These things worth it? I was looking through the catalogue of a big highstreet store today and saw a few half decent ones going for under £30. I was bored and wanted to buy something pointless so it was either a breadmaker or a water filter 
Anyway, do they really make a difference? The one I was looking at came with a years worth of filters free too.

The one I'm after is a 1.5L jug that can fit in the fridge door as mentioned. How long does it take to filter the water once I've added it btw?
