CPL Filter for 70mai Dash Cams
A cheap upgrade with a real impact. This model-specific CPL cuts the dashboard reflection off your windshield, so footage stays clear on bright days instead of washing out — and it is cut to fit 70mai cameras exactly.
Our review
On sunny days your dashboard reflects up into the windshield, and that glare lands right in your footage. A circular polarizing filter blocks that polarized light for noticeably clearer daytime video, cutting reflections from sunlight, wet roads, and other vehicles.
What makes this one worth picking over a generic filter is fit: it is engineered specifically for 70mai models (A810, M500, X800, A510, A500S, A800, A800S), with a silicone-grip inner ring that locks onto the lens without scratching it and an aluminum-alloy frame that shrugs off cabin heat. The multi-coated optical glass keeps 4K footage sharp, and once fitted it needs a one-time rotation to dial in the angle that kills the most glare.
