  • Commercial & hospitality: protecting coffee machines, ice makers, and other equipment from sediment in cafés, restaurants, and similar settings.
  • Light industrial & process water: general industrial use, chemical filtration, and plating bath applications where a durable, chemically-compatible cartridge is needed.

Frequently asked questions

Purtrex uses a true graded-density spun polypropylene matrix, with coarser fibres at the surface and progressively finer fibres toward the core, giving high dirt-holding capacity and long service life.

Both are genuine Veolia products, 100% polypropylene, with no wetting agents, solvents, or binders.
