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: Reset the HEPA filter life on the machine's screen or in the MyDyson app.
Flow slows and taste drops off as the filter fills up. Changing on time is the whole point.
