"Absolutely outstanding service. These folks really do know how to do an amazing job. I honestly am so delighted with everything they have done. The kit is superb, water tastes wonderful. They always send the filters quickly and have answered many questions I had when fitting the system and the replacement filters. I highly recommend them. Such lovely staff, always so helpful and easy to contact when you need advice. So very glad I went with them and so grateful to them for such a high quality service. 🤩 great work 🤩"

Product Description
Get your filtered water delivered via your existing kitchen sink cold water tap - instead of having the usual extra small tap that is required with most undersink water filters.
This amazing filter contains powerful Granular Activated Carbon to give you very high quality filtered water.
The filter sits out of sight, under your sink, and is quickly and easily placed "in-line" on your cold water pipe.
It greatly improves the taste of your water by removing virtually all chlorine and many other chemicals that affect the taste and quality of your drinking water.
Not only do you get a simple practical solution for your filtered water needs but the special carbon filtration media also gives you the sweetest tasting water possible.
What it Removes
Chlorine - up to 99%
Organic contaminants - up to 99%
VOCs - up to 99%
Other impurities - up to 99%
It also removes other contaminants - such as trihalomethanes (THM), pesticides, industrial solvents (halogenated hydrocarbons), polychlorinated biphenyls (PCBs), and polycyclic aromatic hydrocarbons (PAHs). (See full chart below)
New, fully approved technology
The filter works by using fully proven Granular Activated Carbon.
It is Made in the USA.
* Your Anti-Scale Solution Option
Buy this filter with a powerful Scalemaster Anti Scale Electrolytic Gold to help solve your drinking water / scale issues. It will also protect all the equipment in your house forever. You only need to buy it once - no replacement parts required. Fit and forget.
How long does the filter last for?
The filter needs to be changed every 6 months.
What happens when it's time to Renew?
You simply buy a new one and replace it for the old one. You can claim a £5 discount as a loyalty bonus. (Sorry it can't be more but these are high quality filters that cost us a lot to make).
Fitting your new Filter
You need to cut your cold water copper pipe and place the filter into the gap - so that it sits "in-line".
This is a job that can be done fairly quickly by a DIY enthusiast - a pipe cutter will be needed - or it is a very simple job for a plumber.
When it comes to changing the filter - every 6 months - you will be able to quickly remove the filter by manipulating the easy push fit fittings at either end.
(This should be easy. But to be sure you can do it, get your plumber to show you how - and try it yourself - before they leave).
Includes free bracket clip (usual price £4.95) to secure your new filter to the wall.
Secures filter firmly while allowing for easy push on pull off
Very quick, one screw assembly
More on Fitting and Replacements
Simple to fit (15mm push fit ends).
The filter can fit in line into your copper or plastic flexible water supply pipe.
Plumber or advanced DIY required for FIRST fitting only.
Replacement filters can be fitted by yourself. This will take 2 minutes max.
Filter lasts for 6 months before replacement.
We send you free reminders when it is time to change.
The filter replaces itself, i.e. you take out the old one and replace it for an identical filter.

Fitting your new filter to flexi hose pipe connection
To connect the Keep Your Existing Tap filter to flexi hose with female connections you will just need 2 x 3/8" to 15mm compression fitting adapters to screw into your flexi hose with female connections and two pieces of 15mm copper / plastic pipe to fit into the filter either end. About 70mm of pipe is needed for either end then just reconnect to the flexible pipe compression fittings.

Such an improvement over unfiltered water. Losing microplastics, scale, chlorine and all the other nasties that can work their way in is just a bit of piece of mind for me in relation to my kids.
– Nick Love
I've had the filter installed for 1 month now and the water tastes loads better and no more smell of chemicals, just clean fresh filtered water I'd say it's the best water I've ever had.
– Neil Bradfield
“My filter fits easy and I am happy. We weigh the old filter when it is removed, filled with gunge which never got into our bodies with this filter. It’s quite frightening. My filter is worth every penny!
