What is G4
G4: Manufactured to European standard EN779:2012
These ratings are determined by adding particles of varying sizes, from .3 microns to 10 microns, into a controlled testing environment. The particles are added upstream of the test filter and a laser particle counter samples the air before it enters the filter and again after it leaves the filter. The two particle counts are compared to calculate the Particle Size Efficiency of the tested filter. Once this is determined, a Parameters chart is used to determine the filters rating.
