Why does the filtered water taste weird? 
 1) The filter is about to expire. Check the reminder indicator to confirm and replace
 him out.
             2) The system has not been used for a while. Turn on the RO tap and let it
 Rinse for a while before drinking.
 
 
 What happens if I don't change the filter when the
 Filter life indicator lights red? 
 Excessively stressed filters deteriorate the filter performance, so that pollutants are released back into the water
 and may affect your health. It is recommended to replace the filter when
 the filter life indicator lights red.
 
 
 Why does the filter life indicator still light up after changing the filter
 red? 
 You have not reset the filter life indicator. Please reset it: Press and hold the
 RO filter life indicator for 7 seconds until the system beeps and the 
blue light remains on.
