ICS Part Number History

Since first being introduced in 2011 we have made improvements to our ICS Systems.

If you are unable to find your part number on our website here's a helpful resource.

Some of these changes allow us to build treatment systems with fewer filters. Others enable us to eliminate low flow rate versions and use high flow filters for all systems.

These improvements reduce total environmental impact and physical size of treatment systems while providing the same functionality.

To reflect these improvements, we’ve created new part numbers and specifications.

We understand when older Cascadian ICS Systems need new filters customers need to know what new part number they need to order. For that we’ve made this handy cross reference.
