Having a reverse osmosis system at home means having access to perfectly pure drinking water. This highly popular triple-filtration device provides water free of chemicals and pollutants. Josmose.fr specializes in this field and offers a wide range of RO systems with different capacities and uses. In addition to the good results and optimal efficiency for which Josmose.fr selects its products, we also pay close attention to the quality and appearance of our RO systems. A stylish RO system is a key selection criterion.
The RO system with a faucet
An RO system can be a tank-based RO system or a direct-flow RO system. The first stores water after filtration, while the second gives you direct access to purified water through a faucet. The 80 L direct-flow RO system is a model that provides direct flow at a high water flow rate. Its design features smart lighting.
The Robustos Café RO system is a stylish, compact model that provides direct access to crystal-clear water for making coffee. The Optimos RO system has a discreet color scheme and orange filter cartridges. With its direct-flow mechanism, its compact format gives the device a stable base.
The RO water dispenser
You can have pure water at your table or in an office. An RO water dispenser is designed to be portable and positioned according to your needs and preferences. The Limpidos is a portable 75 GPD RO water dispenser, a small model that provides cold or hot water simply by connecting it to an electrical supply. This 75 GPD RO system requires no special installation and is very easy to maintain. With an original, understated black-and-white design, this RO system is powerful enough to provide a cold or hot drink.
Other models also include the Compactos ultra-compact RO system with a pump, with or without a tank which, in addition to being practical, has a pristine white housing, a hygienic color perfectly suited to its 5 filtration stages. With this design, this RO system can fit at the end of your backsplash or along the side of a countertop. The water it produces is certified pure, free of pollutants and chemical particles.
What are the advantages and disadvantages of an RO system?
RO systems, particularly these models, stand out for their ability to provide healthy drinking water instantly. They are the best alternative to packs of bottled water piling up at home. The main benefit of RO water is its purity and unaltered taste. These devices remain good investments, since you can choose an affordable model that delivers good results.
Made from high-quality materials, durable and stylish, the RO systems offered on josmose.fr have been thoroughly inspected. Their compact design also ensures better technical support during the filtration process. The price of an RO system is another key criterion: an RO system should have a cost that reflects its performance.
