The Nanofilter F9, which can capture up to 85% of fine dust, is the latest innovation in air filtration. This filter combines advanced nanotechnology with superior filtration capabilities to ensure maximum cleanliness and quality of your indoor air. Thanks to the multilayer construction of the filter medium and the use of nanofibers, this filter has a low pressure drop and the ability to capture large amounts of dust before clogging. Additionally, it offers more reliable filter quality than standard synthetic filters, whose filtration performance decreases over time due to gradual electrostatic discharge. In terms of filtration efficiency and durability, it is therefore a better option than the standard F9 filter in our range. The entire filter frame is equipped with a foam seal to ensure maximum airtightness of the filter in the ventilation unit.

Advantages of a nanofilter compared to a synthetic standard filter:
• Advanced filtration: Thanks to nanotechnology, fine particles are captured more effectively than with conventional synthetic filters.
• Lower pressure drop: Despite high filtration efficiency, nanofiber media can keep airflow resistance low.
• Longer lifespan: Thanks to its advanced design, the nanofilter has a longer lifespan and needs to be replaced less frequently.
• Higher efficiency: Provides consistently high filtration efficiency due to the mechanical filtering principle.

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 only 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 incoming air).
