Simply changing the filter does not automatically clear the warning. [1, 2]
To turn off the red light:
Turn the air purifier on.
Press and hold the main Fan Speed button (the button with the fan icon). Continue holding the button for 10 to 15 seconds (it may take up to 30 seconds for some variants) until all LEDs flash and the red light disappears.
Release the button. [1, 2, 3, 4, 5, 6]
