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.
