Integrity Test Information
Representative sample cartridges are factory tested for
integrity before shipment. Field duplication of these tests is
not practical because of the absence of commercial portable
testing equipment.

steel support ring is required.
Chemical Sanitization
Carried out using industry standard concentrations of
hydrogen peroxide, paracetic acid, sodium hypochlorite,
and other selected chemicals.
Total Performance
Critical Process Filtration, Inc. is a vertically integrated
manufacturer of filtration products to industries in which
filtration is considered a critical part of the manufacturing
process. We supply a complete line of products and services to
help you cost effectively satisfy all your filtration requirements
from a single source.
Electronics Grade
EPD Depth Filter Cartridges are designed to meet the special
needs of the electronics and high-purity chemical industries.
Raw materials of construction were specifically chosen to be
chemically compatible and to produce minimal extractables
when exposed to typical process chemicals and solvents.
Each cartridge module is pulse power flushed until the rinse
effluent reaches 18+ megohm-cm and less than 3 ppb TOC.
Representative cartridge modules from each manufacturing
lot are also integrity tested to assure lot quality. EPD cartridges
are rated at 99.9% efficiencies at the rated pore size. Our design
criteria and special procedures allow us to provide the highest
quality electronics grade cartridges.
