Water To Go Replacement Filters utilise space age NASA technology to remove 99.9% of all microbiological contaminants in dirty water including bacteria, viruses, protozoa, cysts and heavy metals.

The advanced filters utilise a unique three layer system - mechanical filtration, electrical positive charge, and activated carbon - to trap contaminants, providing clear portable water. And unlike other filtration systems, the filters are completely recyclable. The casing and end caps can go in your plastic recycling, and the grey membrane can then go on your compost heap to biodegrade.

These replacement filters can only be used in Water To Go 500ml bottles. Just unscrew your old filter form the bottle cap and replace with a new one. They will treat 130 litres of water or last for two months.

Please Note: This filter will not work with sea water. Hand wash only.
