Real Protection from Contaminants. The Essential RO3 was designed from the ground up with our full bed depth, fully compliant, USA made filters to handle difficult contaminants like chloramine (chlorine and ammonia compound). It is a new breed of reverse osmosis that effectively protects you from chloramine, chlorine, THMs, VOCs, PFAS, lead and cysts.
Our filtration appliances are in use worldwide by hospitals, medical centers, health and fitness centers, military, professional athletes, and thousands of personal homes worldwide.
Healthier Home & Lifestyle. All our sink filtration systems are designed to prevent you and your family from drinking various contaminants and carcinogenic (cancer-causing) chemicals. Enjoy chlorine-free, healthy, filtered water – use for drinking, filling up a pet's water bowl, watering plants, making tea and coffee, or filling up the humidifier with chlorine-free filtered water.
Easy to Install & Self-Maintains. Our RO3 is a hassle-free, user-friendly system that only requires a filtration replacement about once per year (based on your local water conditions and usage).
