If your home’s water supply has high iron, manganese or hydrogen sulfide content, you should consider the addition of a whole house iron / hydrogen sulfide reduction filter to your water treatment system. This filter contains manganese greensand which reduces these contaminates through an oxidation / filtration process, thereby substantially improving water clarity, taste, and odor, while at the same time protecting your plumbing system including toilets, bath tubs and showers, and appliances such as clothes washers and dishwashers from unsightly staining.
It adds no harmful chemicals to the water, making it completely safe for drinking water applications. This filter should be installed on the inlet side of the home filter system.

Only for 3/4" connections.
