Reverse Osmosis Systems for Home & Light-Commercial Use
A reverse osmosis (RO) system pushes water through a semipermeable membrane to strip out dissolved solids, lead, fluoride, sodium, nitrates and more — delivering bottled-quality drinking water straight from your tap. We carry 4- and 5-stage under-sink systems plus light-commercial units from Watts, Pentek, PureT and Isopure Water, rated from 50 GPD up to 380 GPD.
How to choose an RO system
Match GPD to your demand. 50 GPD suits most households; larger families, offices, or coffee and ice applications do better with 100 GPD or light-commercial 380 GPD units.
Count the stages. 4-stage systems (sediment + carbon + membrane + polish) cover most needs; 5-stage adds a carbon or remineralization stage for taste.
Standard vs. Kwik Change. Twist-in "Kwik Change" cartridges make annual swaps tool-free; standard housings cost less and use widely available cartridges.
Tank & faucet. Metal or plastic pressurized tanks store finished water — check whether the system includes a dedicated faucet or sells it separately.
