New Wave Enviro 10 Stage Plus Water Filter System and Cartridge

This filter is for New Wave Enviro 10 Stage Under Sink Water Filter System.

The 10 stages include:

  1. Stage 1 – 30-micron sponge filter which removes larger solids (sediments) such as rust.
  2.  Stage 2 – 8 oz. of KDF-55. KDF-55 is a patented alloy which removes free chlorine and some heavy metals, thereby prolonging the life of the filter and is an excellent Bacteriostat.
  3.  Stage 3 – 10 micron felt pad which traps smaller floating solids and separates the layers, preserving their integrity.
  4.  Stage 4 – 30 cubic inches of ultra-fine mesh, superior coconut shell, and granulated activated carbon. Granulated activated carbon has long been accepted by the E.P.A. and others as the premier, cost-effective way to remove chlorine, bad odors, and color from drinking water. G.A.C. also removes organic contaminants such as pesticides, herbicides, arsenic, mercury, and trihalomethanes – a cancer-causing organic pollutant.
  5.  Stage 5 – 10 micron felt pad for fine sediment removal.
  6.  Stage 6 – 7 cubic inches of ion exchange resin which removes lead to below minimum E.P.A. standards.
  7.  Stage 7 – An additional 30 micron felt pad provides an extra buffer against floating sediment of any kind.
  8.  Stage 8 – 7 cubic inch bed of G.A.C. which provides extra protection against cancer-causing organic pollutants.
  9.  Stage 9 – 2 oz. of calcite which raises the water’s pH and lowers acidity. It also increases alkalinity, which many nutritionists recommend.
  10.  Stage 10 – 1-micron absolute depth filter. A filter with a micron rating this small screens out cysts and protozoa, (including Giardia and Cryptosporidium), and gives the filtered water a sparkling clarity
