ATTENTION
To protect our environment, please replace the filter after service time is up.
Please pay attention:  if replacing the filter is early then service time is expired but without setting  600‐ the hour memory countdown function, the system will ignore the new filter’s service time, instead of it, the system will continue to count down service time based on the previous filter.
The shell life of the filter is about 4‐6 months.
When replacing the filter, please purchase the replacement filter through a formal channel.
Due to environmental pollution is not the same in each region, we advise every month to check the filter
