Stage 1 - Doulton Ceramic 0.2 (Nominal) Micron Pre Filter

Doulton Ceramic Filters have provided microbiologically safe drinking water around the world for over 100 years. As the first stage filter cartridge in the Twin Under sink System, the Doulton Sterasyl Ceramic Filter Cartridge has two important functions:

1. Mechanically filters out harmful bacteria and parasites such as Ecoli, Giardia and Cryptosporidium 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.

Scour-Clean Cartridge:

If the flow rate slows, the Doulton Sterasyl ceramic cartridge can be cleaned easily with a quality scrubbing pad such as Scotch Brite™ under running water. Cleaning frequency will vary depending upon water quality.

Stage 2 - Carbon Block 1 Micron Post Filter

The Doulton Twin Under sink combines Ultra-fine ceramic technology with a premium one micron carbon block filter manufactured in USA. The one micron carbon block filter effectively removes 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 Royal Doulton Superblock Twin Under sink Filter your family will be guaranteed micro-biologically safe drinking water. The exceptional performance of the Royal Doulton Sterasyl Ceramic Cartridge has been tested and certified.

I decided on this system mainly because of the washable ceramic pre-filter. A 0.2 um system which removes everything from bacteria on up, that can simply be scrubbed off and re-used once it gets clogged, at a comparable price to single-use 0.5 or 1 um filters. What\'s not to like? The system looks robust, and simple to put together (we haven\'t done so yet, since we\'ll be installing it in our new house). The tap (the only bit that will be visible once it\'s installed) appears solid, stylish and well made - incidentally, our order came with a different tap to the one we ordered, but one email later a replacement was in the mail and arrived two days later, no questions asked. That\'s what I call good service!

Excellent system easy to install. Ceramic filter needs to be cleaned every 2 months but that seems to be because of the sediment in our area. Overall great product.

Great on tank waterI use this system to filter my tank water which seems to be working well considering some of the things i have found in it

Great system easy to install...
Went into the Pymble store to purchase a new filter for my fridge and decided to ask the question - is there anyway to install a under sink system to the fridge? the reasoning for this was cheaper replacements. The advice that was given to me was excellent, the installation videos made the install a breeze and the overall experience was great. Water tastes good and don't need to worry about replacing the filters so often.

Pain if you have..
Hard or high sediment water need to clean the ceramic every couple of weeks where i live. At least i know its doing its job. Apart from that it would be 5 stars
