Please note that it’s NOT typically necessary to change all of the filters at the same time. The Prefilter & Polishing filter should be changed at least once per year, and the Deionization and Hyperfiltration filters only need to be changed on an as-needed basis, as indicated by TDS test. Be sure to watch our separate video on filter-performance testing, as checking your water quality monthly will help you keep ahead of required filter changes.
At least once per year and after filter elements are replaced, you should check the air pressure of the system’s water-storage tank, and sanitize the system with unscented chlorine bleach.
