Slim Reverse Osmosis Water Filtration Systems with a Tank

About R.O. Filtration

Reverse osmosis is currently the most advanced yet natural method of water purification. Semipermeable membrane allows only water to pass through and rejects everything else.

R.O. treated water is free from chlorine, heavy metals, other dissolved solids and ions, bacteria and viruses. This water is safe and refreshing, requires no boiling and is a good choice for all kind of use including newborn baby feeding.

Make no mistake, this osmosis process is as much natural as it can be since it’s essentially the same as the one in every living cell on Earth. Cell membrane allows only what it needs to get through and rejects everything foreign.

These days the human genius reproduced this natural process in a highly sophisticated nanotechnology device right at your sink.

No magic, no unproven claims – just pure science! Reverse osmosis is used everywhere when real clean water is needed, not claims: from pharmaceutical production to space station water supply, from multi-million population area municipal water desalination plants to marine ship rescue kits.
