greater need for healthy air. For this reason, the appliance allows you to  
adjust the sensitivity of the air quality sensor. If you set it to higher sensitivity  
level, the appliance starts cleaning the air at lower pollution level.  
There are 3 sensitivity levels:  
-
-
-
standard  
sensitive

Filter replacement  
Filter maintenance  
This appliance is equipped with the Healthy air protect lock to ensure that  
the filters are in optimal condition when the appliance is operating.  
When one of the filters is almost full and has to be cleaned or replaced,  
the appropriate filter replacement light starts to flash.When you do  
not replace the New home filter, the appliance stops operating and the  
appliance is locked.  
When the appliance is locked, the filter replacement light of the filter  
concerned lights up on continuously.  
Note: Only replace a filter when the filter replacement light flashes. If you  
replace the filter before the filter replacement light starts flashing, the lifetime  
counter will not be reset but will continue counting the lifetime of the previous  
filter.As a result, the filter replacement light will start flashing much too soon.  
Filter replacement lights  
The filter replacement lights indicate which filter has to be cleaned or  
replaced.  
-
Filter replacement light 1 flashes: filter 1 (the pre-filter) has to be  
cleaned. See chapter ‘Cleaning’ for further instructions.
