Mercedes W124 Cabin Filter Case | Mercedes W124 Cabin / Pollen Filter Retrofit Frame

Custom designed cabin / pollen filter retrofit frame for Mercedes W124 models.

It can be produced in two different ways: Laser cut from plexiglass / acrylic sheets 3D printed directly from the included STL file The filter media can be replaced easily by opening the frame and installing a new sheet material. You may use: Range hood / aspirator filter material HEPA sheet filter Activated carbon filter sheet Universal cabin filter media Features: Direct-fit style retrofit design Reusable frame, replaceable filter media STL file included for 3D printing Suitable for DIY enthusiasts Improves cabin air cleanliness Recommended Materials: PETG / ABS for heat resistance if 3D printing.
