Including filter system and high-performance Calicivirus filter.
Calicivirus refers to a family of viruses that can enter household water when contamination happens, commonly via contact with human waste. Because these viruses are invisible, your water may appear clear even if a risk exists. In Athena, homeowners typically hear about viral concerns through a well test, a utility advisory, or after an event like flooding or a system issue nearby. Learning how viruses behave and how they are addressed can give you more confidence in the safety of your water throughout the house.
Viruses such as calicivirus aren’t detectable by sight or smell, and boiling every tap isn’t practical for whole-home protection. They can be introduced by compromised plumbing, backflow, floodwater, or vulnerabilities in private wells, and can travel with water into bathrooms, laundry areas, and kitchens. Treating water at the point it enters your Athena home protects every fixture at once, ensuring consistent coverage rather than relying on point-of-use fixes.
For calicivirus, the most effective single whole-house treatment is ultraviolet (UV) disinfection. Rather than filtering out particles like carbon media, a UV system uses a high-intensity lamp inside a stainless steel chamber to inactivate microorganisms as water passes through. When correctly sized and maintained, UV is a widely used method for virus control and suits homeowners who want continuous, automatic protection without changing how they use water in their Athena residence.
UV treatment performs best when the incoming water is clear enough for the light to reach microbes, so it’s commonly paired with a sediment prefilter ahead of the UV chamber. Long-term effectiveness depends on matching the unit to your home’s flow rate, keeping the quartz sleeve clean, and replacing the lamp on schedule as output diminishes. UV doesn’t add chemicals or alter taste, making it a simple, clean barrier at the point of entry, and Mr. Pure Water can help Athena homeowners select and size a whole-house UV system based on household use and water conditions.
