Rated 3 out of 5 by Poor Pipe fitting not as illustrated on web page, the web page shows a wrap a round fitting , water flow only gives a maximum of 1/2 litre per minute. This was installed by a professional plumber. 16 Jun 2016
Rated 5 out of 5 by Great diy filter kit We have tried several water filters over the years. This is not the cheapest, but definitely the best we have had. The kit is easy to fit and replacement filters are readily available, need to replace after 6-9 months as water flow slows. 11 May 2016
Rated 4 out of 5 by Water Filter Kit This replaces one that started leaking, but it was over 12years old. Only gripe filters are a bit pricey. 26 Apr 2016
Rated 5 out of 5 by Exceptional We have been using this tap all day, every day for the past 3 years. It's brilliant. We are now buying another. The filters are very special and remove the horrid 'chlorine' taste of our tap water and make it taste of nothing - which is what we want! The filters seem to last for about 6 months, then the taste starts to change back to 'chlorine'. So go ahead and buy it - you'll be really pleased. Does not remove much limescale - but that gives you Calcium in your diet for good bone growth - so why would you want to remove it! 4 Apr 2016

Answer: 
Unfortunately the High Performance Filter Kit does not reduce lime scale in the water supply, it is a taste and odour removal kit and it has a fine 0.5 micron particulate filter rating to remove impurities such as Cysts,Lead,Lindane, Atrazine and Turbidity any of which may or may not be present in the water supply.
For lime scale reduction we would recommend the BWT Water Filter Kit Screwfix part number 14306.

Answer: 
I am a retired water scientist, not a medic, but I would avoid any device that purports to calcium and magnesium that occur naturally in chalk derived water as these are essential elements for things like bone structure.
A water softener removes calcium and replaces it with sodium, hence the salt regeneration requirement and an ion exchange resin.
Soft water is great for everything except drinking, and can be a health hazard.
The filter cartridge is the key part of all this.
It can filter solids (a sediment filter) and possibly some larger bacteria and microorganisms, but that's all.
An activated carbon filter is aimed at mainly organic compounds, some of which cause odour, but should not be in a public water supply.
Chlorine disinfects drinking water and if removed, renders the water non-sterile. Boiling or letting it stand is more effective for removing than a filter.
The answer by the BWT expert is curious in that by saying that their filter removes lindane ( a long banned organochlorine pesticide) and atrazine, suggests that the filter has an activated carbon element, then goes on to say that it removes lead (long since taken out of water supply pipework) which would suggest that it is also a resin based filter, so would remove calcium?
My advice would be to get a sediment and activated carbon filter, see the "furred" kettle as an indication of healthy water and avoid resin filters.
I would challenge the BWT expert to provide evidence that water company provided potable water has any level of lead in it that remotely comes close to requiring removal. You can request a lead analysis if you are concerned. Or for lindane as well.
Some of these claims are misleading and out of date
