The AquaCera NilusTwo Under-Counter Nitrate Reduction Water Filter System is a dual-stage, in-line pressure filter system that connects to your cold water line. The compact design will fit in small, under-sink areas.

Constructed of durable polypropylene, the filter housing holds two replaceable filter elements. A filter element designed specifically to reduce arsenic, the A-3 Nitrate Reduction Imperial OBE Filter, is capable of reducing arsenic levels in your drinking water by as much as 95%. This dual-stage arsenic filter system comes with two filter elements that include the A-3 Nitrate Imperial OBE Reduction Filter Element along with your choice of a CeraUltra Imperial OBE, CeraMetix Imperial OBE , and AquaMetix Imperial OBE filter. By combining two separate filters in one filter system, your water is filtered twice. This results in near zero arsenic concentrations and greatly reduced concentrations of most other drinking water contaminants.

The system includes a mounting bracket and screws, and the inlet and outlet use push fit connectors for easy installation. An optional Do-It-Yourself installation kit that includes the parts needed for most installations is available. The DIY kit includes a faucet connector, EZ Adapter, and 3/8” tubing for typical installation. The DIY kit also is available in your choice of either the Standard, Modern or Classic faucet version with chrome or brushed nickel finish.
