The rated pore size is for >99.99% collection efficiency for
that size particle and greater. All of these filters have >99%
collection efficiency for particles as small as 0.3 um. The
stated pressure drop is for a 40 mm collection diameter with
an air flow rate of 2 ACFM and barometric pressure of
23.1"Hg. The FWHM is for Po-214 at 7.68 MeV and was
determined using a 25 mm collection diameter and a 25 mm
diameter diffused junction detector with a spacing of 4 mm.
The pressure drop will be higher and the FWHM will be
broader at higher barometric pressures.
