Mouthpiece – Safe water is now ready to drink. You just blow air through to clean the straw out and it’s ready to use again.
Filtration – Hollow fibres in the tube trap 99.9999 per cent of bacteria and 99.9 per cent of parasites and filter out any soil particles.
Plastic casing – Weighing in at just 56g (2oz), the straw is very practical for distribution and compact enough to carry with you 24/7.
Dirty water – The potentially contamined water is sucked up at the bottom of the device.
