Description of Pur Water Filter

STAGE 1:  (SED; 5 Micron Sedimentary Filter)
Sediment Removal / PP– Commercial grade sediment filter. Sediment filtration extracts suspended sediment, dirt, rust, silt and sand ranging from filtration of 20 microns down to 5 microns. Reduces particles 8 times smaller than what the naked eye can see.

STAGE 2:  (GAC; 5 Micron Granular Activated Carbon for Chemicals)
Granulated Activated Carbon /UDF - High efficiency pre-filter reduces and removes: chlorine, volatile organic compounds (V.O.C), pesticides, nitrates, herbicides, tastes, odor, and disinfection by products (Chloramines, THM, TCE). Cartridges are constructed totally of FDA grade materials and media. In addition KDF media may be used for the removal of lead and other heavy metals.
 
STAGE 3:  (CCB; 1 Micron Coconut Carbon Block for Chemicals)
Carbon Block Filter / CTO – High efficiency pre-filter removes Chlorine, then reduces or removes Pesticides, Nitrates, Herbicides, tastes, odor, and disinfection by-products (chloramines, THM, TCE), Volatile Organic Compounds (V.O.C).

STAGE 4:  (100 GPD Reverse Osmosis Membrane)
Reverse Osmosis Membrane- This semi permeable membrane filters and rejects tiny impurities, colloid, heavy metal, dissolvable solids, germs and other harmful substances. Virtually only water molecules and dissolved oxygen can pass through the membrane.  The rejected contaminants are flushed to drain. The product water is essentially nothing but high quality, low TDS water.

STAGE 5:  (Demineralization by Ionization DI Resin Bead Filtration)
Resin Filter / Demineralization by Ionization– Removes hard water minerals through an ion exchange process. Intended to prevent inorganic calcium, magnesium, and soluble iron etc...  Greatly increases quality of filtration.

STAGE6:  (PC; Post Carbon polishing filters for taste and odor)
Post Activated Carbon Filter / T33- This carbon filter treats only R.O. water so it does an excellent job of "polishing" any Volatile Organic Compounds (V.O.C), Pesticides, Nitrates, Herbicides, tastes, odor, and disinfection by-products (chloramines, THM, TCE). That may have slipped through the membrane, plus, adsorbs any odors that may come from the pressure storage tank. Gives water a clean refreshed taste on the way to your tap.
