Product Details

ICS-STPK Cartridge Filter Replacement Kit

The ICS-STPK cartridge filter replacement kit is designed specifically for the Cascadian ICS-STP water treatment system and is perfect for every use in whole home or business. It is an excellent choice for city or well water. 

Contains Two Filters:

Filter One:

The first filter is a high capacity multimicron depth 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 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.

          FAQs

          Where does ICS go in my Home?

          Where it can fit, and where it can easily get access to your home's water source. This is typically a garage, crawlspace, or even a closet. If you have questions a plumber would be able to help you find the best spot. During maintenance you'll need to fit a bucket and have enough space to turn the sump wrench which comes with your system.

          How often do I replace the filters?

          Most people replace their filters once per year, or sooner if they start seeing issues with their water again. Learn about water issues here

          A great system

          The community well water at my get away house was safe but incredibly hard and tasted terrible. The filter system makes the water tasteful and refreshing. The annual filter change is easy and takes less than 30 minutes. Highly recommended.

          NEW SHOP/OFFICE WATER TREATMENT

          WITH OUR NEW OFFICE SHOP COMPLEX WE WERE HAVING SCALING ISSUES FROM THE INCOMING WATER COMPANY WATER DELIVERY. IT WAS CAUSING SCALING AND BUILDUP OF ALKALYN RESIDUAL CAUSING A DECREASE IN LINE PRESSURE AND SHUT DOWN OF SUCH THINGS AS OUR ICE MACHINE. SINCE THE INSTALLATION WE HAVE SEEN VERY LITTLE RESIDUAL BUILDUP OF SCALE. ALSO WITH THE ICE MACHINE, THE ICE SEEMS TO BE CLEARER PRODUCT THAN BEFORE. AT THIS POINT I RECOMMEND INSTALLTION OF THESE UNITS.

          Hey Larry, thanks for sharing your experience! We're delighted to hear that our ICS-STP system helped tackle the scaling issues in your new office shop complex. It's especially great to know that the ice from your machine looks clearer now! Your recommendation means a lot to us. Let us know if you need any further assistance. Best wishes!
