How can I reduce sodium (salt), copper, or nitrates in my water?

 
 
Reverse Osmosis Systems reduce sodium (salt), copper, and nitrates. The membrane in Reverse Osmosis Systems reduces these total dissolved solids. Regular drinking water and sediment filter cartridges are not able to reduce dissolved solids. Filter cartridges are able to reduce suspended solids down to very low micron levels but cannot reduce dissolved solids.

How do I reduce iron in my water?

 
 
A three stage process helps to reduce iron in water.

Stage 1: Use a Sediment Prefilter to reduce sediment in your water. The DGD-5005-20 is a dual-gradient sediment filter with an outer layer that filters down to 50 microns and an inner layer that filters down to 5 microns.

Stage 2: Use the iron reduction water filter RFFE20-BB to Oxidize the iron. The RFFE20-BB water filter reduces iron in concentrations of up to 3 parts per million. For higher concentrations of iron, a larger iron system will be needed.

Stage 3: Use the RFC-20BB water filter to filter the partially oxidized iron and improve taste and odor.

How do I reduce the sulfur smell in my water?

 
 
This is a very common problem for private wells. The smell of sulfur is difficult to remove from water. The best solution are bladderless pressure tanks with aerator valves. Taste and odor carbon filters will reduce the smell, but they will need changing frequently. The reason for the frequent changes is that the sulfur smell will return once the oxygen in the filter cartridge is exhausted. A more robust solution is to get an aerator that will continually provide oxygen that will combine with other elements in your water. The resulting chemical reactions remove the sulfur smell.
