3M Water Filtration CFS110 5 mic 2-5/8 x 9-3/4 Features:

  • Consistent particle removal efficiencies with sharp cut-offs,
  • Extended cartridge life,
  • Ability to withstand high temperatures and elevated differential pressures,
  • Broad chemical compatibility, and
  • Consistent batch to batch filtration characteristics.

The exclusive CUNO manufacturing process produces a rigid, polypropylene, progressive porosity structure that eliminates by-pass and the unloading characteristics of soft and easily deformable, competitive filter cartridges such as spiral wound and string wound cartridges. The design of CFS110 provides a family of filter cartridges that offer distinct advantages:

3M Water Filtration filter cartridges are the product of continuous refinement of manufacturing and fiber technologies.  The grooving of the outer surface significantly increases the filter's effective surface area, and increases the contaminant holding capacity.

Note: We recommend replacing the sediment prefilters CFS8504-A (10 micron) with the 5 micron CFS110 to extend the life of carbon filters and equipment downstream.
