Our innovative double O-ring technology ensures that every drop of water is filtered.
Stage 1: Sediment Filter - removes larger particles such as dirt and rust. This pre-filtration stage significantly extends the life of subsequent filters and protects the entire system from clogging.
Stage 2: Carbon Block Filter - reduces chlorine and other chemicals. Its dense structure provides excellent filtration efficiency, effectively trapping a wide range of contaminants.
Stage 3: Sub-Micron Carbon Block Filter - Reduces chloramine, PFAS, and other chemicals through extended contact, maximizing the RO membrane's effectiveness in contaminant removal.
Stage 4: Reverse Osmosis Membrane - eliminates heavy metals, fluoride, and other dissolved solids. This semi-permeable membrane acts as a molecular sieve, allowing only water molecules to pass through while rejecting contaminants.
Stage 5: Post-Carbon Filter - enhances taste and removes any remaining impurities. This final polishing step ensures your water is not only pure but also delicious and refreshing.
Stage 6 (Optional): Alkaline Remineralization Filter - adds back healthy minerals for truly alkaline water. This unique stage balances the pH of your water, potentially offering additional health benefits and improved hydration.
This advanced in-line alkaline filter uses far-infrared technology to restructure water molecules for better absorption, while adding molecular hydrogen for antioxidant benefits. Experience premium hydration with easy 1/4" quick connect installation.

I couldn’t be more happy with
my new American Made 6 Stage RO system with US Water 20 inch high
flow whole house twin filter. For me, being made in America says
volumes about what a company is selling, it is difficult to find
products which are made in America these days.
I love that my new system came packaged so thoughtfully to prevent
damage during shipping. The operating and installation manual was
easy to follow, and made everything after that a pleasure...
Reverse osmosis (RO) is an advanced water purification process that uses a semi-permeable membrane to remove contaminants from water. Under pressure, water molecules pass through the membrane's tiny pores, while larger molecules like dissolved salts, bacteria, and other impurities are left behind. This results in highly purified water on one side and concentrated waste water on the other.
Reverse osmosis provides several key benefits: 1) Removes up to 99% of contaminants, including heavy metals, chlorine, and harmful microorganisms. 2) Improves taste and odor of water by eliminating chemicals and minerals that affect flavor. 3) Reduces the risk of waterborne diseases by removing bacteria and viruses. 4) Eliminates the need for bottled water, saving money and reducing plastic waste. 5) Provides clean, safe water for drinking, cooking, and other household uses.
While RO systems offer many benefits, there are a few considerations to keep in mind: 1) They can remove beneficial minerals along with contaminants, though our system's remineralization stage addresses this issue. 2) Traditional RO systems can waste water during the filtration process, though our efficient design minimizes this. 3) They require regular maintenance and filter replacements, but our system makes this process simple and infrequent. 4) Initial installation cost can be higher than basic filtration systems, but the long-term benefits and water quality improvements often outweigh this.
Reverse osmosis is highly effective at removing a wide range of contaminants, including: 1) Dissolved salts and minerals like sodium, chloride, copper, chromium, and lead. 2) Chemicals such as chlorine, fluoride, nitrates, and sulfates. 3) Microorganisms including bacteria, viruses, and protozoa. 4) Organic compounds like pesticides, herbicides, and pharmaceuticals. 5) Particulate matter such as rust, silt, and other suspended solids. Our American Made 6 Stage Alkaline Reverse Osmosis System goes even further by also removing PFOA/PFAS and thousands of other contaminants, providing you with the purest, safest water possible.

"It was packed well and the installation was done by a plumber who said the instructions were difficult because they were online. It works great, quiet and the water is good."
— Bradley V. (5/5)
"The water filter successfully filters water. 10/10 on the device itself. No notes. (Though I do wish the three pre-filters weren't a single unit, but that's hindsight) Now the service. Ordering replacement filters takes weeks. The online chat rarely works. The 'talk to an expert' email goes into a black hole and they don't reply. The phone service closes before the published hours on the website. Once you actually get a person, they're usually really helpful. But I get the feeling that the company is perpetually under-staffed to cut corners. I recommend buying your filters off Amazon (and I hate Amazon) because you can get them much faster. And if you're not quite handy and ready to support yourself, go with a local brand who you can ring up for service."
— L E. (2/5)
"Had some issues with understanding how the permeate pump is installed but there is a video that clears this up, also I called the help line. Having someone to ask questions and quickly get a hold of is great. Also had a leak at inline filters but they are quickly shipping another, all in all a great kit. love that this is made in the US"
— Christopher k. (5/5)
"I looked for a RO system that was made in the USA and did not come from a box store to ensure support and parts were available for years to come. I choose USA Water's stage 5 system and have been very happy with the outcome. I chose to place it in my basement's mechanical space so I ran a water line up to my refrigerator only for water and ice. I am getting 10 ppm water out of the system. Terry F."
— Terence F. (5/5)
"Really nice product. I am writing this review a year after I purchesd, installed and used this amazing RO filter. I also want to emphasize to buy American products like this one and you will not regret. I have combined this filter with a whole house bodyguard filter and water softener for my water condition and it is doing its job tremendously well. I do also want to mention that the costumer service is really helpful and professional. Keep up the hard work!"
— GERTI X. (5/5)
"Nice system, the feeder tank is large enough to run the icemaker on the fridge as well."
— Bob D. (5/5)
"Our American Made RO system hasn't been running for too long, but it installs easily, looks and feels well-built, and I appreciate it's US heritage! All components sent with the system appear high quality, and I can tell that thought was put into the contents of this kit. Even a tubing cutter was included. This system replaces a >20 year old system that came with our house and has served us well, but started springing leaks. I wasn't happy with the company that had been servicing it for us, so I decided I might as well replace the entire thing myself. I had to purchase a different fitting to splice into my water line, but that was due to the particular faucet connections I had available. I also needed some more line since this system wasn't going directly under the sink, but everything else needed was in the kit. The availability of an ice maker kit was another bonus. This may not be the cheapest option, but it definitely gives confidence that it will perform well for years to come. I highly recommend it."
— Matt M. (5/5)
"System is installed and running well. Water is clear and no longer cloudy coming directly out of faucet."
— Ben (5/5)
"I recently purchased the six stage RO system to replace my current system. I have a salt soft water system and my R/O water had tasted like salt. I read the reviews of the US Water Systems R/O system and purchased it. I instant it myself and man, I am blown away by the difference a high quality R/O system can make. My R/O water now tastes amazing. No BS, it tastes amazing. No salt flavor, and it has a nice crisp flavor that my entire family enjoys. I give it a 10 ☆ review."
— Ryan C. (5/5)
"I installed the unit in my basement under the kitchen and everything works great. The water tastes so smooth and good. Even my coffee tastes better."
— Fred C. (5/5)
