Older vehicles with a carburetor usually use a cylindrical air filter, with a height of a few centimeters and a diameter between 20 and 60 centimeters. For installation, the filter is placed over the carburetor or throttle valve body, usually located in a metal or plastic housing, which may have a conduit to provide cold or hot incoming air, secured with a plastic cover.

Cellulose filter media impregnated with polymerized resins allow it to be manufactured at maximum speed conditions, ensuring a high pleating memory with fold separator systems and adhesive terminals dosed with adhesives.
