ICS-STP Water Treatment System
The ICS-STP is a cartridge-filter based water treatment system engineered to produce high-quality water for every use in home or business. It is three high-performance treatments in one small wall-mounted system. The ICS-STP combines our ICS-SP and ICS-TP treatment systems and is one of our top sellers. It is an excellent choice for city or well water.
Contains Two Filters:
Filter One:
The first filter 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.
Filter Two:
The second filter is a top quality activated carbon filter combined with Cascadian PolyHalt®. It is specially designed to reduce the total number of filters required for maximum treatment without increasing the overall size of the treatment system.
Water is first treated by passing through the activated carbon component to reduce chlorine, improve taste and odor, and reduce volatile organic compounds (VOC's).
After carbon treatment the water passes through PolyHalt® media where it is 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.

Small Size Means Flexible Install
Don't sacrifice precious garage space. The whole house filters from Cascadian are much smaller, and take up no floor space.

It's important to note that products featuring PolyHalt® - identifiable by a 'P' in the part number - may be damaged by contaminants such as hydrogen sulfide or tannins. To ensure optimal performance of PolyHalt®, these contaminants must be adequately removed from the water.
Our ICS-H product offers a suitable option for pretreatment for hydrogen sulfide. Utilizing ICS-H will aid in eliminating these harmful substances, thereby preserving the efficiency and extending the lifespan of your PolyHalt® products. Always remember to pre-treat your water with ICS-H when necessary to ensure the best performance and durability of your PolyHalt® system.
