Packing: filters are packed in a cardboard box for long-term storage in a dry environment.

Advantages of our filter: To the most other analog filters:

• Moisture-resistant synthetic frame. Totally moisture resistant, hygienic, and slim. Operates even at a relative humidity of 100%. Suitable for humid European climate.


• Firmly glued throughout all frame areas. Filter construction is airtight and there are no leakages of dust and other particles through connections.


• Tested according to the new EN ISO 16890 standard.


• Filters are manufactured from high-quality synthetic filtering media. Such filtering material is much stronger and damage-resistant. The holes will not appear on the filter, which may let through the dust and other dangerous particles.


• Extra filtering area. The slim frame does not cover all edges providing up to 5% more filtering area.


• Top high filtering efficiency for smog particles: ePM1 65%


• Lower energy consumption due to a new generation of low-resistance synthetic filter media.
