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.

In 2014 we implements several more product advances that once again changed cartridge based water treatment. 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 or even better 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.

Good To Know

To use this table start by finding the part number of your treatment system. The part number can be found by looking at the label on the bracket. The label will show you both the system part number and the replacement filter part number.

To find your replacement filter kit

• Find the part number (the one without the letter K on the then of it) and locate in column 1 of the table below.
• The current system part number is shown in column 2.
• Any change in the number of filters in the system is found in column 3.
• The current replacement filter kit part number will be found column 4, this is the one you need to order to keep the same quality treatment.
• If your older system uses more replacement filters than the new replacement filter kit simply leave one of your existing sumps empty.
