

What are the advantages of this F7 fine filter?
• Standard filter class for the supply air side of the ventilation system.
• Reliably removes fine dust, bacteria, and pollen.
• Good value for money.
• Longer service life and less wear on the unit compared with pleated filters (Z-Line).

Key features of the Safeluft filter:
• Solid frame, moisture-resistant and mold-resistant.
• MiniPleat filter media made in Germany with fine pleats.
• Much larger filter surface area compared to folded filters (Z-Line).
• Low pressure drop and longer service life.

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 supply air quality).
