Pure Blue
Three Stage Purification Process


1. Carbon and Sediment Filter
Removes sand, silt, sediment, chlorine and some organics such as pesticides and fertilizers.  This pre-filter serves to protect the reverse osmosis membrane from harmful contaminants.  Recommended filter replacement 6-12 month (depending on water quality).

2.  Reverse Osmosis Membrane
The heart of the system.  It is designed to filter water down to 0.00036 microns.  It removes 95% + of dissolved solids and dramatically reduces contaminants such as lead, sodium, nitrates, nitrites, chromium and barium.  Recommended membrane replacement every 3-5 years.

3.  Granular Activated Polishing Filter
A final polishing process which enhances the taste of your drinking water.  Recommended filter replacement every 6-12 months
