Group Brown Filter Bag - The NEW Millbank Bag!
The Brown Filter Bag just got BIGGER…
Now endorsed by SAS Legend ‘Lofty’ Wiseman, the launch of the Brown Filter Bag was a huge success and so, as with the old MOD Patrol Milbank bag we are glad to bring you a larger ‘Group Brown Bag’ ideal for larger groups, expeditions, Scout camps, disaster aid or for your Base Camp.
"Making water safe to drink from an unknown source is a two way process. First by filtering, second by treatment with a modern purification unit, or, by chemicals or boiling. Filtering removes all the suspended matter from the water extending the life of a purification unit, or allowing the chemicals used to be more effective. A Millbank bag is perfect for this and was standard issue to our regiment in the Far East, where 90 % of all ailments were water related. The resurrection of the original Millbank bag, to the same spec and using the same fabric makes The Brown Filter Bag a great asset to anyone interested in the outdoors or survival and preparedness!”

The Millbank bag pre-filters turbid water removing any organic material and sediment. Today, even with the advances in modern purification systems the Millbank bag is a necessity. You will have heard the adage that you should always start with water that is as clean as possible, but most if not all of the systems available today to purify water have just a basic sponge pre-filter.
Turbid water is water with sediment suspended in it, so if the water that you have access to is muddy or cloudy you could have matter such as decomposing organic materials, sand, mud or silt in it. These alone can upset the balance in your digestive system, but more importantly are known to reduce the effectiveness of chemical purification as sediment and organic matter hinder effective chemical treatment. Such water is also know to clog purification systems, increasing maintenance and reducing life expectancy. Pre-treating water reduces wear and tear on purification systems.
Simon Ellar, editor of Bushcraft & Survival Skills magazine said “Millbank bags are an invaluable tool when it comes to processing ‘dirty’ water to drink. They are particularly useful in sandy and dusty regions. When I was in the Sahara I witnessed a number of leading brand purification systems fail. This was due to the amount of sediment in the water from our well, made worse by a series of sand storms. Pre-filtering the water through a Millbank bag and careful selection of a purification system meant that for over a week I had and was able to assist others with filtered, purified water to drink – a necessity in the desert!”
These bags are made from fabric woven to exactly the same spec as the MOD canvas, by the original fabric company; producing a new filter bag that performs as well as the original. The advantage of the new bags is that the canvas is a more subtle brown colour and also the canvas meets the current MOD specification with regards to toxic treatments and coatings. The earlier Millbank bags had a Cuprammonium (CA) chemical treatment that is not used on the new canvas as it may be hazardous. The end result is a proven, high quality product, 100% UK made.
The bags do what they say, they filter out large particulate matter and are not designed to remove bacteria or parasite eggs (Cryptosporidium). However, some fluorescent beads were used in the testing which are slightly larger than bacteria, mimicking parasite eggs and these were decreased by two thirds in number by filtration. So whilst all water passed through the bags should be boiled, chemically treated or passed through a water purification system, it is good to know that they are already assisting and taking the pressure off the next step.

HOW DO YOU USE IT?
- Soak the bag thoroughly by squeezing it under water
- Fill the bag to the top with ‘dirty’ water
- Hang the bag up and allow water to run as waste until the water reaches the fill
- Place a collecting vessel under the bag to collect the pre- filtered water Boil the collected water or use a chemical treatment or purification system to purify it
- Raise your glass and say cheers!
