Nanofiltration (NF)  membrane

                                                         

PurePro Nanofiltration (NF) membranes are designed for the people who still want to keep the mineral elements inside their water. It is also the premier pre-filtration system available for water ionizers today. (EX: ERS-105-NF)  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.

PurePro is proud to introduce our newly designed residential membrane elements and our newly developed Nanofiltration (NF)  membrane:

 

 

 

Remark:
Membranes are made in U.S.A.

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.
