A: Hello, the Winix 9800 air purifier is a 4-stage filtration. The pre filter and plasmawave will last forever (pre filter can be washed). We do recommend changing the carbon filter once every 3 months (you get 4 in the box for a full year of filtration) and the true HEPA once a year, or when the check filter indicator light comes on. The Winix filter indicator is based on actual usage due to our smart sensors, and not a timer.
