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.

"Haven't had that strong chlorine smell since the system is installed. Also plants seem to be growing better. Water is drinkable and don't have to use additional filter any longer."
— Jayne M. (5/5)
"I have had this installed for about 6 months now and connected it to a faucet as well as my ice maker. I sometimes use a gallon of RO water at a time and the system never runs out of water and the pressure doesn't drop off hardly at all. Overall great system, no complaints."
— Ryan (5/5)
"Fleck 9100 twin tank water softener with 6 stage American Made water filtration and new whole house sediment filter. Running off well water. Install was completed by me (homeowner) with little to no trouble. CSR team and Tech team were outstanding for answering a lot of questions before the purchase and after for installation. Everyone professional and very knowledgeable. We lived with hard water for about a year not realizing how bad it got. It ruined our fixtures. We did not know what we were missing until the install was completed and soft water was running again. . . . super soft! Amazing results from dishwasher to laundry. Pricing and quality stand out for a system that is easy to install with some mechanical and plumbing knowledge. Don't think about doing it. . . . . do it today! Your water quality and life will be better for it. Thanks Jim"
— Jim (5/5)
"Good instructions and it is great how many particules it filters out. We live near big farm fields so it is nice to have something that will filter out the nitrates! I have been very pleased with the results of the 4 stage product and how long it is lasting."
— Gregory (5/5)
"We really appreciate the elaborate water analysis and installed systems at our current and future houses to help our well water. I'm one of those old guys that needs simple printed instructions like IKEA and found the QR code an inconvenience; especially without cell service. I was not sure I added the three modules to the correct canisters and it was not easy to identify specific filter module colors and locations. A couple of decals on the device would really help. It's working now and we'll dump the first two tanks. I found a spare "cartridge" labeled as a membrane but nothing mentioned installation location. It has push in couplings at each end for the smaller plastic tubes. I was not able to locate a mineralizing module to restore flavor to the purified water. We'll have good drinking water much less of our trace arsenic. The device is working great. Better printed instructions with simple sketches would be very helpful."
— Frederick (4/5)
"I recently purchased an under-the-sink reverse osmosis system from US Water. The system was easy to install, it’s well-built, and my water tastes amazing. Do yourself a favor and pick one up for clean water at the tap."
— Adam M. (5/5)
"Dumps gallons of water non stop. custo. er service can't fix it changed both valves multiple times ran all kinds of tests. Had to call outside expert for house call,not free,and he can't understand what's wrong. Junk, 0 stars."
— neil (1/5)
"Was an easy install, just make sure that you plan it out before hand and have all the fittings you will need especially if you are going to add your refrigerator to it. The pressure is so much better than the cheap Chinese make that I had before this one. Would recommend to anyone looking for a good RO system. I can also recommend the water test as well. Thanks US Water!"
— John M. (5/5)
"The system is awesome. The quality and taste of the water is exactly what we were looking for. I would highly recommend US Water Systems."
— Peter W. (5/5)
"6 months and it just works, no issues, no drama. Installation was easy but needs attention to detail if you care to keep your house dry."
— Richard (5/5)
