Q:What
contaminants does Reverse Osmosis Remove ?�
The PPW*
System contains a quality carbon filter which will remove more than 98%
of organic chemicals from the water. These include THMs(chloroform), DBCP,
lindane, TCEs(trichloroethylene), PCEs(tetrachloroethylene), carbon tetrachloride
chlorine, In addition to these organic chemicals, below is a partial list
of other contaminants removed by the Desal* TFC membrane. The percentage
of removal shown below is a conservative estimate.�

Q:How does Reverse Osmosis differ from a Water Filter?
A: Ordinary water filters use a screen to separate only particles of dirt sediment from water. Reverse osmosis employs a semipermeable membrane that removes not only particles but also an extremely high percentage of dissolved contaminants-molecule by molecule- from raw tap water.
Q:Don't people need minerals removed from the water?
A: Most of the minerals that we receive are from the foods we eat. Only a very small percentage comes from the water we drink.
