Why Countertop Reverse Osmosis Makes Sense
Many customers want the performance of reverse osmosis but do not want under sink installation, extra drilling or a separate filtered water tap. The Osmio Zero 3.0 solves that problem by bringing RO filtration, hydrogen rich water, chilled water and hot water into one countertop appliance. It is a strong choice for renters, kitchens where plumbing changes are difficult, or households that want a flexible drinking water system that can move with them.
The Osmio Zero 3.0 Hydrogen Reverse Osmosis System combines RO purification, SPE electrolysis for hydrogen rich water, rare earth thick film heating and chilled dispensing in one compact unit. The system uses a removable tank at the back, which means there is no under sink plumbing, no permanent pipework change and no separate tap installation.
The system comes with filters pre installed, making it straightforward to get started once the initial setup and flushing process has been completed according to the user manual.
