How long it lasts
Usually every 12 months (12 months at 12 hours a day (Dyson); the machine's screen or the MyDyson app tells you when). The filter light is a reminder, not a water-quality sensor.
After replacing: After fitting, hold the standby button on the remote or machine for about 6 seconds until the display resets the filter life, or reset it in the MyDyson app.
Flow slows and taste drops off as the filter fills up. Changing on time is the whole point.
