Doulton twin under sink alkaliser

Doulton twin under sink alkaliser


Neat and compact, the Royal Doulton Superblock Twin under sink water filter system can be conveniently installed under the sink and comes with your choice of attractive, designer chrome taps, at no extra charge. The taps can be easily mounted on your stainless steel sink, or corona or granite bench-top.


The additional Alkahydrate filter cartridge is the latest premium, alkaliser filter available. Providing you with enhanced water that is alkaline, re-mineralised, energised, has low ORP and one of the best absorption rates possible.


3-Stage filtration process

Stage 1 - Doulton ceramic 0.9 micron absolute pre-filter
The first stage filter cartridge in the Twin Undersink System has two important functions:

Mechanically filters out harmful bacteria and parasites as well as dirt, rust and sediment.
Removing the above contaminants protects the Carbon Block cartridge allowing it to function more effectively and last longer.
Stage 2 - Carbon block 1 micron post filter
The Doulton Twin Undersink combines Ultra-fine ceramic technology with a premium one micron carbon block filter manufactured in 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.

Stage 3 - Alkahydrate alkaliser filter
The Alkahydrate alkaliser filter effectively raises pH levels as well as producing antioxidant and oxygenating qualities. The filter also emits far-infrared rays which result in shorter cluster chains in the water molecules - increasing the bio-available response and oxygen absorption in the body.

With the Royal Doulton Superblock Twin Undersink with Alkaliser Filter your family will be guaranteed micro-biologically safe drinking water with the additional health benefits derived from alkaline water pH.


The Doulton Ceramic Superblock Undersink is self maintainable. If the flow rate slows, the Doulton Sterasyl ceramic cartridge can be cleaned easily with a quality scrubing pad such as Scotch Brite™ under running water. Cleaning frequency will vary depending upon water quality.

The Royal Doulton Ultracarb Ceramic Cartridge has been tested and certified by the Hong Kong Standards and Testing Centre (No: HC109730) and the National Sanitation Foundation (NSF53).
