Good quality

I have been using this brand for years even when I was not living in UK.

This is a very good ceramic filter with straightforward installation. Arrived perfectly sealed and I noticed that the water flavour has improved since adding this filter under the sink. I feel it is safer to drink water from the tap now and I have less limescale in the kettle. It seems durable and high quality, so I am very pleased to have tested this useful product.

Very good product, used it for many years, value for money.

*********************IMPORTANT NOTEDespite what some reviews have stated, this filter is NOT designed to be used in counter top gravity filter systems! For that you need the British Berkefeld Ultra Sterasyl (8674) with the black top. It is also made by Doulton, and it has a different thread to this one.*********************In my humble opinion, Doulton manufacture the best water filters available. They've been doing so here in Great Britain for other two hundred years. Modern Doulton filters make use of a super-fine microporous ceramic white outer, with carbon and other specialised filter media inside them.This gold topped Biotech Ultra filter candle is designed to screw into the new Doulton HIP range of under-counter filter housings (single, double and triple filter housing options are all available) They are intended for point-of-use filtration of drinking water, and they work to an extremely high standard. I use this system and the filters that come with it, and I highly recommend them, this filter included. Instead of being cloudy and tasting like a swimming pool, your drinking water becomes crystal clear and absolutely delicious. After a while, when your taste buds have recovered from being doused in chlorine, you will become aware of just how foul unfiltered tap water actually tastes in comparison.SPECIFICATIONHere are the specs, courtesy of Doulton:Width: 49 mmHeight: 248 mmThread M12Recommended replacement interval: 6 monthsFiltration capacity: 2300 litres (12.6 litres per day, ie enough drinking water for 6 adults)This filter will reduce the following in your drinking water:Turbidity,Pathogenic organisms (E.

The quality of the water filter is good however the packaging is bad without any protecting bubble wrap. It ends up one of the water filters is broken the big crack.

Product arrived in tact and passed testing however the shelf life of these is worrying at best, as they are just packed in bubble wrapping and within a carboard box...The industry standard for carbon filters for both air and water use is for the filter to be vaccume packed, outherwise exposure of ambient moisture and air contaminates degrades its useful life, and disqualifys it from medical setting use.
