The 4-Layer Earth Replacement Filter fits in the bottom tank of the Auro 5-Stage Water Filtration System. It contains four stages of activated carbon, zeolites, silica sand, and ion exchange resin are highly effective in the removal of bad odors, tastes, and other compounds.

Activated Carbon
Carbon has been used since ancient times (1200 BC) to purify water. Activated carbon is â€Å“activatedâ€Â by heat and oxygen to create a high surface area which absorbs a wide range of contaminants frequently found in water.

Zeolites
Zeolites are micro-porous, aluminosilicate minerals with a unique cage-like structure that makes them useful in many ways, especially in water filters. Their ion-exchange and absorption properties are used to reduce odor and clean heavy metals and other natural compounds from water.

Silica Sand
Silica sand is commonly used in water filters because of its highly absorbent qualities to remove granular contaminants, suspended solids and colloids.

Ion Exchange Resin
In water purification, ion exchange resin is used to remove poisonous and heavy metal ions, replacing them with more harmless ions, such as sodium or potassium.

Features:

  • Long-lasting â€â€œ Replace once every 6 months.
  • Provides 500 gallons of clean, great-tasting water.
  • Easy to insert & replace.
  • No maintenance required.
