Product Details

Unparalleled Water Purification

Experience the pinnacle of water purification with the ICS-TP, Activated Carbon and Salt-free Softener for Whole House from Cascadian. This advanced system uses activated carbon to remove impurities, ensuring that every drop of water you consume is clean, safe, and healthy. The ICS-TP system is designed to eliminate harmful substances like chlorine, pesticides, and volatile organic compounds, providing you with water that's as pure as nature intended.

Salt-Free Softening for Luxurious Comfort

Say goodbye to hard water problems with our salt-free softener. Unlike traditional systems, our salt-free softener doesn't add sodium to your water. Instead, it uses a revolutionary technology to condition water without the use of salt, preventing scale build-up in your pipes and appliances. This results in softer skin, silkier hair, and longer-lasting appliances, all while being eco-friendly and cost-effective.

Whole House Solution for Ultimate Convenience

The ICS-TP system from Cascadian is a comprehensive solution for your entire home. It's designed to treat all the water entering your house, ensuring that whether you're cooking, bathing, or doing laundry, you're using only the purest, softest water. With easy installation and minimal maintenance, it's the perfect choice for homeowners seeking a hassle-free way to improve their water quality.

      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

      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.
