• Appropriately selected amount of activated carbon

  FILTRON's active carbon cabin filters trap particles, neutralize odors & gases. Precise carbon amount ensures long-lasting filtration & a clean, fresh cabin.

Cabin filters K 1331A are equipped with a filtration barrier made of fully synthetic non-woven fabric. This material's outstanding ability to capture particles as small as a few microns is achieved through the electrostatic attraction of pollutants by its charged fibers. Unlike natural materials, synthetic fibers are not hygroscopic, meaning they do not deform when exposed to water. This ensures that cabin filters maintain their structural integrity and filtration efficiency even in humid conditions, providing consistent performance and reliable air purification for passengers' comfort and well-being.

Activated carbon filters excel at capturing not only solid particles but also harmful gases. Their porous structure, similar to graphite, facilitates the absorption of harmful gases through a process known as adsorption. Additionally, activated carbon effectively absorbs unpleasant odors that may infiltrate the passenger cabin from external sources. This dual-action filtration mechanism ensures that passengers are shielded from both particulate matter and noxious gases, creating a cleaner and more comfortable environment inside the vehicle.
