Oestrogen

Both our Standard and Heavy Metal Filters contain Carbon which has been proven to be effective at removing Oestrogen from water. There is, however, still some debate over its efficacy. For example, a peer reviewed academic article, published in ‘Environmental Processes’ journal, has tested the efficacy of Carbon in the removing of Oestrogens and found that it is indeed effective1. This is in contrast to the pop Science magazine, Scientific American, which states that the efficacy of Carbon is still yet to be proven2. The latter article argues instead that Reverse Osmosis should be employed for the removal of oestrogen but do not cite any research to support this notion.

The article published in Environmental Processes (by Jens Hartmann) concludes that activated carbon is one of “the most promising adsorbents for the removal of estrogen [sic]”. While Powdered Carbon may provide the best adsorption kinetics the practicability of using this form of Carbon inside a water filter mean that a coarser Carbon must be used.
