Quality
Purtrex filters are manufactured under a quality management system that has been certified 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.

Certifications
• U.S. FDA 21CFR 177.1520 food contact
requirements
• Article 3 of the EU Framework Regulation No.
1935/2004/EC safety requirements
• EU Plastics Regulation No. 10/2011 (may be
used as intended in compliant EU Member
states)
• USP class VI-121°C Plastics criteria
• NSF 61 criteria
• ISO 9001 criteria

Veolia filter cartridges are designed and
manufactured for resistance to a wide range of
chemical solutions. Conditions will vary with each
application and users should carefully verify chemical
compatibility. Please contact your Veolia
representative for more information.

3 Absolute-rated filters have been designed and tested to reject at least 99% of particles of the listed micron size. Nominal-rated filters have a wider
distribution of pore sizes and therefore a wider distribution of rejected particle sizes. The nominal rating is primarily used to compare efficiencies
across a filter family and between filter manufacturers. Efficiency is dependent on particle shape, size, composition, application, and testing protocol.
