The Omnipure Q5586 Under-Sink Drinking Water Filter System not the cheapest but it is great!. Far, far better that a cheap one I had previously!!…Being in a hard water area, I hated the taste of my tap water. But after fitting the filter, the result is an instant improvement that makes the water taste like bottled water! And, I love it as will save money and the environment. I understand however that the filter will not remove lime scale so, if that’s what you’re after, then this product it probably not for you,. But, If you want great tasting clean and clear water?… then this filter will be right up your street. I had a slight issue in that a 1/4” push fit adapter; to fit on the water faucet was not included which was slightly disappointing , but filter flair customer service were great and recommended the products I needed to purchase, in order to remedy the problem.; this was a two part push fit adapter, that cost an extra £10, (ordered from filter flair too.) I received it the very next day of ordering. All in all I would highly recommend the filter and the filter flair company, who's costumer service was second to none. The products arrived very quickly too which was very much appreciated
