Adding the optional Berkey PF-4 Fluoride Filters

The Berkey PF-4 Fluoride and Arsenic reduction elements are designed for use with the 7 Inch Long Mount Doulton Super Sterasyl™ and the Doulton ATC Super Sterasyl™ ceramic filtration elements which are used in the Doulton SS Gravity Water Filter Systems.

The PF-4 filters adsorb the following four unwanted elements most commonly found in drinking water.


- MTBE (Methyl-tertiary-butyl-ether)
- Fluoride
- Lead
- Arsenic

PF-4™ filters are also designed to adsorb:

- DBCP (Dibromo-chloro-propane)
- THMs (trihalomethanes)
- Herbicides & Pesticides
- Heavy Metal ions

Simply add these to your order. The PF-4 Filters are fitted in the lower chamber of the Gravity system (not the upper chamber), so they will reduce the lower chamber water holding capacity slightly.

SKU Doulton SS Gravity Water Filter
Brand Doulton
Filter Parameter No
In Depth For customers who do not have a reliable pressurised mains water supply, whether it is at home, on a campsite, or in a holiday
cottage, a gravity filter enables you to have clean filtered drinking water on tap. Water is poured manually into the upper chamber. It
passes through the filter candles under pressure of gravity into the lower chamber where the filtered water can be accessed via a
tap on the front of the filter.

Made from high grade polished stainless steel, the SS Gravity
Filter is a portable, robust model, which is easy to keep hygienically clean.
The SS is very popular with aid organisations and private customers alike.

"A recent study by a leading UK University showed that use of British Berkefeld® drinking water filters in a community in Zimbabwe slashed cases of potentially fatal diarrhoea (a common problem in Africa caused by pathogenic bacteria and cysts in the water supply) to virtually zero. British Berkefeld® filters have been shown to work in the most demanding conditions.

All portable systems are fitted with genuine Doulton candles®. Wing nut and gasket are included with every replacement element.

Container Capacity: 10 Litres or 3 US Gallons.
Typical Output per day: 40 Litres or 10 US Gallons.
Empty Weight: 2.5 kg or 5.5 lbs.

Used by many of the world's leading relief organizations including US Military.

The SS is fitted with 2 candles.
When fitted with Sterasyl™ filter candles, the output of the SS, assuming regular refilling of the upper chamber, will be approximately as follows:

2 candles – 11 US gallons (40 litres) per 24 hours

Dimensions: Assembled 8" x 19" / Stored 8" x 13.5"
Upper Reservoir Holds 8 liters of Untreated Water
Lower Reservoir Holds 8 liters of Treated Water

All SS filters have four holes to enable the fitting of up to 2 candles.

As standard, the SS takes candles which are 7 inches long, 2 inches in diameter, with a long mount and a wing nut. The SS should be fitted with either Sterasyl™ or Super Sterasyl™

For ease of transport, the upper chamber fits into the lower chamber to save space.
  1. Excellent filters review by Steve Liddle on 11/05/2016

    I have used camping filters in the past, but wanted something a bit more substantial and this one whilst not cheap is a lot better.
    Had to flush it out a couple of times, but then have noticed a fresh flavour to the water, makes me want to drink plain water where as before, I had to add squash to the water to mask the flavour of the chlorine.

    Went for the sight glass spigot to give me an idea of the volume and use an old 5 litre plastic container to top up the pre filter, takes a lot of the guesswork out and would be a pain to have to lift the lid all the time to determine the volume.

    Black Berkey Water Filter Elements (Set of 2) BB9-2
    Berkey PF-2 Fluoride & Arsenic Filters (2 pack)PF-2
    7.5" Sight Glass Spigot Travel &Big System SG-7.5

    Guess the main reason for buying the filter is that I have biofilm issues in the water, which could be removed with chlorine injection into the mains supply, but that is not guaranteed to get rid of it

    It is supposed to be portable, but decided against that, it sits on top of the fridge to give me enough height and space under the tap :)

  2. Excellent System review by Phil on 31/01/2016

    I have only had my British Berkefeld for approx two weeks.In this short time ,I can confidently say it is everything I had hoped for.The price ,the quality and ease of use is brilliant.The taste of my water is sweet and delicious.It far outweighs the distiller I have,both in water quality and running costs.Many thanks Osmio,from a very satisfied and hydrated customer.

  3. good review by l barker on 19/04/2014

    good value

  4. Overall very good review by NickO on 12/11/2013

    The only niggle is that because of the curvature of the case, the flat washers don't seal easily. Had to silicone it up to stop leaking. Could you do a longer tap?
    The water tastes great and I am really pleased.

  5. WOW! review by palmer on 01/11/2013

    Wow!!! ive done ALOT of research about this product and MANY others including propur ( very similar to this product, only difference I could find was the size of the filters and the price.. everything else i.e quality was the same) Also BERKY another favourite, but this is massively expensive( just because you may have enough quids to throw away it doesn't mean you have to) and thus was not an option for me. Being frugal and still desireing the best quality I researched and THANK THE LORD I found this. Unlike some other brands this one has a hard top/lid. Able to contain 2.25LT of water its basically the same as ''A BIG BERKY''. Altough I have done my research I was still a lil sceptical as to the ''real difference'' in the water..WELL!?? WOW! WOW! WOW!!! The water where I am has a heavy smell of chlorine, but I was more concerned with the bactereor,cysts protozoers etc not to mention the fluoride. First let me say the price of this item is UNMATCHED! I couldn't find a cheap price like this anywhere,inclu of USA websites. The quality of this item is SUPER! The only thing I would have preferred is a stainless steal tap instead of the hardcore plastic, but nevertheless its still hardwearing. This thing is so simple to set up.The WATER DOES TASTE DIFFERENT!! Not like any water ive tasted..its actually sweet tasting(no more swimming pool water for us) MY kids even drink more water due to the fact that it makes them feel ''posh'' (ya know like those water butts in offices) As far as the fluoride is concerned I intend on purchasing fluoride filters from Berky as im pretty sure that they'll fit in the lower chamber on the supplied filters...just need to experiment. Next got to think about a shower filter..so far its looking like the vit C shower head for us. oh also, the British Berkfield portable and great for bug-outers and campers alike as it filters even stagnant water..lake,pond, etc so GREAT in a ''cut off'' situation.
