5 Stage Standard R/O

The Filtronix 5-Stage Reverse Osmosis System offers proven, reliable reverse osmosis (RO) water filtration below your sink. Usable either standalone or as an add-on to a below-sink, the RO uses multiple filters to treat the presence of aesthetic contaminants, health contaminants, and minerals in the water.

Included with the system is a special 3-tube air gap faucet that requires a 1” – 1.25″ hole in the countertop or sink for installation. Because of the complexity of the system installation (requiring connections to both the water source and the drain), and the large below-sink area required, a licensed technician is required for installation.
