Under Sink Reverse Osmosis

With a US Water RO system, you can have peace of mind in knowing that your water quality will be unparalleled. We keep going where other systems stop because nobody cares about your water like we do. What makes US Water Reverse Osmosis Systems different are a number of things, including the following:

  • All of our systems are BPA-Free
    You can rest assured that we will not use products that contain BPA or other harmful chemicals.
  • All of our systems use American Made Filters and Membranes
    For your drinking water safety, we don’t cut corners by using cheap foreign imitations.
  • All of our systems use the highest quality FDA Approved and NSF and WQA Certified components
    Our quality is unequaled.
  • All of our systems are Made in the USA
    Of course not every part is American made (that's impossible), but our product is built by Americans with as many American Made Parts as possible.

We really have 3 systems, the Galaxy, Aquapurion and the Cobalt. The Cobalt is strictly for city water and has enhanced Chloramine and Fluoride removal. Both the Cobalt and Aquapurion are available with the High Pressure Non-electric Permeate Pump Option which we recommend if you are hooking up to an icemaker. If you are not sure which model you need, call one of our Certified Water Specialists. We will be happy to assist you.

If you are looking for bottled-quality water straight from the tap, you are probably looking for an under sink reverse osmosis system. These units are commonly just called RO systems and they are the ultimate in water filtration. Reverse osmosis not only provides clean and safe water that the entire family will love, but it also saves money by eliminating the high cost of bottled water. All under sink RO systems from US Water include the drinking water faucet and filters.
