Reverse Osmosis FAQs

Is this system as effective as a traditional RO for filtering impurities?

Like other systems the USWF system provides greater than or equal to 95% TDS reduction*. Unlike traditional ROs, our tankless design and built-in pump enhance filtration, especially for those with low water pressure, eliminating tank back pressure on the RO membrane. *based on internal testing

How many filtration stages does this system have?

The system was designed for convenience and efficiency, featuring only 2 filter cartridges to facilitate effortless filter changes. However, within each cartridge, multiple layers of filtration work seamlessly, delivering a comprehensive 7-stage filtration process.

How much noise does the Tankless RO make?

When the RO's pump operates, it produces a sound level of 55-60dB. By comparison, appliances like dishwashers, washing machines, air conditioners, dehumidifiers, and sewing machines, generate between 60-65 dB. Because this system utilizes a pump when running, it is best that it is not touching the cabinet wall or any other items under your sink to reduce unnecessary vibration sounds.

Why does it make noise when I’m not using it?

The system performs an automatic flush cycle that lasts 60 seconds after the system has been idle for 5 minutes. The flush cycle rinses off the RO membrane to extend its life, and primes the RO with pure water so that your first cup is fresh every time.

Do I have to use the provided faucet with the system?

The system comes with a stainless steel LED faucet that displays color indicators for the system, but other faucets can be used in place of the provided faucet. You will still get the indicators on the faceplate of the system. If you wish to instead use another faucet with the system you absolutely can, you would just need one that connects to a 1/4 inch water line.

What is pure to drain water ratio?

Pure to drain water ratio is the amount of filtered water the system provides against the amount of water used to clean the system and is sent down the drain. Some conventional systems operate with a 1:4 pure to drain water ratio. While this ratio does an excellent job rinsing the membrane and prolonging its life, water is a precious resource and sending 4 or more gallons of water down the drain for only a single gallon used can feel excessive. The RO-2F-600 boasts an exceptional 2:1 pure to drain ratio meaning that it will only send 0.5 gallons of water to the drain for every gallon used, 8 times less than the amount of a conventional RO.





Quick Change Filters & Smart Filter Monitoring

Filters can be changed in just 3 seconds with a simple twist and pull. An integrated shutoff valve stops the flow of water as soon as a filter is removed so you won't have to crawl under the sink to turn off the water supply. The system monitors usage, and the LED smart faucet lights up to indicate when a filter change is required. The 1st cartridge lasts 1,000 gallons or 12 months, and the 2nd cartridge lasts 2,000 gallons or 24 months.



Smart Design & Easy Installation

The sleek, minimalist design measures only 5.5" W x 14.75" H x 17.3" D, taking up less than half the space of a system with a traditional water tank. Designed for easy, hassle-free installation, it comes with color-coded water lines, adaptable feed water supply which fits both 3/8" and 1/2" plumbing, and step-by-step DIY instructions so you can set the system up in 30 minutes or less.



High-Efficiency Performance & Less Water Waste

600 GPD & 2:1 Waste Ratio: Capable of producing 600 gallons per day, this system provides fast and robust water flow, which can fill a cup of water in just 9 seconds. The remarkably low 2:1 waste ratio means that for every 2 glasses of pure water, only 1 glass of wastewater is produced. This is 8 times less wastewater than traditional 1:4 undersink RO systems, saving you money on the water bill and protecting the environment's natural resources.

Next-Generation Features

The system includes an integrated internal waterway to eliminate seals and connections where leaks can occur. This system automatically flushes the RO membrane with filtered water after use, which not only greatly extends the life of the RO membrane but also prevents TDS creep. Flushing the membrane after each use ensures you get fresh filtered water in every glass.





Automatic Flushing

To extend membrane life and maintain a low drain ratio, the RO-2F-600 features an automatic flushing function. This flush, activated after 5 minutes of system inactivity, rinses away contaminants lingering on the membrane, thus prolonging its lifespan. Additionally, the flush replenishes the membrane with filtered water, preventing TDS creep—where contaminants can transfer from the untreated side to the filtered side during idle periods. This ensures the initial water dispensed after a period of inactivity remains consistently pure, eliminating the need for waiting periods before use and optimizing water quality.



Premium 7-Stage Filtration

Provides highly effective filtration with a 7-stage dual-cartridge design. The 4-stage CF cartridge is a composite pre-filter that removes sand, silt, rust, chlorine, VOCs, and improves taste. The 3-stage RO Membrane cartridge filters down to 0.0001 microns, which removes more than 1,000 impurities including TDS, PFAS, microplastics, fluoride, arsenic, nitrate, lead, and other heavy metals to provide clean, great-tasting drinking water.



Tankless Design

The high flow 600GPD membrane is capable of filling an 8oz glass in just 9 seconds, and you can use as much RO water as you'd like without running the tank down to a trickle. Removing the tank also eliminates the chore of cleaning the RO tank, and the risk of secondary contamination from an unsanitized tank.
The slim tankless design of the USWF Tankless RO System takes up 70% less space than a traditional RO system.
