No more difficult laboring under the sink! The most user friendly under counter water filter yet!

Doulton has produced some of the most powerful and reliable systems on the market since 1927 and the commitment to improve the products is always a top priority. Listening to the consumers, we have certainly been able to better gauge which products present the most opportunity for improvement and in what areas. A traditional under sink filter has always presented the possibility of being over-tightened, therefore, difficult to reopen from under sink. This new design will resolve the difficulties of cleaning or changing out the filter.

Exclusive Doulton's silver/ceramic technology reduces >99.99% of particles 0.2 micron and larger in size including pathogenic bacteria such as E.coli, salmonella etc.

Reduces dirt, chlorine taste and odor, mold, algae and removes 100% Cryptosporidium and Giardia cysts.

An economical alternative to bottled water, reverse osmosis, distillation and ultra-violet technologies.
