We need to check whether you want an anti-scale cartidge
Normal carbon filters do not remove calcium - which is good for you, but causes scale
This may not be an issue as only some parts of the country have hard water ie scale.
Scale makes your kettle fur up with that hard whitish stuff,. And it can give your tea / coffee a dirty looking "skin" floating on the top. (Old water filter soldiers call this "scum". But that sounds too gross. It ain't that bad)
If, for any reason, you are unsatisfied with your purchase from UK Water Filters you can return it in its original condition within 90 days for a refund. We'll even pay for return postage costs. Read more.
