The Purtrex depth filter, is an exceptional value for general applications where long life, high purity and low change-out frequency are required. Produced through Suez's patented melt blown microfiber technology, Purtrex is a 100% pure polypropylene depth filter with exceptional dirt-holding capacity. Purtrex’ true-graded density filter matrix (lower density at the surface of the filter with progressively higher density toward the center) captures particles throughout the entire filter depth. This translates to longer life and fewer change-outs than existing string-wound or resin-bonded filters. Purtrex contains no wetting agents, solvents, antistatic agents or binders, and meets the requirements of the FDA for food and beverage contact. The filter incinerates to trace ash for easy disposal.

Purtrex filters are available the following pore size nominal micron ratings: 1, 3, 5, 10, 20, 30, 50 and 75 microns.
Purtrex cartridge filters are made from thermally bonded fibers of polypropylene. Suez certifies that it uses no resin binders, lubricants, antistatic or release agents, in the manufacture of these filter cartridges. The resin used for manufacturing the filter media meet the food contact requirements of the U.S. FDA 21CFR 177.1520. Purtrex cartridge filters meet the safety requirements of Article 3 of the EU Framework Regulation No. 1935/2004/EC and may be used as intended in all of the EU Member states in full compliance with the EU Plastics Regulation No. 10/2011. Purtrex cartridge filters meet the criteria for USP class VI-121’C Plastics.
Suez 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.
The Purtrex element is tested and certified by NSF International against NSF/ANSI Standard 42 for material requirements only. Ordering Information
