The Swig™ filtering straw purifies non-potable water using an electro-adsorption process and acts against bacteria, viruses and other contaminants present in water sources.
It's ideal for emergency and survival situations (loss of water bottle, hiking, travel or natural disasters).
It uses the same NASA-derived filtration media as ÖKO water bottles.
The SWIG works by suction and can be stored anywhere given its size and weight (survival bag, backpack, handbag, travel bag or in an easily accessible place in the event of natural disasters).
