Check the filter and camera lens carefully to ensure both are clean and dry. Use the cleaning cloth to clean them if needed. Apply the filter in a clean and dry environment, as any foreign objects on the camera lens or filter surface may affect the final result.

Avoid using the camera in the rain or water sports when the filter is installed to avoid water getting into the filter, as this may affect the final result.

To prevent damage, avoid dropping the filter, exposing it to strong impacts, or letting it come into contact with hard objects. If the filter becomes damaged, replace it immediately.

When not in use, store the filter in the carry case.
