VistaPure Replacement Filters. Maintaining the VistaPure system is simle and requires only periodic checks of water quality (with the provided TDS meters) and appropriate filter changes. It's not typically necessary to change all of the VistaPure filters at the same time.
The Prefilter & Polishing filter should be changed at least once per year, and the Deionization and Hyperfiltration filters changed only as needed, as indicated by TDS test.
Your TDS readings determine when it is necessary to change your Hyperfiltration Element or Deionization filters.
Filter Position & Replacement Thresholds
- Prefilter (CVR3251): Replace this filter at least annually, or more often as needed based on local water supply.
- Deionization Filter (CVR3252): Replace this filter and CVR3253 when system-mounted TDS meter "OUT" displays number greater than or equal to 004 ppm.
- Deionization Filter (CVR3253): Replace this filter and CVR3252 when system-mounted TDS meter "OUT" displays number greater than or equal to 004 ppm.
- Hyperfiltration Element (CVR3254): Replace whenever the system-mounted TDS meter “IN” displays number greater than 10% of the TDS of the municipal water supply TO the system, as measured with the included, handheld meter.
- Polishing Filter (CVR3255): Replace this filter at least annually, or more often as needed based on local water supply.
