Tannin Filters

Is your rainwater discoloured throughout your house?


Tannin staining in rainwater is mostly caused by the water coming into contact with decaying leaves, gum nuts, gum flowers, and pollen that may have accumulated on the house roof or in the guttering. The rainwater absorbs the organic material and becomes yellow or brown stained, similar to making a pot of tea.


The tannins dissolve permanently into the water and won’t settle out over time. This can create a bad taste and odour in the water and cause staining to washing, toilet bowls, bath tubs and wash basins.

Our Solution to the Problem

The CA2 Carbon filtration system is specially designed for water clarification (colour removal), bacterial capture/retention, chlorine removal and odour/taste removal. The CA2 carbon filter system is installed following a Twin or Triple cartridge Whole House Water Filtration System which first removes sediment particles. The CA2 is an automatic filtration system which contains silver carbon media to absorb tannin from the rainwater supply. Silver is used to inhibit bacteria growth in the media. The system automatically back-washes itself on a weekly basis to remove impurities and ensure the carbon media is performing at it’s best to remove tannin from the rainwater supply.

Installation of the CA2 Carbon Tannin Removal system is very simple. It can be installed at the house or near the rainwater filtration system. It must be installed following a free-standing or wall-mounted rainwater filtration system. The twin filter system removes sediment particles prior to the carbon filtration process through pleated and poly spun filter cartridges.
