Under Sink Reverse Osmosis Water Filter 

Under Sink Reverse Osmosis Water Filter Systems remove undesirable materials from water by using pressure to force the water molecules through a semipermeable membrane. This process is called “reverse” osmosis because the pressure forces the water to flow in the reverse direction (from the concentrated solution to the dilute solution) to the flow direction (from the dilute to the concentrated) in the process of natural osmosis. Visit ‘How Does Reverse Osmosis Work‘ guide to learn more and see the steps in a reverse osmosis system.

Reverse osmosis water filtration systems can remove 90% of total dissolved solids (TDS) from water and can provide the purest water available for your home. Reverse osmosis water filters remove a wide range of contaminants and minerals from your drinking water, including sand, chlorine, fluoride, cryptosporidium, and hexavalent chromium.

What is Reverse Osmosis?
Reverse osmosis (RO) is a membrane-technology filtration method that removes many types of large molecules and ions from solutions by applying pressure to the solution when it is on one side of a selective membrane. The result is that the solute is retained on the pressurized side of the membrane and the pure solvent is allowed to pass to the other side.

Reverse osmosis is most commonly known for its use in drinking water purification from seawater, removing the salt and other substances from the water molecules.

Stages in Reverse Osmosis

1. Sediment Pre-Filter

Melt Blown Polypropylene removes dirt, rust and sediment particles down to 5 microns. There are several different types of sediment cartridges.

2. Carbon Pre-Filter

Coconut Shell Carbon Block Cartridge(s), 10 Micron removes chlorine, taste, odor and chemical contaminants.

3. Reverse Osmosis Membrane

Thin Film Composite (TFC) rejects (removes) 95% of Total Dissolved Solids (TDS) down to .0001 Microns.

4. Post Carbon Filter

Coconut Shell Activated Carbon is the final polishing filter after storage tank, just before you use the water.
