The WellVio Viostraw is a compact and efficient travel water filter from WellVio that gives you access to clean drinking water wherever you are. The filter uses advanced two-stage filtration with activated carbon from coconut shells and an ultrafiltration (UF) membrane that removes bacteria, microorganisms and contaminants down to 0.1 micrometres. Perfect for hiking, camping, travel and emergency situations.
With a capacity of up to 1000 litres for the UF membrane and 500 litres for the carbon filter, the Viostraw is a reliable companion for extended adventures. The compact design weighing only 90 grams makes it easy to pack in your backpack. Thanks to the 28 mm thread, you can also filter water directly from standard PET bottles.
The Viostraw combines two powerful filtration technologies in an easy-to-use format. The activated carbon adsorbs chemicals, chlorine and unpleasant tastes, while the UF membrane acts as a nano-fine sieve that stops bacteria and parasites. The filter comes with an extra PP pre-filter for very turbid water, which extends the lifespan of the main filter.
