Take your home water purification to the next level with the UltraFlo™ Under the Sink Water Filtration Kit. Removes bacteria, virus, protozoan, as well as many water borne toxins, such as lead, fluoride, arsenic, chromium, mercury, zinc, perchlorate, cadmium, and barium from your tap water. Fits most under-sink sump whole house filtration systems. Ideal system for RV under sink water filter, Campers, and Van Conversions. The UltraFlo™ Filter has been tested and certified using the "End of Life" method. Simply put, all Sagan Life® water purification products have been independently tested until they cease to work. Which is why we know the UltraFlo™ purifies up to 2000 gallons of water, and exactly what it removes. Many under the sink filtration options are not effective at removing contaminants, and are often designed only to improve the taste of drinking water, leaving tens of millions of U.S. households with contaminants in their water. This sink water filtration system makes sure your water is safe, pure, potable and great tasting! EPA Est.#94138-ID-1
