The Whats and Hows of LifeStraws

If you love hiking, you know that water is a topic that requires careful consideration, particularly when the weather is hot. It would be impracticable to bring large buckets of water with you on a lengthy run. There may be streams, small waterfalls, and small ponds along the path, but the water in them may not be suitable to consume. This filthy water may be teeming with bacteria and other objectionable substances that you should never consume.
What if there was a compact, readily transportable device that could solve this issue?

Definition of a Life Straw

LifeStraws Australia wide available is a tube approximately 23.5 centimetres in length and 2.5 centimetres in diameter. A thread is affixed to the unit’s durable plastic exterior so that users can wear it around their necks. A user merely inserts the LifeStraw directly into the water source and consumes it as with a traditional straw.
The original LifeStraw contained iodine to eradicate microbes, but the 2012 model is chemical-free. Rather, the product utilises mechanical filtration. When you breathe on a LifeStraw, water is forced through hollow fibres with apertures less than 0.2 microns in diameter, thereby making it a microfiltration device. The fibres capture any grime, bacteria, or parasites while allowing clean water to pass through.

LifeStraw at Work

LifeStraw is a portable water filter that is compact and great for your first outdoor backpacking adventure . It enables you to imbibe directly from rivers and lakes, or from a container containing water you’ve gathered up from these water sources. Simply insert the bottom end of the LifeStraw into the water and drink through the upper end. 
Essentially, it is a straw with a filter integrated into it. After each use, backflush the filter by forcing air into the orifice to expel any residual water. If you have access to pure water, you should syphon some into the filter and backflush it. Give it a few spins and allow both ends to dry at room temperature with the caps off.
Both the family and individual LifeStraw models filter out detritus, bacteria, and parasites from potable water. The personal filter can block particulates as small as 0.2 microns, allowing it to filter out microscopic microbes and parasites. Both models are equipped with filters that remove 99.9999% of bacteria and 99.9% of parasites from the water. (As previously stated, only the family version can block infections.) It’s important to note that neither version removes heavy compounds or sodium, so don’t expect your LifeStraw to purify arsenic-contaminated water.

Family Size Life Straws

The LifeStraw Family is a larger instrument that can purify water for multiple persons simultaneously. According to the manufacturer, this higher-capacity product can accommodate a family of five for three years or approximately 18,000 litres. The product consists of a blue bucket containing a prefilter insert, a long plastic tube, and a filter cartridge with an affixed faucet for drawing water. There is no need for electricity or battery power. The water is guided through a series of filters by gravity.
The user fills the prefilter and receptacle at the top of the unit with water which then travels down the tube and passes through the same hollow fibre technology as the personal LifeStraws Australia, but the perforations are 0.02 microns wide, making it an ultrafiltration device. (It also implies that the family unit can filter out viruses while the individual unit cannot.) 
The valve can then be used to discharge the newly purified water. The individual can clean the filter by closing the faucet and striking a red squeeze bulb to discharge the collected residue. The prefilter bucket can be cleaned with a cloth. LifeStraw Family can filter approximately 9 to 12 litres per hour.

Humanitarian Distribution of LifeSavers

25% of New Delhi’s 16 million residents do not have access to flowing water. By 2015, the United Nations aims to reduce by half the number of people without access to sustainable water. Although excavating new wells and constructing water treatment facilities are viable solutions, some experts believe that personal filtration systems are a more effective way to create clean water. 
Studies have demonstrated that filtration is the most effective method for preventing diarrhoea. It has been demonstrated that purifying water at the domestic level is more than twice as effective at preventing diarrhoea as treating water at the source. In light of this information, numerous humanitarian and disaster relief organisations prioritise water treatment technology at the point of use. Obviously, prices will differ depending on when and where you purchase a product.
