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.

Installation
Installation
Installing your Classicos
The Classicos home RO system installs under a sink and connects to the cold water supply, the drain, the purified water faucet, and a 230 V electrical outlet needed to run the booster pump.
Place the pressurized tank close to the unit, in a position that gives easy access to its valve and the various connections.
The main connection steps
- Connecting the adapter to the cold water supply
- Connecting the feed water to the pre-filters
- Connecting the drain line to the drain saddle
- Connecting the pressurized tank
- Installing the purified water faucet
- Making the pump electrical connection
- Checking for leaks and starting up
Important: the RO system must be connected only to a cold drinking water supply. An accessible electrical outlet is also required to power the booster pump.
Practical tips
For a successful installation
Connections
Follow the connection direction shown in the manual and check that each tube is fully inserted into its quick-connect fitting.
Tubing routing
Make sure the tubing is neither pinched nor sharply bent, so water can flow properly.
Leak check
Once the system is pressurized, carefully check all fittings to confirm there are no leaks.
Start-up
Flush the filters and the membrane according to the manufacturer’s instructions before drinking the water produced.
Maintenance access
Leave enough space around the housings to make future replacement of consumables easier.

Maintenance
Maintenance and replacement of consumables
Regular maintenance is essential to keep water quality satisfactory and to protect the reverse osmosis membrane.
The Classicos has no automatic replacement reminder. Maintenance dates must therefore be tracked manually.
| Consumable | Function | Replacement |
| Pre-filter set | Protects the membrane from sediment and chlorine | According to Ecosoft recommendations and water quality |
| 50 GPD membrane | Main purification by reverse osmosis | Depending on water quality, usage, and observed performance |
| Carbon post-filter | Improves taste after the tank | According to the manufacturer’s recommendations |
| Remineralization cartridge | Adds calcium to the purified water | According to the manufacturer’s recommendations |
Good to know: replacement intervals should follow Ecosoft recommendations, the quality of your feed water, and how you use the system.
Limescale protection
Very hard water can reduce the performance and lifespan of the membrane. When the feed water is heavily loaded with limescale, suitable upstream treatment may be recommended.

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.
