Including filter system and high-performance Calicivirus filter.
Calicivirus refers to a family of viruses that can enter household water when contamination occurs, often linked to contact with human waste. Because these organisms are far too small to see, water that looks clear can still pose a concern. In Franjo, homeowners typically learn about viral risks from a well test, a utility advisory, or worries after flooding or a plumbing issue; understanding how viruses move and how they’re treated is the first step toward greater confidence in your water.
Viruses don’t produce visible sediment, rust, or an off taste, and boiling every outlet in a house isn’t realistic for everyday use. Calicivirus may enter a home through compromised plumbing, backflow, floodwater, or well vulnerabilities and can travel with the water into sinks, showers, and appliances. A whole-house solution treats water at the point of entry so every tap in your Franjo home — from the kitchen to the laundry room — gets the same protection.
For calicivirus, the most effective single whole-house option is ultraviolet (UV) disinfection. Rather than filtering out particles, a UV system passes water through a stainless-steel chamber where a UV lamp inactivates microorganisms as water flows by. Properly sized and maintained, UV is a widely accepted method for virus control and suits homeowners who want continuous, low-impact treatment without changing daily water use.
UV works best when water is clear enough for light to penetrate, so it’s commonly installed with a sediment prefilter ahead of the UV chamber; the UV unit remains the primary defense against calicivirus. Performance relies on correct flow rate, a clean quartz sleeve, and scheduled lamp replacement because UV output falls with time. UV doesn’t add chemicals or alter taste, making it an unobtrusive whole-house barrier — Mr. Pure Water can help Franjo homeowners pick the right-sized UV system for their house and local water conditions.
