SWT MetalsMaster™ Reverse Osmosis Systems are especially designed for areas with water supplies contaminated by heavy metals and high TDS. They combine RO technology with oxidation/carbon filtration to bring up to 36 gallons per day of bottled water quality to the faucet at a fraction of the cost. That's 36 gallons of clear, refreshing water that is not only healthy to drink, but good for cooking and for use in appliances such as steam irons, humidifiers, ice makers, and car batteries.

• Convenient 3 position faucet
• Large water reservoir
• All hardware necessary for installation

• The first stage contains a 5 micron sediment cartridge that removes silt sand, sludge, and grit from the water supply.
• The second stage is a specially designed carbon block that has been blended with an oxidation media which traps particulates of metals such as lead and copper. This block also removes, or greatly reduces, most of the chemical compounds that the EPA has deemed as health hazards in drinking water (see list below). As compared to systems not having this type of prefilter, this stage greatly extends the life of the RO membrane when treating high TDS water.
• The third stage hyperfiltrates the water under pressure and forces it through a reverse osmosis membrane which treats the prefiltered water on a molecular level, filtering out 93% to 98% of dissolved solids such as salt, nitrates, lead, fluoride, and arsenic. It also filters out organisms such as cryptosporidium and giardia cysts.
• The water then enters a storage tank until needed.
• The final stage is a second carbon filter which is used to polish the RO water just prior to the faucet.

With proper installation and maintenance the RO membrane module in the SWT Metals Master™ Reverse Osmosis System will reject the following substances from tap water:
