The replacement of the filter is indicated by the built-in program. The filter can also be replaced based on the service life prompt or the filter life reset function.

Filter Life: The filter life is set to 3000 hours. Indicators go off every 600 hours. When less than 150 hours remain, the filter reset key lights up red and the last indicator flashes (1Hz) to prompt replacement.

Resetting Filter Life:

• If remaining filter life is not less than 150 hours, touching the filter life reset key (for more than 3s) will only produce a prompt tone "ding".
• If remaining filter life is less than 150 hours, the filter life reset key flashes. Touching the reset key (for more than 3s) will reset the filter life and produce a prompt tone "ding". The indicators will be fully on when reset is successful.

Forcible Reset of Filter Life: Press and hold the filter reset key (for more than 3s) within 30 seconds of powering on in standby mode. The filter life will be reset, and a prompt tone "ding" will be heard. The screen will flash 6 times, indicating completion. All filter life indicators will be fully on after restarting the machine.
