The Cabin filter contains activated carbon, which can adsorb fine particles, and the activated carbon will gradually decrease with the passage of time and the frequency of use.
If the Cabin filter is dirty, the cooling effect will be reduced and odors will be produced. Inhalation of these odors will inevitably cause harm to the human body.

In normal conditions, two or thirty thousand kilometers will be exchanged once and the period can be cleaned.
