*Note :- Heavy Metal reduction is for a very short period only, often only a couple of hundred litres (this is an industry standard for premium carbon block cartridges & those with a small resin core). For effective long term, year round Heavy Metal reduction our Reverse Osmosis purifier filters down to a molecular level at 0.0005 microns (1,000 times finer than most water filters), well below the size of all Heavy Metals thus ensuring excellent long term reduction.

**Chloroform, a Trihalomethane – is a Carcinogen (a substance capable of causing Cancer) formed in water when Chlorine, added as a disinfectant, reacts with natural organic matter from decayed vegetation. Both our Triple undersink water filter & Reverse Osmosis purifier effectively remove Chloroform.

*Fluoride Reverse Osmosis is the safest, most efficient method of removing Fluoride however some water filters companies use filter cartridges containing Aluminium or Ion Exchage Resin:

  • Aluminium Oxide or Activated Alumina cartridges - we strongly recommend that you do not use Aluminium to remove Fluoride as Aluminium has been linked to Alzheimer’s disease. We do not sell or use this cartridge.
  • Ion Exchange Resin - anion resin cartridge with negatively charged ions on the resin surface that exchange with negatively charged ions in the water. Removes some contaminants including nitrate, fluoride, sulfate, and arsenic until the capacity of the resin has exhausted. As Fluoride is tasteless, there is no indication that the resin has exhausted and stopped working. Many ion exchange systems have only a token amount of resin in them & work for only a couple of months. So you never know when it is no longer removing Fluoride!
  • Reverse osmosis membranes removes ALL contaminents including Fluoride by simply filtering down below the size of them  -  very safe and effective. It does not leave any harmful cross contamination like Aluminium nor exhausts and stops working like Ion Exchange Resin. You can easily test if the Reverse Osmosis membrace is still working by doing a TDS test (total dissolved solids) on your water sample & as the membrane fails after many years it can be easily replaced. Reverse Omsosis is the safest and most thorough method of removing ALL contaminents from your drinking water - very similar to rain water where there is no air pollution.
