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

• Advantages of our filter: To most other analog filters:
  
  
  
  • 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. The 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.
  
  
  • High filtering efficiency for smog particles: ePM1 70% (most analog 55%).
