First post so be nice :)
Found this and looks like it has not been posted before.
they have other models also at half price.
Description from their website
The IX250 range of water filters have a multi-stage filtration system built into a single cartridge which restores the natural taste of water and makes tea, coffee and cordials more appetising.
Most people realise their tap water contains chemicals which have been added during water treatment or have leached from other polluting sources. These can give water an unpleasant taste and/or odour and may give rise to health concerns.
