@CleanAirStars @eswillwalker @JimRosenthal4 I think we're talking past each other. The sensor is used to measure lifetime (since indicator reset) particle load on the filter. If the room air is dirtier over time, the filter gets dirty faster over time.
@CleanAirStars @eswillwalker @JimRosenthal4 我认为我们正在互相交谈。该传感器用于测量过滤器上的颗粒负载的寿命（自指示器复位以来）。如果室内空气随着时间的推移变得更脏，过滤器会随着时间的推移变得更快。
