Check Authoritative Certifications and Test Reports
Request third-party test reports: Ask the seller for a complete environmental safety test report for the materials; verify the report's authenticity to avoid products with forged documentation.
Confirm compliance certifications: Specifically check for EU RoHS 2.0 certification and adherence to relevant home appliance safety standards to avoid risks associated with excessive levels of harmful heavy metals or plasticizers.
Direct Inspection (In-Person or Upon Unboxing)
Check for odors: Smell the device casing immediately after unboxing. Safe, high-quality materials have no pungent or unpleasant odors; a strong smell of plastic or acrid chemicals suggests the use of inferior recycled waste materials, and such products should be avoided.
Inspect appearance and texture: Safe, compliant materials have a smooth surface free of burrs, impurities, or black specks. Casings made from inferior recycled materials often exhibit rough workmanship and dull, uneven coloring.
Targeted Verification Based on Usage Scenario
For use with infants: Specifically confirm that parts coming into contact with the baby are made from skin-friendly, safe materials-such as food-grade silicone-to prevent harmful substances from coming into close contact with the infant.
For use in enclosed bedrooms: Prioritize materials that are odorless and environmentally certified to prevent the slow release of harmful substances in a confined space, which could negatively impact sleep health.
