Including filter system and high-performance Calicivirus filter.
Calicivirus refers to a family of viruses that can enter water supplies when contamination happens, commonly via contact with human waste. Because these viruses are invisible to the eye, water in Two Egg may look clear while still posing a risk. Homeowners typically learn about viral concerns from a local advisory, a private well test, or after a nearby system upset or spill; understanding how viruses behave and are treated is the first step toward feeling secure at every tap.
Viruses like calicivirus don’t present as sediment, rust, or taste issues, and boiling every faucet is impractical for whole-home use. They can enter plumbing through damaged seals, backflow, flooding, or well vulnerabilities and travel with water into sinks, showers, and laundry. Even if public treatment is in place, pathways for contamination can occur, which is why a whole-house strategy in Two Egg treats water at the point of entry so every fixture in your home is covered consistently.
For calicivirus, the most effective single whole-house option is ultraviolet (UV) disinfection. UV systems don’t remove particles the way carbon filters do; they use a UV lamp inside a stainless steel chamber to inactivate microorganisms as water passes through. Properly sized and maintained UV is widely relied on for virus control because it addresses contaminants that standard media can’t, making it a practical choice for Two Egg homeowners who want continuous treatment without changing daily water use.
UV works best when water is clear enough for light to penetrate, so a sediment prefilter is commonly paired with the unit, while the UV lamp provides the core protection against 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 diminishes over time. UV adds no chemicals or taste changes, offering a simple point-of-entry barrier—Mr. Pure Water can help Two Egg homeowners select and size the right whole-house UV system for their property and water conditions.
