Under Sink Reverse Osmosis

With a US Water Systems™ RO, 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 Systems™ 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 components - They are all FDA NSF and WQA Compliant.
  • We Have RO’s that are assembled in the USA - That means that they have a variety of components sourced from overseas, but with American-Made filters
  • The All-American Reverse Osmosis Systems are the only ones 100% Made in America - Every single part is Made in the USA!

Quality That Lasts

We have five (5) systems which are assembled in the USA with a variety of Global parts, but they do use 100% Made in USA Filters and Membranes. Those five are the Galaxy, Aquapurion, Aquapurion High Pressure, Cobalt, and the Cobalt High-Pressure system. 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. 

Made in America Systems – We have four (4) “Made in America” Systems which are 100% sourced from American Parts. They are the 5-Stage All American RO, the 5-Stage High-Pressure RO, the 6-Stage All American RO with Livation Hydration Alkaline Chamber, and the 6-Stage High-Pressure All American RO with Livation Hydration Alkaline Chamber 

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. 

The Benefits of an Under Sink RO System 

Reverse Osmosis is the best solution for providing quality drinking water at home, and this filtering method is very effective for reducing a range of contaminants. Using an RO water filter will dramatically improve the taste, color, and odor of your water. Most under sink reverse osmosis systems include a sediment pre-filter that traps fine suspended materials that could cause clogs and a carbon pre-filter to remove chlorine and other contaminants that may damage RO membranes. A post-carbon filter is usually added to polish the water. 

Typical Contaminant Removal


How Often Do I Need to Change My Under Sink Reverse Osmosis System Filters? 

Most reverse osmosis filters need to be changed every six to twelve months. If you have a water softener or well water treatment system, however, you may end up changing the filters more or less frequently. 

How Much Is an Under Sink RO System? 

US Water Systems is proud to offer top of the line reverse osmosis under sink systems for a little over $200. These systems are built to last, and are easily afforded on most family incomes. We also offer a wide range of filters and membranes for use with most RO systems.
