Stage 1 – Sediment filter.
The first stage of your RO system is a 10", 5 micron polypropylene sediment filter that traps bacteria, sediment and other suspended particulate matter like dirt, silt dust, mud, algae, and rust which affect the taste and appearance of your water, and cause reverse osmosis fouling.

Stage 3 – Granular Carbon filters.
The water then passes through 56 cubic inches of 10", 10 micron granulated activated carbon (GAC) filter to eliminate organic compounds, chlorine and other chemicals present in tap water that may otherwise alter the taste and color of your water supply.

Stage 3 – Block Carbon filters.
The third stage contains a 5 micron carbon block filter. This remove chlorine, bad tastes and odors, fungicides, pesticides volatile organic materials, (Cancer Causing) trihalomethanes , and other materials that cause bad taste and odor.

Stage 4- Membrane.
This stage is the heart of the reverse osmosis system; it uses a 0.0001 micron thin film composite membrane. This semi permeable membrane will effectively take out up to 99% of TDS-total dissolved solids, salts, heavy metals as arsenic, copper, nitrates, and lead, as well as bacteria & Cysts, as E .Coli , Giardia and cryptosporidium. Because the process of making this high quality drinking water takes time, your RO water treatment system is equipped with a storage tank.
 
Stage 5- Carbon inline filter.
The final stage is an inline coconut shell post carbon filter uses a granular activated coconut carbon impregnated with silver nitrates which design to kill bacteria come from the tank This filter is used after the water storage tank, and is used as a final polishing filter to Remove dissolved gasses, Absorb peculiar odors that may come from pressure tank, and enhance the clarity, and taste of your water.
