Are Carbon Water Filters Safe?

Carbon water filters can remove contaminants that are in your water supply and often improve the health and safety of drinking water. However, the efficacy of carbon water filters will depend on:

a) the kind of carbon filter (conventional or activated)

b) whether the filtration system has been certified

c) the regularity with which you replace your filters.

As experts in water filtration systems for over 25 years we’ve outlined below the key points you need to understand the question, ‘Are carbon water filters safe?’.

 

Is Carbon in Water Filters Dangerous?

There are two kinds of carbon water filters available:

  1. conventional carbon filters (made of granules) and;
  2. activated carbon filters (made of fibres).

 

Activated carbon filters are more effective because their multistage system increases the surface area available for filtration. Conventional carbon filters can be less effective because the resins which bond the granules reduce the filtration surface.

 

Is Carbon Filtered Water Safe?

Health certifications define the safety of each filter system. Billi’s premium activated carbon filters boast the Australian Standards WaterMark for product safety and consumer confidence to ensure you and your family have the highest level of drinking water available.

 

Are Carbon Water Filters Good and Are Carbon Water Filters Safe?

As noted above, activated carbon filters have more efficacy, and independent health certifications are central to the health of a system.

However, a carbon filter is only as good as its filter replacement and maintenance program. All filtered drinking water systems require these to ensure optimal quality and an ongoing high level of performance.
