H₂O International US4-13
Under Sink Model Water Filter
Model #: H2O-US4-13

The H₂O US4-13 under sink filter replaces and is a perfect retro fit for the discontinued NSA 100S. This model is also an excellant replacement for the now discontinued NSA 100SX. The US4-13 uses the same size tubing and the fittings as both the NSA models.

This system connects inline with your existing sink faucet and flows @ 2 gallons per minute, so there is usually no change in flow. The filter will remove chlorine, bad taste and odor from your family's water. The US4-13 also removes lead and does a better job of chemical contaminant removal than a system that uses carbon only, such as the now discontinued NSA models.

Utilizing Granular Activated Carbon and patented KDF media, this unit is bacteriostatic, meaning it will inhibit bacteria growth from within the unit. KDF also enhances the carbon's ability to remove chemical contaminants by removing most of the Chlorine from the water before the water contacts the carbon. With the carbon not burdened with chlorine removal, it can perform higher levels of filtration such as chemical contaminant reduction.

Use the H₂O US4-13 for all kitchen water needs including drinking water, ice, juice concentrates, coffee, tea, cooking, pets, plants and more. Available at a fraction of the cost of bottled water, this easy to install under sink system installs easily with 3/8 push in fittings or compression fittings if requested. The time tested system produces 25,000 gallons of chlorine-free, quality drinking water before a replacement is needed.
