Water is always going to be at the top of your priority list in a survival situation. After air and shelter from the elements, nothing is more important to life than clean drinking water.
Drinking straight from a stream, river or lake can spell disaster. Dysentery and other GI tract ailments can leave you dehydrated – and possibly dead.
You need to keep your hydration levels up in order to keep functioning properly. Dehydration has massive negative effects on the human body and these will start to show very quickly. The survival rule of threes says that you can survive three days without water; however by the time day three arrives you will be in no condition to even stand any chance of survival.
In a shtf situation, we will all need ways to filter and purify our water so it is safe for us to drink.
Here are some options to consider for portable filters to provide safe drinking water.
Lifestraw Personal Water Filter
This is a fantastic and one of the most popular portable water filters. As the name suggests, it is used as a straw to drink from any river or water source which may not be naturally safe to drink. Each straw can filter up to 1000 litres (264 gallons) of water.
In my opinion one of the best features of the Lifestraw is the way it does not allow you to suck up any water once it has filtered 1000 litres. This means there is very little chance of you drinking contaminated water. The more water it filters the harder it is to draw water in to. This will give you a very clear indication of how much life is left in the straw. This filter has an indefinite shelf life providing it is kept at room temperature. The main downside to the Lifestraw is that there are no replacement filters. Once it has filtered 1000 litres of water you will need to replace it with a new Lifestraw.
Water purification drops
Water Treatment Drops are very effective at removing harmful elements from water. Most drops consist of Chlorine dioxide. The main downside to some of the drops available is that you have to add the drops to your water and leave for one hour to ensure it is effective against all bacteria, pathogens and viruses. This means that this purification method is very time consuming. Another downside is you are actually adding a small amount of chemical to your drinking water. Although this won’t necessarily be harmful to you, it could cause adverse reactions to some sensitive individuals.
Water purification tablets
Tablets are a very easy method to purify water. Simply drop the required amount into your water – leave for between 30 – 60 mins (depending on brand) and you have safe drinking water. The tablets usually contain chlorine or iodine. Both of these tend to leave a funny taste in your water but they are very effective at making the water drinkable. They come in small packets which are easy to carry and store, which is another positive aspect of this method.
Water to Go Bottles
Water-to-Go have created some of the most impressive water bottles I have ever seen. With the help of technology originally developed for NASA, they have managed to design and create a water bottle and filter that makes any water source (apart from sea water) safe to drink!
The Water-to-Go filter is a sophisticated design. Eliminating 99.9% of all contaminants in water is no small feat! The filter has 3 technologies with each one adding an additional layer to the effectiveness:
Mechanical filtration. A very small pore size which stops contaminants passing through.
Electrical (by a positive charge). Reduces the pore size even further and attracts the contaminants like a magnet would. Trapping them inside the filter.
Carbon (contained within membrane). Instead of using adhesives to glue carbon particles together, (which vastly reduces the carbon’s efficiency) it is contained within the membrane. This helps to reduce contaminants whilst eliminating bad tastes and odours.
Water-to-Go filters remove bacteria, viruses, water borne disease, protozoa, heavy metals such as lead and harmful chemicals! It really is extremely impressive what this filter can do.
