Having decided to get a gravity fed water filter we set about researching options. Originally a different brand was being considered before we came across Doulton. Instantly we were impressed by their transparency as a company. Having then purchased a 6 liter system with a stainless tap we could not be more pleased with it. You get a British made sustainable ceramic filter system with the peace of mind from NSF testing. Once accustomed to the flow rate there is something therapeutic about the water dripping slowly through the filter. The ceramic candles are relatively biodegradable and offer quality beautiful tasting clean water that is plentiful. Highly recommend as the first choice for your water filtration.
