Feature: 1. Personalized Fragrance: The air fragrance system provides a personalized fragrance inside that suits your personal preferences and mood. It also helps to ensure improved air quality and greater happiness due to fresh ionization and filtration of external and internal air. 2. Controllable Scent Intensity: The intensity of the scent can be controlled according to your wishes. The fragrance is discreet, it radiates gently and dissipates quickly after closing. The perfume molecules of the perfume in the car will not deposit on the interior surface or your clothes. 3. Oxygen Ioniser: Car air freshener system also ionises the air in the interior. It does this by enriching the air with negative oxygen ions. You breathe fresher air. 4. Super Filtration: The filtration system with activated carbon filter removes fine particles in the external and internal air: thereby adsorbing sulfur dioxide, nitrogen oxides and aromatics. The same applies to odor substances produced in agriculture. 5. Applicable Model: Air fragrance system does not include perfume for FREESIDE MOOD. You can buy other perfumes and an additional perfume box, which you can fill by yourself. Replacement for C E S GLC W205 W213 W222 2015+. Please see the detail description to know.
