Philips recommends replacing your OneBlade blade approximately every 4 months to maintain optimal shaving and trimming performance. However, the exact lifespan of a blade depends on how often you use it and how long each grooming session lasts.

Signs that it's time to replace your blade:

• The triangular blade wear indicator on the blade has become clearly visible.*
• The blade change light on your OneBlade has turned from green to orange (certain models only).
• You may also notice reduced shaving or trimming performance as the blade becomes less sharp over time.

If your OneBlade has a blade change light, press and hold the power button for approximately 3 seconds after replacing the blade. The orange light turns green to indicate that the indicator has been reset.

*The blade wear indicator becomes visible over time as the crosshatched pattern on the blade disappears. Depending on your usage, the symbol may become faintly visible after just a few shaves, but you only need to consider replacing your blade once the crosshatching has notably faded and the indicator is clearly visible. Refer to the image below to get an idea of what this process looks like.
