The Zero Pure Plus Reverse Osmosis Filtration System combines the space saving, compact design of the RO Pure Plus and the water conservation of a ZeroWaste® Unit. Our patented design wastes no water where other Reverse Osmosis Systems waste as much as 4 or more gallons for every 1 gallon of drinking water produced. Whereas this Reverse Osmosis System does not waste water by returning the unused waste water from the system back to the home’s hot water supply. Changing the filters is as easy as pushing a button! With the built in shut off valve when removing the filters there is no mess like traditional models. The filters snap out and are easily inserted.

The Zero Pure Plus Reverse Osmosis System uses a VOC (Volatile Organic Chemical) Filtration. It is estimated that VOC's are present in 1/5th of the nation's water supplies. These water contaminants can enter ground water from a variety of sources including localized use of herbicides and pesticides, gasoline or oil spills, leaking underground fuel tanks, septic system cleaners, and chemicals used in the dry-cleaning industry.
**This system is NOT available for purchase in California**

The Zero Pure Plus Reverse Osmosis Filtration System uses a 4-Stage Filtration based upon separate treatments.

    • Sediment - A 5 Micron Sediment Filter traps sediment and other particles like dirt, silt and rust which affect the taste and appearance of your water.

    • Carbon - A 5 Micron Carbon Block Filter reducing Chlorine, Chloramines and other materials that cause bad taste and odor.

    • 50 GP Membrane - A Semipermeable Membrane removes TDS, Sodium and a wide range of contaminants such as Chromium, Arsenic, Copper, Lead as well as Cysts, such as Giardia and Cryptosporidium.

    • VOC (Volatile Organic Chemical)- A high quality VOC Final Polishing Filter after the water storage tank to remove MTBE's, Atraine, Benene, Chloroform, Lindane and other VOC's from your drinking water.
