Changing Your Cartridge

 *Lasts up to 12 months in 95% of UK Water Areas

Depending on local water chemistry.

Please note that it's hard for us to be certain this filter will stop scale in your drinking water for a full year. This is because there are thousands of local water treatment plants in the UK. Each has a unique water chemistry - which can change regularly. However rest assured that the cartridges do work well for a full 12 months for 95% plus of our customers.

Even if you're in a particularly bad area the filter should last for 9 months plus. What can make a big difference is the flow rate of water going through the filter. The slower the better. You might need to reduce to 2 litres a minute. (This will fill your kettle for a cup of tea in a few seconds).

To adjust the flow rate simply use a flow restrictor / shut off valve

If you don't already have one ask us and we'll send one for free with your new filter. (Usual price £6.97).

We guarantee the filter will remove scale for nine months. If it doesn't send it back and we will refund you on a pro-rata basis - click here for more details

What Type of Plastic is this Housing Made From?

These housing units are made of PolyPropylene (PP).

If you're concerned about plastics - we think you're right to be.

Plastics like BPA's (often found in food and water containers) and Phthalates (in PVC products etc) are linked to cancers, fertility problems, obesity, hormone / endocrine disruption and God knows what else. 

The problem is they leach into the food or liquid they're holding.

However PolyPropolene (ie our housings) does not contain BPA's or Phthalates. and is thought to be much safer because it doesn't leach chemicals like some other plastics do.

PolyPropolene is one of the oldest and most commonly plastics with no known negative health effects after seventy years in widespread use (Sources: ESIS – European Chemical Substances Information - and the Hazardous Substance Data Bank (USA).

Ratings & reviews

Good value for money - Review by Tracy Archdale
The item I ordered was delivered within a few days. The filter was easy to install and the quality of the tap water has now notably improved. I think the filter I purchased was very good value for money.
Easy To Fit - Review by Colin Taylor
Decent looking device, easy to fit and l.ooking forward to having a limescale free kettle
Great product, reasonably priced - Review by Peter Doyle
Installed this product in the new bar at our hotel. Very popular with our customers because they know we use the purified water to make our ice cubes for their drinks.
It is a wonderful product, very reasonably priced and fits very neatly under the sink.
This system is great - Review by Simon Young
This system is great - we never imagined it was possible to have such pure tasting water.
Also no scale in the kettle unlike bottled water.
The installation instructions are comprehensive and clear and our plumber was able to install it easily within an hour, and the results exceeded our expectations.
Highly recommended
This review was also placed on MyLocalServices the independent review site.

easy to fit - Review by John
I fitted the water dispenser yesterday at our facility and wanted to give you some feedback when fitted. Works very well.
very pleased - Review by Mrs Sheridan
Thank you for checking in on my order.
Yes the new water filter arrived. I will be replacing the old filter at the end of the month and expect the new filter to be as good as ever; I have been buying filters from you for a few years now and have always been pleased.
I can't fault the service - Review by Les Dean
I ordered an under worktop drinking water filter unit with an anti scale filter, this arrived promptly on time.

The water through this unit at first tasted bitter, but after talking to UK water filters I have turned the flow rate down which although now takes a little longer to fill up the kettle or glass of water has greatly improved the taste.

I can't fault the service I've received and will probably buy another for my son's house.
Very happy - Review by Barry
Very pleased with quality of this filter, good strong metal brackets. Very easy to install. UK-water-filters are excellent to deal with, their customer service is the best I have ever come across from the point of ordering to follow up email to make sure I was happy with everything. Water taste great.
More about customer service than product - Review by Rotherham Girl
I can't actually say as yet how good the product is because it has only been installed for a couple of days. What I can say is that the customer service is excellent. I needed extra connections to fit the system to existing tap and pipework and upon enquiring I was sent connections for free with no postage. Service doesn't get better than that.
very impressed - Review by Adrian
The water filter arrived and the only word to describe the change to the quality of the water is amazing.

Before if we made a cup of of tea not only could we smell the chlorine but also taste it. Also the bottom of the cup had a film on the dregs after the tea had been drunk - not pleasant.

When tea is now being made as the water hits the tea we can smell tea and not chemicals.

Orange squash tastes of oranges.

It took 30 mins to install and the results were instantaneous.

We are very impressed with the filter.
just what we needed - Review by Lee
Thanks for the email the water filters are superb one is in spain replacing a 5 stage osmosis which broke and a bit excessive for drinking water the second will be fitted to house in england within a month
Happy - Review by Tom
Very pleased. It removes the scale so there is no film on the surface of the tea and water tastes great
Thank you - Review by Michelle
Lovely filter. Really happy with it. Thank you for the great service. Will recommend you to all our friends and family
recommend you without hesitation - Review by Steve
Thank you for you prompt and excellent service. The filter arrived within days of ordering ... if only more online companies took your care and concern.

Brilliant!, I shall recommend you without hesitation. Mr S Smith
