The Doulton Ceramic Twin Undersink system is one of our most popular systems for residential filtration with it’s effective two stage filtration process within neat and compact design.

Stage 1Doulton Ceramic 0.2 micron Pre-filter

The first stage filter cartridge in the Twin Undersink System has two important functions:

  1. Mechanically filters out harmful bacteria and parasites as well as dirt, rust and sediment.
  2. Removing the above contaminants protects the Carbon Block cartridge allowing it to function more effectively and last longer.

The second stage features a premium 1 micron carbon block filter, manufactured in the USA. The 1 micron carbon block filter effectively removes all chlorine, chemicals, pesticides, unpleasant tastes and odour along with harmful heavy metals. Made from premium coconut-shell carbon, fresher, sweeter tasting water is ensured.
