You'll always know when to replace your toothbrush head All brush heads wear out over time, so check the condition of your brush head regularly and make sure you're cleaning it correctly. Our BrushSync technology tracks how long you use your brush head and how hard you've brushed with it. A BrushSync replacement reminder on the handle and a short beep indicate when it's time to replace the head. Introductory program to ease the transition With our introductory program, during the first 14 uses of your new toothbrush, you have the opportunity to gradually and gently increase the cleaning power of your toothbrush. 14-day battery life The battery life lasts up to 14 days, so you can use it for a long time without charging. Less plastic, more recycling Power adapters may seem small, but collectively their plastic parts have a huge impact on the environment. Just by switching to a USB charger for Philips Sonicare devices in the 1000-4000 series, we can use up to 189,210 kg less plastic per year. Not bad, right?
