What is this water filter bag designed to do?

Making water safe is a two stage process:

1. Filtration
2. Purification

The Brown Filter Bag can be used for the first stage of making water safe, filtration. It is designed to filter turbid or dirty water. Turbid water is water with suspended sediment in it such as sand, mud, silt or organic matter.

It is essential to remove the sediment as it provides hiding places for water borne pathogens i.e. viruses, bacteria and parasites. If the sediment is not removed this is known to reduce the effectiveness of chemical purification treatments on these pathogens. In addition, if the sediment is not removed it can upset your digestive system a great deal. 

What are the advantages of the Brown Filter Bag?

It is compact, lightweight, very durable, virtually unbreakable and it has an unlimited filtering capacity. Due to its compact size and lightness it can be easily stored and carried in your everyday essential kit.

Using your water filter bag for the first time:

Prior to using your brand new Brown Filter Bag on your next trip, expedition or adventure it is essential that the new bag is broken in before. The fibers and weave of the canvas need to be loosened up and opened in order to maximize its performance. Simply give your new bag a hand wash with warm water prior to its first use. That's it!

How to break in your new water filter bag:

1. Saturate the bags in water, squeeze the water through the bags to ensure they are fully wetted.

2. Then be rough with them! Scrunch them up, massage and squeeze the bags. This will help to soften the canvas and open up the fibers.

3. Repeat the process 3-4 times allowing the bag to dry in-between.

4. You can also put the bags in the washing machine. Place in a clean washing machine on a cold rinse cycle with NO detergent and NO fabric softener. Always remove the paracord before placing in washing machine.

How to use the Brown Filter Bag:

Once you have found a source of water to be filtered make sure you have a suitable point to hang the bag from when its full of water. For example, use a tree limb, tripod or vehicle.

1. Start by thoroughly soaking the bag in water, massage the water through the bag to insure it is saturated.

2. Fill the bag to the top with water to be filtered. It sometimes helps to use a cup to scoop water in to fill the bag to the top.

3. Allow the water in the bag to flow down to the stitched line that’s runs across the front of the bag approx. ¼ of the way down the bag. Do not collect this water, allow it to run onto the ground. This helps remove any debris on the outside of the bag and prevent it from dropping into your collecting pot.

4. The water will take between 5-10 minutes to pass through a personal size bag. A group size bag will take a number of hours to filter. When using a group size bag a good technique is to allow it to filter overnight, you will then have a stock of filtered water ready to disinfect the following morning.

5. Once the water has been filtered it must be purified. Although it may look clean, it may contain pathogens which need to be removed by purification. The water can be purified by being brought to a rolling boil for 5-6 minutes, adding chemicals or using a purification system.

After use and care:

After each use turn the bag inside out and remove any built up sediment and debris. You can wash it out in clean water or allow the bag to dry out, this enables you to knock the dried sediment out once dried. A nailbrush is also effective for removing dried sediment. Make sure the bag is thoroughly cleaned and dried before storing away for your next adventure!
