The Vertex 4-Stage Reverse Osmosis water purifier uses advanced RO Membrane Technology to remove dissolved molecular contaminants from tap water. This is the same technology used by most bottled water companies.
Reverse Osmosis filtration purifies water by taking out the totally dissolved solids (TDS) which contaminate water. Although city water treatment removes the dirt and debris and adds chlorine to prevent the spread of diseases, it does not remove the dissolved solids from the water. And, with the increasing pollution of our surface and groundwater with contaminants, such as lead, mercury, and chromium-6, as well as the naturally occurring harmful contaminants such as arsenic, fluorides, and sulfides found in some areas of the country, it is more important than ever to have a way to remove these contaminants at the point of use.
4 Stages of Filtration in the PT-4.0 PureWaterMachine RO System
The PureWaterMachine PT4.0 Reverse Osmosis Drinking Water System comes complete, ready to install with instructions. The 4-stages are pre-assembled and tested. Long-reach chrome faucet, inlet water valve, drain saddle connection, storage tank valve, and color-coded plastic tubing for under-sink installation are all included.
- Stage 1 - Sediment Filter, 5-micron poly-spun cartridge - The 5-micron poly-spun filter takes out suspended solids such as dirt, rust, sand, and pipe scale.
- Stage 2 - Activated Carbon Block Filter, 10-micron - Activated carbon block filter removes chlorine, bad tastes, and odors.
- Stage 3 - Reverse Osmosis Membrane, 36 GPD - The heart of the Vertex PureWaterMachine is the reverse osmosis membrane. RO technology removes on average 95% of the dissolved solids in your water. Dissolved solids are not removed by municipal water treatment. This is why the Vertex PureWaterMachine RO System is an important safety factor for the water you drink and use in your cooking. City water pressure is used in the reverse osmosis membrane to force the water molecules through the membrane, but the larger contaminant molecules are kept behind and flushed to the sewer. The clean water goes into the storage tank and is held there ready for use. An auto-valve turns off the water when the tank is full. The tank is pressurized with a bladder which pushes the water out through the final filter.
- Stage 4 - Granular Activated Carbon post-filter - When the faucet is opened, clean water from the storage tank flows through the final polishing filter of activated carbon and into the faucet for your use. This special faucet is installed on your sink to dispense safe, good-tasting drinking water which is especially good for coffee, tea, and drinks.
- Optional Stage 4 GAC/Calcite filter - Brings the water pH back up to 7. Typically, reverse osmosis purification removes minerals which subsequently causes the pH level to drop. This optional post filter will replace the mineral and will raise the pH to (around) 7.
