Including filter system and high-performance Norovirus filter.
Norovirus is a highly contagious virus that commonly causes sudden stomach and intestinal illness. When it turns up in water, the source is typically sewage-related or from a failure in treatment or distribution rather than something naturally present in the supply. Because viruses are microscopic, you can’t judge safety by taste, smell, or how clear the water looks. Garnier homeowners most often discover a potential problem after a municipal advisory or a private water test that includes microbial screening.
Water can become a route for norovirus when sanitation systems break down — for example during pipe repairs, pressure loss, or issues with wells and septic systems. Even though person-to-person contact and contaminated food are more common ways to catch norovirus, water still plays a part in everyday tasks like drinking, brushing teeth, making ice, and washing dishes. That’s why many Garnier families choose a whole-house barrier instead of treating only one faucet, so the same protected water reaches bathrooms, kitchens, and laundry.
The most effective single-filter option for addressing norovirus at home is a whole-house ultraviolet (UV) disinfection system. Rather than trapping viruses, UV uses germicidal light inside a sealed chamber to inactivate microorganisms as water passes through. When sized and maintained correctly, UV is widely used for virus control because it provides continuous treatment without chemicals — a practical choice for Garnier homeowners who want whole-home protection where water enters the house.
UV works best when incoming water is clear enough for the light to reach microbes, so whole-house installations often include a sediment prefilter to remove cloudiness. Pairing a prefilter with the UV stage keeps the disinfection reliable while keeping treatment focused on a single, proven method for viruses. Mr. Pure Water can size a Garnier home system to meet your peak flow needs so showers, appliances, and multiple bathrooms stay protected; with regular lamp changes and simple maintenance, UV provides dependable whole-home defense against norovirus concerns.
