The purest water from your tap
Reverse osmosis
A reverse osmosis system removes almost everything from the water that is not water. Whether it is worth it for you depends on your tap water, your consumption and your standards.
Technology
How a reverse osmosis system works: membrane, pressure, waste water
Reverse osmosis forces water through a membrane that lets almost only water molecules pass.
Costs
Is a reverse osmosis system worth it? Cost per litre calculated honestly
Purchase, filters, membrane, waste water, electricity: what a litre of reverse osmosis water really costs, compared with bottled water and tap water, and for whom the system pays off..
Minerals
Reverse osmosis water and minerals: empty, healthy, remineralised?
Reverse osmosis water is almost mineral-free.
Designs
