Frequently Asked Questions

Q: Will the 37mm CPL filter fit my smartphone?

A: Yes — the clip-on design is universal and works with virtually all smartphones. The large metal threaded hole clamp adjusts to accommodate different phone thicknesses and case styles, ensuring a secure, stable fit without scratching your device.

Q: How does a CPL (Circular Polarizer) filter improve mobile phone photos?

A: A circular polarizer filter works by selectively blocking reflected light waves. When you rotate the 37mm CPL filter, it reduces glare from reflective surfaces like water, glass, or wet roads, and simultaneously boosts color saturation — making skies appear deeper blue and vegetation more vivid, all without any post-processing edits.

Q: Is this CPL filter compatible with action cameras?

A: The 37mm CPL filter is compatible with AKASO action cameras and any other camera system that accepts a standard 37mm threaded lens filter. Its metal threaded hole clamp provides additional mounting versatility beyond the standard clip-on attachment.

Q: How do I care for and store the CPL filter?

A: Use the included microfiber wiping cloth to gently clean the lens surface. When not in use, place the filter back in its protective cover and store it in the provided storage bag to prevent scratches and dust accumulation, extending the life of your CPL filter.
