Reset filter F1 menu


Does anyone know if we can reset the filter timer in the F1 menu. My first filter lasted about 20 hours but after changing it the new one runs about 2 minutes before the change filter light comes on again and the laser stops, tried another new filter but still get the same result and a message on my pc saying buy filters. Not sure how the filter is controlled. Air flow, Fan power consumption, or internal timer. Any descriptions of the different commandes available on the F1 screen would also be appreciated.
