I live in a home where a water filtration system was already installed. How do I know which replacement filter to use?

You can consult the user guide if the previous owner left it behind. If not, call us directly and speak to a home water expert who can verify the correct replacement filter for your system.

How frequently do I need to change my water filter cartridges?

The exact frequency of water filter cartridge changeouts will vary depending on your water treatment solution. Many filters either last 6 months or a full year. Consult your user guide for the correct timing for replacing your water filter cartridge. In some cases, your water quality or sediment levels will require you to replace cartridges more frequently.

Why do I need to regularly change my water filter?

Over time, the media that captures contaminants will fill up and become less effective. Your treatment solution will not operate at the indicated levels if you do not replace your filters. Regularly changing your water filter ensures your water is filtered for contaminants at optimal rates.
