2x Carbon Cabin Filter Filtron K1111A
The Filtron K1111A cabin filter with activated carbon is an advanced solution that effectively protects passengers from air pollutants inside the vehicle. Thanks to the use of innovative technology with the BIOKNIGHT antibacterial system, the filter offers a high level of protection against harmful allergens, bacteria, and smog particles.
How does the Filtron K1111A cabin filter work?
This filter features a multilayer construction, with a crucial layer made of activated carbon. Activated carbon effectively neutralizes unpleasant odors and absorbs harmful gases such as nitrogen oxides (NOx) and ozone. Additionally, the BIOKNIGHT system, based on a special antibacterial coating, provides dual protection:
- Phase one – neutralizing allergens
Electromagnetically charged long-chain carbon molecules attract allergens and destroy their cellular structure. - Phase two – preventing microorganism reproduction
The filter effectively inhibits the growth of bacteria and other microorganisms, preventing their multiplication and eliminating their negative impact on passenger health.

Why should the cabin filter be replaced regularly?
Polluted air can lead to serious health issues, such as:
• Respiratory tract irritation
• Allergies and asthma-related reactions
• Weakened immune system
• Chronic fatigue and headaches
Replacing the cabin filter every 15,000–20,000 km or once a year—especially before allergy season and the heating period—ensures clean and fresh air in the vehicle cabin.
