Including filter system and high-performance Calicivirus filter.
Calicivirus refers to a family of viruses that can enter household water when contamination happens, often via contact with human waste. Because these agents are microscopic, water can appear perfectly clear while still posing a risk. In Glass, homeowners commonly learn about viral concerns from well testing, a local advisory, or after nearby system problems; understanding how viruses behave and how they’re managed helps you feel safer at every tap.
Viruses like calicivirus aren’t visible, don’t affect taste or smell, and aren’t something you can practically address by boiling for the whole house. They can enter plumbing through backflow, flooding, compromised pipes, or vulnerable wells and travel with the water. Even treated supply lines can be exposed if there’s a pathway for contamination. Installing protection where water enters your Glass home treats every outlet at once — kitchen, laundry and baths — so the whole house is covered.
The most effective single style of whole-house filter for calicivirus is an ultraviolet (UV) disinfection system. Rather than trapping particles like carbon media, UV uses a lamp inside a stainless-steel chamber to inactivate microorganisms as water flows through. Proper sizing and routine upkeep make UV a common choice for virus control because it addresses microbes that standard filters can’t, and it delivers continuous treatment without changing how you use water in the home.
UV systems perform best when water is clear enough for the light to penetrate, so they’re commonly installed after a sediment prefilter; the UV unit itself is the key barrier against calicivirus. Long-term effectiveness depends on correct flow rate, keeping the quartz sleeve clean, and replacing the lamp on schedule since output fades with time. UV adds no chemicals or taste changes, making it a simple, effective point-of-entry solution — and Mr. Pure Water in Glass can assist with sizing and selection based on your household’s needs.
