The Rainwater Filter System Comprises Of 3 Stages:

  1. 90 Micron Stainless Steel Mesh Filter: Featuring spring assembly and drain in base for easy cleaning without removal. Ideal for removing large debris like leaves and dirt.
  2. 25 Micron Wound Sediment Filter: Offering finer filtration down to 25 micron, removing silt, dirt and fine sediment. Also the recommended level of filtration prior to a UV system.
  3. Carbon Block Filter: Removes organics, solvents, herbicides and other contaminants, whilst tackling unpleasant colours and odours that may be in the water.

How Often Do I Need To Change The Filters In The Rainwater Filter System?
It is recommended to clean the mesh filter when visibly dirty, using the built-in spring to clean the filter without removing it. If extremely fouled, the mesh filter should be removed from the housing and cleaned thoroughly. The wound sediment filter and carbon filter should be changed every 6-12 months depending on use.
