Purtrex Cartridge Filters

Features and Benefits

The Purtrex depth filter is an exceptional value for generalapplications where long life, high purity and low change-outfrequency are required. Produced through GE’s patented meltblown microfiber technology, Purtrex is a 100% purepolypropylene depth filter with exceptional dirt-holding capacity. Purtrex’ true-graded density filter matrix (lower density at thesurface of the filter with progressively higher density toward thecenter) captures particles throughout the entire filter depth. Thistranslates to longer life and fewer change-outs than existing string-wound or resin-bonded filters. Purtrex contains no wetting agents, solvents, antistatic agents orbinders, and meets the requirements of the FDA for food andbeverage contact. The filter incinerates to trace ash for easydisposal.
