Activated carbon filters K 1331A
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.
