3 REPLACEMENT HEADS: Brush heads must be changed at least every 3 months to maintain an effective cleaning. This pack of 3 hygienically sealed replacement brush heads are to be used exclusively with TAO Clean Umma Diamond Sonic Toothbrush and Cleaning Station. PATENTED DOCKING STATION: Sanitize your replacement toothbrush head by placing it back in the TAO Clean Base Station after use. Using powerful Ultraviolet-C rays to kill 99.9% of germs, it also protects, dries, and charges your toothbrush. DUAL SPEED SETTINGS: Pick the setting that’s perfect for your mouth. The TAO Clean toothbrush has dual settings (Super Clean & Sensitive Clean) and a 2-minute timer that pauses every 30 seconds to remind you to move to the next section of your mouth. TWO-YEAR WARRANTY: TAO Clean products have a two-year warranty covering manufacturer-related defects. These replacement toothbrush heads are available in Super Nova White and Deep Space Black to match your existing TAO Clean Sonic Toothbrush.
