Nanofiltration (NF) Membrane - For Mineral Water !!

PurePro RO systems (with NF membrane) are designed for the people who still want to keep mineral elements inside their water. This is also the premier pre-filtration system available for water ionizers today. The size of the pores on the NF membrane are 0.0008 microns allowing it to remove bacteria, viruses, heavy metals, viral contaminants, and other dangerous elements while still allowing valuable minerals through for the water ionizer to ionize, and your body to absorb.

The nanofiltration pore size diagram below will help you more understand the relative pore sizes of Membranes and the sizes of the common impurities.

 

 

 

The Nanofiltration pore size at 0.0008 microns, is only slightly larger than the RO pore (0.0001 microns) and also only very slightly larger than the size of the common salt (NaCl) molecule. So it allows monovalent common salt sodium chloride to pass through but will not allow divalent calcium salts like calcium carbonate of dia 0.0009 microns to pass through. Nanofiltration and Reverse Osmosis RO membranes remove Mercury, Lead, Heavy Metals, Arsenic, all germs and viruses from water and makes hard water soft.

ERS-105-NF can be installed with any brand water ionizer (with water ionizer faucet!)

 

Quick-change cartridge filters ** Quick-Change RO systems are so easy to service !!
The newly designed quick-change RO system (with NF membrane) is user friendly with design simplicity in mind. It requires no tools for filter changes. Use twist and quick-change cartridge design makes filter changes fast, clean and easy. This space saving allows maximum use of your under counter space.

 

 

          

Quick change RO systems significantly reduce filter change time!
Change filters with a single 1/4 turn twist! Much quicker than traditional systems!

(Stage 1) 5 Micron Sediment Filter :
With only five micron rating. It is effective in removing dirt, rust and sand particles.
(Stage 2) Granular Activated Carbon Filter:
It takes out 99% of the chlorine and organic chemicals. It provides enhanced reduction of taste, odor, and color.
(Stage 3) Granular Activated Carbon Filter :
It takes out 99% of the chlorine and organic chemicals. It provides enhanced reduction of taste, odor, and color.
(Stage 4) Nanofiltration Membrane:
A thin film composite (TFC) high quality membrane that processes 100 gallons per day. It remove the following hard water contaminants that may be present in your water: lead, cooper, barium, chromium, mercury, sodium, cadmium, fluoride, nitrite, nitrate, and selenium.  (PurePro USA Catalogues.)  ( PurePro USA NF Membrane Catalogs-1   Catalogs-2   Catalogs-3 )
(Stage 5) Alkaline Plus Filter:
The Alkaline filter changes the acidic RO water into a perfect Natural Alkali Calcium Ionized Water. The Alkaline filter simply gives back minerals such as ionized calcium, magnesium, sodium, potassium ion, which were taken away while purifying the water.

Water, water everywhere…and lots of dangerous plastic bottles everywhere.
Worldwide, people are buying billions of dollars of water in plastic bottles. When the cost of that bottled water is calculated taking into consideration the price of producing the water, the energy required for manufacturing, the oil needed to make the plastic bottles and the green-house gasses emitted during production and transportation…the cost of that water - the dangerous effects of plastic to our bodies and our planet - is much greater than you think.
