Our Iron Removal Filters are an easy-to-use solution to treat dissolved iron, they work by oxidising iron to form particulate which is then held in the filter matrix and as such removed from the water. Iron is commonly found in private water supplies and in corroded pipework, which can cause a number of complications including staining and poor tasting drinking water. These filters are designed to fit inside a standard 20″ large diameter (4.5″ diameter) filter housing, which enables it to be installed at the point of entry to a property and sit inline with existing pipework.

It is recommended to use our Iron Removal Filters as part of a 3 stage system consisting of:

  1. 5 Micron Sediment Filter
  2. Iron Removal Filter
  3. Carbon Filter

By using these filters in the 3 stage cascade above you can maximise the lifespan of the filter by protecting it from particulate build up. The carbon filter improves results further, polishing any remaining colour, taste and odour from the water which ensures it is desirable for drinking.

How Often Do I Need To Change These Iron Removal Filters?
This depends on the concentration of iron in your water supply, the higher the iron concentration the shorter the lifespan of the filter. Below is a guide as to what you can expect at different concentrations of iron:

At 1ppm iron the average lifespan is 300,000L (Approximately 320 days of use in a home with 4 occupants)
At 2ppm iron the average lifespan is 150,000L (Approximately 160 days of use in a home with 4 occupants)
At 3ppm iron the average lifespan is 98,000L (Approximately 104 days of use in a home with 4 occupants)
