The H2O International US4-13 under-sink water filter replaces and retrofits the discontinued NSA 100S and is an excellent replacement for the now discontinued NSA 100SX. The US4-13 uses the same size tubing and fittings as both NSA models.
This system connects to your existing sink faucet and flows up to 2 gallons per minute. The filter will remove chlorine, bad taste, odor, lead, and trace chemical contaminants from your family’s water.
Our company has been offering this model for over 20 years, and thousands of happy customers use it. It’s our most popular under-sink filter!
