Zero Pure Plus (VOC) Reverse Osmosis Water Filtration System
Compact and powerful, this under-sink purifier removes harmful chemicals, heavy metals, and odors to provide fresh, clean water right from your kitchen tap.
Say goodbye to unpleasant tastes and odors with the Watts Premier RO Pure Plus Reverse Osmosis Filtration System, a complete filtration system designed to provide high-quality, great-tasting drinking water every time. This system includes an RO Pure Reverse Osmosis module with four pre-installed filters, a parts bag, a brushed nickel top mount air gap twist faucet, a 3-gallon storage tank, and an assembled ZeroWaste pump with solenoid and stand.
This kit includes one 5-Micron Sediment Filter (WP105311) for reducing dirt, silt, and rust that affects the taste and appearance of your water; one 5-Micron Activated Carbon Pre-Filter (WP105351) for reducing chlorine taste and odors; one VOC (Volatile Organic Compound) Filter (WP105381) for removing VOCs; one 50 GDP Membrane (WP105331) for reducing impurities like arsenic, lead, nitrates, percolate, copper, and dissolved solids.
Designed to fit comfortably under your sink, this system includes backflow prevention valves installed between the elements, as well as shutoff valves in each filter head and double O-rings in the cartridges to prevent leaks. Furthermore, filters are denoted by different colors for easy identification: red for sediment, yellow for pre-filter, silver for VOC, and green for membrane, and have a push button release that allows for hassle-free replacement without shutting off the water source.
To ensure proper operation, this system requires a 110V electrical outlet independent of the garbage disposal and a non-switched outlet for the pump. The system is not recommended for homes equipped with tankless water heaters or those with backflow prevention on the hot water heater. Additionally, it must be installed at least 25 pipe feet from the water heater to ensure optimal performance and prevent potential issues.

THE PREMIER DIFFERENCE: Since our founding in 1989, Premier has been dedicated to the design, development, and marketing of high-quality water filtration systems that exceed industry standards.

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.
The Zero Pure Plus Reverse Osmosis Filtration System uses a 4-Stage Filtration based upon separate treatments.
- Sediment : 5 Micron Sediment Filter traps sediment and other particles like dirt, silt and rust which affect the taste and appearance of your water.
- Carbon: 5 Micron Carbon Block Filter reducing Chlorine, and other materials that cause bad taste and odor.
- 50 GP Membrane: Semipermeable Membrane removes TDS, Sodium and a wide range of contaminants such as Chromium, Arsenic, Copper, and Lead.
- VOC (Volatile Organic Chemical): 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.
