Quality Assurance & Traceability
Memtrex MP filters are manufactured under a
quality management system that has been certi-
fied to meet ISO 9001 standards. Each filter is
assigned a lot code to ensure traceability of the
data and materials used in the manufacturing
process.
Integrity Testing
For assured quality and performance, the subas-
semblies used to construct the Memtrex MP filters
are individually integrity tested.
Pore Size Rating Specification
0.03 µm ≤ 45 cc/min at 50 psig (3.4 bar)
0.1 µm ≤ 45 cc/min at 50 psig (3.4 bar)
0.2 µm ≤ 19 cc/min at 30 psig (2.1 bar)
0.45 µm ≤ 16 cc/min at 20 psig (1.4 bar)
0.65 µm ≤ 12 cc/min at 13 psig (0.9 bar)

Filtration Efficiency and Microbial
Retention
Memtrex MP filters are absolute rated. Repre-
sentative filters meeting integrity test specifica-
tions have demonstrated ≥ 99.9% initial particle
retention efficiency at the rated pore size based
on ASTM F661 test methodology.
Memtrex MP filters have good microbial retention
for reliable bioburden control. Representative
filters meeting integrity test specifications have
demonstrated the following microbial retention
characteristics based on ASTM F838 test method-
ology.

Sanitization
Memtrex MP filters may be autoclaved or in situ
steam sterilized. Filters which are steam sterilized
must have Z or Q adaptors.

Exposure
Steam 125°C (257°F) 10 hours
Alternatively, the filters may be sanitized with com-
patible chemical agents.
