When to replace filter
The filter life depends on the actual working environment. In the normal service
environment, the filter life is 1,500 hours. After about 1,350 hours (90% of rated
lifecycle) of cumulative operation, the Filter Alarm light will flash to remind you to
purchase and replace the used filter. Replace it with a new one, then press and hold
the Filter Replace button for 3 seconds. And the Filter Alarm light goes out as the
buzzer makes a beep.
