This system impresses with its robust construction and deliberately analog control – entirely without sensitive sensors or circuit boards. The open design makes maintenance easy: all components are accessible and replaceable. With proven technology, minimal power consumption (less than 0.1 watts in standby), and low operating costs for filters and spare parts, it is a well-designed and reliable solution for everyday use.

However, it's a system that requires some practice with reverse osmosis systems, for example, during installation and filter changes. If you're looking for a system that's as easy to use as possible, then take a look at the FlowOne+ or the Flow2.

The integrated pressure gauge ensures full control during filtration, displaying the current water pressure at all times. The manual flushing valve allows you to decide when and how often to flush – for effective and gentle membrane maintenance.

The system is modularly expandable: whether you need a post-filter, longer hoses, an additional tap, or a storage tank – it adapts flexibly to your requirements. And you also have a choice when it comes to performance: depending on your needs, the system is available in various performance levels from 200 to 750 GPD, thanks to the combination of membranes with different strengths.
