Filtration Process

Two-stage filtration process

Our Doulton Stainless Steel Twin Undersink system features a highly effective two stage filtration process.

Stage 1Doulton Sterasyl 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.
Stage 2Doulton Superblock Carbon 1 Micron Post-filter

The Doulton Twin Undersink combines Ultra-fine ceramic technology in the first stage with a premium one micron carbon block filter manufactured in the USA. The one 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.

With the Doulton Stainless Steel Twin Undersink Filter your family will be guaranteed micro-biologically safe drinking water.

The Doulton Sterasyl and Ultracarb cartridges are Made in UK

Included within the purchase of this system is your choice of a designer, premium faucet.
