Abstract: A magnetic debris level measuring device for a magnetic filter is disclosed. The magnetic debris level measuring device includes a magnetometer and a temperature sensor. The temperature measured by the temperature sensor is used to calculate a corrected magnetometer reading, which in turn can be used to determine the amount of captured magnetic debris held within the filter. The device has a stored threshold for the corrected magnetometer reading, and when the corrected magnetometer reading crosses the stored threshold a notification is issued that the filter is full. If it is detected that debris continues to be captured after the ‘full’ notification has been issued, the stored threshold will be updated accordingly.

Abstract: An air purification device includes a controller configured to perform a normal discharge operation in which a discharger generates streamer discharge to purify air, and an emergency discharge operation in which, in order to remove substances, which are components contained in air, adhering to electrodes of the discharger due to the normal discharge operation, a higher voltage than that in the normal discharge operation is applied to the electrodes to cause the discharger to generate spark discharge. The controller adjusts an application voltage such that a current value between the electrodes is maintained constant, and the upper limit V of the application voltage is set at a value greater than an inter-electrode distance of d×1.2 (V≧d×1.2).
