The filters used in our BPA free water bottles are created based on technology originally developed for the NASA space programme. Water-to-Go products filters in excess of 99.9% of chemicals, like chlorine and fluoride, heavy metals, like lead as well as bacteria and, importantly, viruses. They also remove any bad taste or smell from the water. We provide the technology that can prevent people getting sick, potentially saves lives and stops the World filling up with plastic waste.

Ice cold fresh water from the river... Ice cold fresh water from the river..., Terry Simmons

Water-to-Go bottles are fantastic for outdoors people. We took ours on a whitewater-kayaking trip in Norway and not only do you have fresh water but it is ice cold from the river even when the weather is baking hot!

We're in Nepal having survived the Earthquake and wanted to write to thank you for what turned out to be a lifesaving product!

Filtering Water on Everest... Filtering Water on Everest..., Darren Watts

"Day 1 on the way back down from Everest Base Camp. Famous memorial to climbers and Sherpa's who have lost their lives in the high mountains. The smug feeling when you watch people struggling with their filtration systems and you simply fill your Water-to-Go and GO!"

Safe water in Central African Republic Safe water in Central African Republic, Alexandra Simpson - UN Peacekeeper

"I work for the United Nations, Peace Keeping, and am currently based in Bangui, the capital of the Central African Republic. Having bought my Water-to-Go bottle in August 2015 it has become essential to me: I no longer need to buy bottled water (expensive and wasteful), as I have every confidence in drinking tap water, or water from ‘wilder’ sources. In the field or in the office, my WTG bottle is my constant companion!"


How does it work? +

Water-to-Go uses three different technologies forged together in one filter to filter over 99.9% of all contaminants in water. The medium used in the filter was designed for the NASA space programme and consists of:

A) Filter medium with one of the smallest pores sizes ever developed for water filtration
B) The traditional technology of activated carbon particles (that reduce bad taste and odours) used within the filter medium so that it is much more effective as there is less adhesive holding the carbon in place thereby providing a greater surface area for the carbon to work
C) The medium releases a positive hydrostatic charge when it comes into contact with the water
No other water filter technology combines these three technologies and delivers results at low cost.

Is it ready to go? +

Yes. All you need to do is ensure the filter is wet through and flush once to activate it. We suggest the first time you use a new filter you fill the bottle up and turn it upside down, submerging the filter for 15 minutes. Then gently squeeze out the contents until the water runs clear.
We have created a short video showing how to activate your filter.

Do you have testing reports? +

Yes. You can view these on our website, We have been tested on three continents by internationally renowned laboratories in London, Florida and Bangalore.
We have further test results coming in from additional laboratories in Europe.

What are the three technologies Water-to-Go uses? +

1) Water-to-Go uses mechanical filtration; a very small pore size which stops contaminants passing through.
2) 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.
3) Finally our filters use 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.
