Including filter system and high-performance Calicivirus filter.
Calicivirus is a group of viruses that can enter water supplies when contamination occurs, often tied to human waste. Because these organisms are microscopic, water may appear clear even when it’s a potential concern. In Garnier, homeowners typically learn of viral risks from well testing, advisories, or after a local system issue; knowing how viruses move and how they’re handled helps you feel more secure about water at every faucet.
Viruses don’t show up as sediment, discoloration, or taste, and boiling isn’t a practical whole-house fix. Calicivirus can be introduced through compromised plumbing, backflow, flooding effects, or vulnerabilities in private wells, and it can travel with water through your pipes. A whole-house solution treats water at the point it enters your Garnier home so your kitchen, laundry and baths get continuous protection rather than spot treatments at individual taps.
The single most effective style of whole-house filter for calicivirus is ultraviolet (UV) disinfection. UV systems don’t filter out particles the way carbon does; instead they use a UV lamp inside a stainless-steel chamber to inactivate microorganisms as water flows through. When sized and maintained correctly, UV is a reliable method for virus control and is well suited to homeowners who want ongoing treatment without changing how they use water every day.
UV works best when water is clear enough for the light to pass, so it’s commonly combined with a sediment prefilter, but the UV unit is the primary defense against calicivirus. Performance relies on proper flow rates, a clean quartz sleeve, and routine lamp changes because UV output falls over time. UV adds no chemicals or taste changes, making it a straightforward point-of-entry barrier for Garnier residences, and Mr. Pure Water can help size and install the right whole-house UV system for your household needs.
