Water in its Purest Sense

Nelsen reverse-osmosis drinking water systems significantly reduce unwanted substances bigger than 0.0001” such as carcinogens, heavy metal ions such as cadmium, chromium, lead and mercury; chlorine, cryptosporidium, salts, turbidity, nitrate, VOC’s, organic compounds, dissolved solids, tastes and odors leaving only clean, great tasting water.

How does the Process Work

Reverse osmosis is the same process used by most major bottled water suppliers. With a Nelsen Reverse Osmosis Drinking Water System, you can have the same high-quality water available from your own faucet for a fraction of the cost of bottled water.

Just how does the reverse osmosis process work? During the process, water is forced through a semi-permeable membrane that traps contaminants. These contaminants are then flushed out of the system and down the drain, leaving your drinking water clean and fresh.

PRE-FILTER (Carbon Block)

RO MEMBRANE

Thin Film Composite design. Rejects 98% of the dissolved metals and salts, plus other harmful contaminants.

POST-FILTER (Carbon Block) 

Removes any remaining objectional tastes and odors picked up in the storage tank.
