Therefore, this blog aims to offer you some points towards several cases to help you know about your air purifier.


I. Filter Installation

  • make sure the appliance is unplugged and no water on hands.
  • Remove all the packaging, otherwise may cause noise.
  • Install filters in right order.


II. Buttons and indicators

1) Filter light keeps blinking: reset the air purifier.

  •   4S: press the button of “filter light” for 3 seconds ( not 3 times).
  •   8L: press the “sleep mode” for 3 seconds ( not 3 times).

III. Better performance

  • Leave enough clearance (20 cm) on all sides of the air purifier.
  • Make sure not to block the air inlet and outlet.


IV. Cleaning suggestions (every 2-4 weeks)

  • Front panel/body of air purifier/air inlet & outlet: clean them by soft, dry towels.
  • Washable Pre-filter: separate it from the Ultra-Duo Filter and wash it by water.

*Note: the HEPA Filter, Antibacterial Filter, Carbon Filter can not be reusable and washed by water.


V. Filter replacement (every 6-8 month)

  • Reset the air purifier to turn off the filter light after having a replacement.

* Note1: the actual replacement frequency depends on its service time and air quality. If it serves for 24/7 or your surrounding air is in the high pollution, it will take shorter to replace. On the contrary, it will take longer.

*Note2: towards the AirMax8L Air Purifier, generally, there is no need to replace the two filters simultaneously. Of the two kinds of filters, the duo carbon filter may not be replaced if it is not so dirty; while the HEPA filter shall be replaced in time because it's the most important one to clean air.


VI. New item with a strange smell (not chemical odors)

  • Foreign objects may be inside.
