Including filter system and high-performance Calicivirus filter.
Calicivirus refers to a family of viruses that can appear in water following contamination, most commonly from contact with human waste. Because these pathogens are microscopic, water can appear clear while still posing a risk. Lewis homeowners often learn about viral concerns from well tests, utility notices, or after a local plumbing or system issue; knowing how viruses behave and how they’re treated can help you feel safer at every faucet in your house.
Viruses like calicivirus can’t be seen, smelled, or fixed by simple boiling for an entire household supply, and they move with water when there’s a pathway for contamination. Events such as backflow, flooding, compromised plumbing, or well vulnerabilities can introduce viral contamination and allow it to travel through your system. That’s why many Lewis residents prefer a whole-house strategy that treats water where it enters the home, protecting kitchens, bathrooms and laundry all at once.
For calicivirus, the most effective single whole-house option is ultraviolet (UV) disinfection. UV units don’t filter out particles the way carbon does; instead a UV lamp inside a stainless steel chamber inactivates microorganisms as water passes through. When a UV system is sized and maintained correctly, it’s a proven method for targeting viruses that conventional media can miss, and it provides continuous treatment without changing daily water use for Lewis households.
UV systems work best when the incoming water is clear enough for the light to penetrate, so they’re commonly installed after a sediment prefilter; however the UV unit remains the primary treatment for calicivirus. Reliable performance depends on matching the system to your flow rate, keeping the quartz sleeve clean, and replacing the lamp on schedule as output decreases over time. UV doesn’t add chemicals or alter taste, making it a straightforward point-of-entry barrier — Mr. Pure Water can assess your Lewis home and recommend the correctly sized whole-house UV setup.
