Nominal Micron Rating	Particulate Removal Efficiency
	90%	99%	99.9%	99.99%
	Beta Ratio
	10	100	1,000	10,000
0.1	0.1	0.45	0.8	1.0
0.2	0.2	0.6	1.0	2.0
0.45	0.45	1.0	2.0	3.0
1.0	1.0	3.0	7.0	10.0
3.0	3.0	7.0	10.0	15.0
10.0	7.0	10.0	15.0	25.0
30.0	30.0	40.0	50.0	60.0

Ratings are based on laboratory tests using AC Fine Test Dust and Latex Spheres in water at a flow rate of 2.5 gpm per 10 inch cartridge at room temperature. Field results will be influenced by the type of fluid and contaminant as well as flow rate and temperature.

BETA RATIO is an alternate method of expressing efficiency. Beta= 1/(1-Efficiency)
