Compatible with Oclean Electric Toothbrushes – Designed to fit all Oclean adult models (X Pro, X Pro Elite, Flow, Air 2, Endurance, etc.). Important: This is a compatible replacement product, not an original Oclean brush head. Eco-Friendly Biodegradable Material – Made from plant-based, biodegradable materials that significantly reduce plastic waste. The handle is crafted from sustainable, compostable resources – gentle on your gums and kind to the planet. Colour-Fading Replacement Indicator – Blue bristles gradually fade to white over time, clearly signalling when it‘s time to change your brush head (dentists recommend every 2–3 months). No more guessing – just replace when the blue turns white. Premium DuPont Bristles for Superior Cleaning – Featuring high-quality DuPont diamond-shaped bristles with end-rounded tips that effectively remove plaque and surface stains without irritating gums or damaging enamel. W-Shaped Design – The contoured W-shaped bristle pattern follows the natural curve of your teeth, reaching deep into hard-to-clean interdental spaces for a thorough, dentist-like clean at home.
