Over the long lifespan of your residential salt-free water treatment system, you’ll need to replace filters from time to time. This ensures optimum performance and results. We recommend switching out your salt-free water filters every year—or earlier if you notice any performance issues. Our filter replacements are top of the line and can remove sediment and particles down to 5 microns! Saltless water filters aren’t just a great treatment solution for homes; they're also capable of treating water for businesses, such as offices and restaurants. Order your replacement salt-free water filters today here at Cascadian Water. For all other questions and concerns, please contact our friendly team!

To save you time, money, and hassle we've added a Subscribe and Save 10% option for all of our replacement filter cartridges. To learn more, click here.
