Compare US Water RO Systems
US Water Systems offers a full-line of under sink reverse osmosis systems, all assembled in the USA. We start with the US Water Galaxy economy under sink RO, which delivers great-tasting drinking water without breaking your budget. All of these filter systems use NSF and FDA-approved materials, are BPA Free, and are built to last for years. They all use industry standard filters, meaning that you don’t have to pay an arm and a leg to replace them. Each system comes with standard chrome faucet and 4.5 gallon storage tank, with 1/4" tubing throughout. They are also backed with a 2-year warranty!
If you want a premium reverse osmosis system with a great warranty, then you will want to look at our professional-grade RO systems. In addition to using all NSF and FDA approved materials that are BPA free, they also have a full 3/8” flow from the tank to the faucet and American-made filters and membranes. Additionally, they come with a selection of optional storage tanks.
If you are attaching your RO system up to an icemaker, then you will want one of our High-Pressure Systems. These reverse osmosis under sink units use a non-electric permeate pump that saves up to 80% on waste water and delivers the same pressure as what you have coming in. This is the system you will likely want to use if you are remote installing or have multiple outlets. A high pressure unit is extremely important if you are attaching your reverse osmosis system to an icemaker.
We also have high-volume light commercial systems, which are ideal for homes with two or more refrigerators, icemakers, sinks, and humidifiers. They do require more space because they have bigger tanks, filters, and membranes, so most people install them in a garage, basement, or utility room and run lines to each outlet. Light commercial systems are also popular with people who brew beer or have aquariums.
US Water Systems stands behind every product we sell. We are so confident you will love our under sink reverse osmosis systems that we offer a 30 day money-back guarantee (ask for details).
What is Reverse Osmosis?
Reverse osmosis is a filtration method that passes water through a filter membrane that has pores that are so small, only pure water is able to get through. Other contaminates are physically too large to pass through the membrane, so they do not enter the drinking water supply.
