Purtrex depth cartridge filters are a patented thermally bonded filter for all-around industrial use in plating, chemical filtration, and potable water. Purtrex is an exceptional value for applications where long life, high purity, and low change-out frequency are desired.

• Exceptional value for general applications
• Progressive graded density captures particles throughout the entire filter
• No surface blinding (surface blinding causes flow reduction, which increases filter change outs)
• Inert material means broad chemical compatibility
• Exceptional dirt-holding capacity
• Pure 100% polypropylene construction
• No wetting agents, solvents, antistatic agents, or binders
• Incinerates into trace ash with no hazardous volatiles for easy disposal
• Made in the USA
