37mm Phone Filter Mount, M-Series

37mm Phone Filter Mount, M-Series — A Cheap Way to Extend an Existing Video Kit

The gist: The M-Series filter mount lets remote professionals who already own older Moment gear add cinema-style filters to phone video without replacing an entire case system.

• Universal filter compatibility: No Film School reports "any 37mm filter will work with the mount," meaning it works with third-party ND and polarizer filters, not just Moment's own line.
• Solid build for regular use: Constructed from aerospace-grade composites and metals, able to handle being clipped on and off before recurring video calls or recordings.
• Improves on-camera polish cheaply: A polarizer cuts glare off glass and monitors during recorded presentations, an easy quality bump for personal-brand video content.
• Low-cost extension of existing gear: At roughly $5, it's a minor spend for anyone already invested in the older M-Series Moment ecosystem.

No Film School's writeup on Moment's filter mount system describes it as removing "workarounds like gaffer tape" mobile creators used to rig filters before this mount existed.

Best for: remote professionals with existing M-Series Moment gear who want filter access on a budget. Skip it if: you're starting from scratch — a current T-Series case and mount is the actively supported system. Runs ~$5 — check the current price before buying.
