C. AIR FILTER
The A40 air purifier is equipped with a 4 layer filter package to clean the circulated ro o m
air.
• H E PA (High Efficiency Particulate Airfilter) filter captures allergens like bacteria, dust
and pollen.
• Enzyme filter neutralizes airborne micro organisms.
• Active carbon filter removes unpleasant odours from the air.
• Screen filter captures large dust particles.
The HEPA/Enzyme filter and activate carbon filter continue to work for a long period of
time after opening. The frequency of use and operating conditions determine how often
the filters must be replaced. When the filter is new, the vertical filter lifetime bar lights up
g reen. Depending on the conditions, the lights will be de-activated stepwise. When the
filter is saturated, the ‘Filter’ light
switches on (re d ) . When this happens, take the
