Here's a kitchen mixer that I have just ordered for my client's kitchen. It is a Triflow tap - which mean it has hot, cold and filtered water all in one. This a great solution as there aren't many nice looking water filter taps out there. It also keeps the area around the sink clean and minimal - this is ideal when the sink is located in the kitchen's central island in the middle of an open plan kitchen, dining and living area.
