ICS-SP Water Treatment System

The ICS-SP is a cartridge-filter based water treatment system engineered to produce high-quality water for every use in home or business. It is two high-performance treatments in one small wall-mounted system and an excellent choice for well water.

Enjoy Two High Performance Treatments in one filter

The first treatment is a high capacity multimicron sediment filter. This filter removes particles down to 5 micron to clarify the water and protect downstream treatment and the plumbing, fixtures and appliances.

The second treatment is PolyHalt® media where the water is softened without salt and further conditioned to treat silica and blue copper staining which extends the life of plumbing, fixtures, appliances, windows and glassware etc., by protecting them from damage caused by untreated water.
