ABSTRACT:
In an air purifier apparatus, an electrostatic filter is detachably and operatively connectable to an electrical contact which in turn is connected to a terminal of a power supply. The electrostatic filter is also detachably and operatively connectable to a second electrical contact which is connected to an alarm device. When the electrostatic filter is properly mounted within the air purifier apparatus, the two electrical contacts are short-circuited, thus electrically connecting the power supply to the alarm device through the electrostatic filter. The alarm device provides an indication that the electrostatic filter is properly mounted within the air purifier apparatus when energized by the power supply.
