Finally, a tank-based RO system Made in Europe! Discover the PURE BALANCE MINI RO system
- AquaSpring system : calcium & magnesium remineralization
- Eco-friendly : produces only 1 liter of wastewater for each liter of RO water (at a pressure of 3 to 6 bar)
- Sturdy & durable : BWT group
- Works WITHOUT electricity!
Note: This is the version of the Pure Balance without a pump. The 1:1 recovery ratio only applies at pressures of 3 bar or higher. Below that, the unit produces more wastewater (approximately 2.5 liters to produce 1 liter at 2 bar). The model with a booster pump is available here if your pressure is too low.

Certifications
Certifications
Quality accreditations for our RO systems
RoHS
Restriction of Hazardous Substances
The RoHS directive regulates the use of certain hazardous substances in electrical and electronic equipment to limit their presence in the components concerned.
CE marking
European conformity
CE marking indicates that the product concerned meets the applicable European requirements allowing it to be placed on the market within the European Economic Area.
FDA
U.S. Food and Drug Administration
The FDA is the U.S. authority responsible, among other things, for regulating many products related to food, health, and consumer safety.
Water Quality
Water treatment industry
This accreditation is associated with the water treatment and filtration industry and helps identify products that meet the relevant standards.
ISO 9001 & ISO 14001
Quality and environmental management
The ISO 9001 standard covers quality management systems, while the ISO 14001 standard addresses environmental management.
NSF
Standards related to water and public health safety
NSF develops, among other things, standards and evaluation protocols applicable to equipment and components used in water treatment.
Water quality and NSF certification
Understanding certification standards and the assurances associated with reverse osmosis membranes.
Are your RO systems NSF certified?
A reverse osmosis membrane referenced in Josmose documentation, the RHD3013-600, holds NSF/ANSI 58 certification covering the safety of its materials. This certification does not mean that all Josmose RO systems are NSF certified. The scope of certification must always be checked for the model and components concerned.
What exactly does NSF 58 certification guarantee?
The NSF/ANSI 58 standard covers, among other things, material safety and certain characteristics of reverse osmosis systems. For the RHD3013-600 membrane, the test documents indicate an analysis covering more than 150 substances, including solvents, phthalates, nitrosamines, and hydrocarbons. No exceedances of the applicable thresholds were found. Please note: this material certification does not validate the contaminant reduction rates of the complete RO system.
What is the difference between NSF 58 and NSF 61?
The NSF/ANSI 58 standard covers home reverse osmosis water treatment systems. The NSF/ANSI 61 standard primarily addresses materials and components in drinking water distribution installations, such as pipes and valves. The two standards serve different purposes and rely on appropriate safety criteria.
How can you verify NSF certification?
Visit the official NSF website and consult the drinking water treatment equipment database. Search for the manufacturer Ningbo RXHL Technology and model RHD3013-600. Check that the certificate matches the component used in your unit and review the characteristics actually covered.
Where are the RO systems and their membranes manufactured?
Josmose technical documentation indicates that they are manufactured in China. The manufacturer of the RHD3013-600 membrane, Ningbo RXHL Technology, is monitored by NSF as part of its certification. Manufacturing origin alone is not enough to determine the quality of an RO system: materials, checks performed, and traceability are also essential.
Do you have test results for the filtered water?
Independent testing of the units is listed as ongoing in our documentation. A TDS tester also lets you measure the total amount of dissolved solids in the water before and after filtration. This measurement provides an indication of how reverse osmosis is working, but cannot, on its own, verify the absence of PFAS, pesticides, or other specific contaminants.

Reverse Osmosis
Benefits of reverse osmosis
High-precision filtration for everyday water
A reverse osmosis system uses the principle of reverse osmosis to reduce many dissolved substances and impurities present in water. This technology produces highly purified water, available directly at the faucet or water dispenser.
Why choose reverse osmosis?
The main benefits
- High-precision filtration: reverse osmosis reduces a wide range of substances present in water.
- Micropollutant reduction: the membrane acts as an especially fine barrier against many dissolved contaminants.
- Better taste and odor: filtration helps reduce chlorine in particular, along with compounds that can affect the organoleptic qualities of water.
- Fewer bottles: having filtered water at home or at work reduces the buying, storing and carrying of bottles.
- Reduced mineral content: reverse osmosis greatly reduces dissolved mineral salts, including those responsible for limescale buildup.
- Less plastic waste: a great way to cut down on single-use bottles.
Reverse osmosis or ultrafiltration? Discover the differences between reverse osmosis and ultrafiltration .
What can reverse osmosis reduce?
Examples of substances and impurities
Depending on the membrane used, the quality of the feed water and the operating conditions, reverse osmosis can help reduce many substances present in water.
Heavy metals Lead Mercury Nitrates Pesticides Dissolved salts Chlorine Fluorides Pharmaceutical residues Micropollutants PFAS
