  • Typical water treatment devices use mechanical filtration or chemical removal media.
  • Mechanical filters remove impurities from water by size exclusion method, where the pores in the filter prevents passage of particulates such as sediments. As a mechanical filter approaches the end of its useful life, particulate accumulation reduces or stops the flow of water completely; this change in flow rate of water through the filter provides an indication that the filter component replacement is necessary.
  • Chemical removal media e.g. charcoal-based media, ion exchange media

  • a disadvantage associated with using chemical removal media is that with usage the removal of impurities by the media decreases and eventually stops as the effective life of the chemical removal media ends, but unlike the mechanical filters, the chemical removal media does not provide any indication to the user that the chemical removal media therein is no longer effective.
  • various approaches to indicate end of life to the user when it is not inherently provided by the behaviour of the media have been taken.
