When the red indicator on the panel starts to flash, you must replace the filter.
Replacing a filter:

• Step 2: Please turn the left bottom cover and remove the old filter.
• Step 3: Replace the filter and screw the bottom cover tightly.
• Step 4: After replacing the filter, press and hold the filter reset button for 3 seconds. The buzzer will sound once, and the indicator light will turn white.
• Step 5: After the reset is complete, the indicator goes out.
Caution: Before replacing the filter, please do not forget to cut off the power. Otherwise, the product may suddenly turn on and cause electric shock or injury.
