If space is at a premium in your kitchen as it is in ours, and you are often short of time when preparing your coffee, your might want to acquire one of these; a kettle with a built in water filter.  One less item on the bench, one less water transfer.  3000W heating a single litre of water helps it get the job done in a hurry.  Probably lacking sufficient capacity for a large family, but adequate for one, two, or three people. 

The second image in the series is a close up of the ubiquitous 'time-driven' Brita profit engine ;) telling the health obsessive to change the filter every 4 weeks, even if its only had 5 litres through it!  We'd show a little more respect if this indicator was 'volume' driven, but as an accountant in a former life I can't see that happening any time soon.

Bottom image: Ah well, nothing's perfect.  Nasty neon blue light appears when you switch it on.

Remember that filtering your water doesn't just significantly improve the taste of your coffee (much greater clarity in the taste, not dissimilar to the clarity that hi-fi brings to audio), but reduces staining in the cups which I find a benefit of almost equal value.

I understand from the Brita literature that the Maxtra is a 4-stage filter, removing something like 20% more impurities than their standard filter.  As always, remember that filters only work until the filter is saturated with pollutants.  If you keep using a filter beyond this point it just lets the pollutants pass on through.

As mentioned above, I have a bit of a problem with the time driven indicator that Brita provide, as time is a constant, whereas I suspect many of their customers never put anything like the rated volume of water that the filter is designed to process before the 4 weeks is up and the indicator suggests a new filter is due.  Selling fear? Surely not.

Notwithstanding, a great product.

We acquired ours from Sainsbury's, I'm sure they're available from numerous retailers and online.
