Consider the facts:

If you take water and brush to a cabin filter, it will look cleaner, but the tiny particles, such as pollen, fungus or mould spores cannot simply brushed away. The cleaning process may in fact loosen them so that they enter the passenger compartment next time the ventilation system is operated. Other problems also often occur:

  • misting of the windows (icing in winter), because residual moisture from washing the filter can enter the passenger compartment
  • recurring misting of the windows in damp weather, because particles retained in the filter material do not allow the fresh air to pass through freely
  • reduced cooling effect, because residual dirt particles can block the air flow from the air conditioning system into the passenger compartment
  • pollen, dust and dirt particles can no longer be retained, because the electrostatic charge of the filter has been lost due to washing

High-quality cabin filters from MANN-FILTER separate almost 100% of particles less than 0.5 micrometers in diameter as they are electrostatically charged

and contain special multi-layered filter media. They must consist of purely synthetic materials, so that moisture can be absorbed.

Not even a stain remover will help here

Would anyone think that after a quick clean with sponge and brush, an old mattress will give as good a service for the next ten years as a new one? Hardly! It might freshen it up a little, but not make much progress with regard to hygiene and function.

Brief and to the point: You should not experiment with your health. And your active driving safety also makes it worthwhile to replace the cabin filter regularly once a year or every 15,000 km.
