This TILLMANER CPL polarizing filter is specifically designed for the 70MAI M310 PRO 2K dash camera, featuring precision engineering that matches the original camera specifications.

This professional-grade filter also serves as protective lens coverage, safeguarding your camera's optics from dust, scratches, and environmental damage. The package includes a polarized tester card to help you verify the filter's effectiveness. Easy to install with a secure threaded mount, this filter is essential for drivers seeking superior video quality and lens protection in varying lighting conditions.
