Detective quantum efficiency. The detective quantum efficiency (often abbreviated as DQE) is a measure of the combined effects of the signal (related to image contrast) and noise performance of an imaging system, generally expressed as a function of spatial frequency.
The published MPR Rating numbering system is a scale of 0 2700, with their highest published furnace filter equaling a MERV 13. FPR Rating, or air Filter Performance Rating, is a grading system that uses a color/number system on a scale of 4 (green circle) to 10 (blue circle). Some of their air conditioner filter descriptions refer to the MERV Rating and the MPR Rating, but don't always agree. Its important to note that the MERV Rating is the MINIMUM initial efficiency rating. Its the efficiency rating given to an air conditioner furnace filter when it is brand new, as the new air conditioner furnace filter traps more debris, it actually and somewhat surprisingly, becomes more efficient at trapping particles as time goes by.
