Filtered Water Bottles for Travel & Adventure

Access safer drinking water wherever your travels take you with a Water-to-Go filtered water bottle. Our 3-in-1 filtration technology removes up to 99.9999% of microbiological contaminants, including viruses, bacteria and parasites.

We’ve enhanced technology originally developed for the space programme to create our 3-in-1 filters, specifically designed for use in Water-to-Go filtered water bottles. They can deliver clean, safe drinking water, anywhere. This makes them the go-to bottle for any form of travel and outdoor activity.

Our 3-in-1 water filtration technology combines mechanical filtration, electropositive filtration and activated carbon to reduce microbiological contaminants and improve the taste and odour of drinking water.

The three technologies used in a Water-to-Go filter are:

Mechanical filtration a very small pore size which stops contaminants passing through.

Electrical (by a positive charge) which reduces the pore size even further and attracts the contaminants like a magnet would, trapping them inside the filter.

Activated Carbon our filters use activated carbon but instead of using adhesives to glue the carbon particles together, (which vastly reduces the carbon’s efficiency) it is contained within the membrane, helping to reduce contaminants whilst eliminating bad tastes and odours. Try filtering water from your domestic filter and taste the difference!
