    How often do I need to replace the sensors of my Philips Deep Sleep Headband?

    Published on 2021-08-30
    You can use the sticky sensor behind the ear up to 3 times. Do not use each SmartSleep sensor more than 3 nights because it could affect device performance. The SmartSleep Sensor (behind the ear) is considered a disposable component and should be replaced every 3 nights.
    You can order the sensors from our online shop.
    Note: The gel in the middle of the SmartSleep Sensor is very important to its function. If the gel becomes dislodged, discard the sensor and use a new one.
