The science inside matters.

Why is it important to properly shut down and restart your 3M Water Filtration System? Inside your cartridge is our Integrated Membrane and Pre-Activated Carbon Technology (“I.M.P.A.C.T.”). This three stage system provides filtration you can count on to help reduce contaminants that may be in your water—and performing a proper shutdown is a great way to help keep it operating as intended.

  • ● Sanitary Quick Change

    Encapsulated cartridge design allows for fast and easy cartridge change-outs without contamination.

  • Stage 1: Pre-Filtration

    Non-woven filtration media that reduces larger size particles to help increase sediment holding capacity of the filter.

  • Stage 2: Fine Filtration

    3M proprietary two-zone microporous pleated membrane that reduces 99.99% of protozoan cysts and helps provide excellent sediment life with minimal pressure drop.

  • Stage 3: Final Filtration

    Activated Carbon Filtration; 3M carbon block technology for reduction of lead, chlorine and odour and for improved taste.
