Convenient Water in the Wilderness… Convenient Water in the Wilderness…, Luke Parry

Safe drinking water is an absolute must travelling long distance in areas of the wilderness when water is scarce and bottled water is unavailable. Water-to-Go bottle assures me with instant convenient access to water for both drinking and cooking on my worldwide expedition. Buying bottled water has now become redundant – some thing I’ve been reluctant to do unless absolutely necessary. The bottle is strong, durable and will not degrade giving me confidence of use for many years to come with its replaceable filter system. Unbelievably simple in operation it allows me to get on with my journey with minimal fuss!

Who needs to buy bottled mineral water… Who needs to buy bottled mineral water…, Charlotte Jones

Water-to-Go is a fantastic product for people from all backgrounds whether you are a sports enthusiast, athlete, office worker or keen walker! Great tasting filtered water every time saves me a fortune on bottled water. Not only do I save Money with my Water-to-Go bottle but I also save space as I can easily pop it into my bag empty and fill it up anywhere! If you love to have fresh great tasting water on the go then you need Water-to-Go!

Lightweight & Functional… Lightweight & Functional…, James Douglas

My Water-to-Go bottle is easily one of the best things i’ve bought. It’s lightweight, comfy to hold and can safely filter an awful lot of water! It’s tempting to go with something bigger, heavier, flashier and seemingly more high-tech, but it is lighter and more functional than most filters and, unlike something like a Steripen, I don’t have do drink dead bacteria! Mine is coming with me when I go off walking and I wouldn’t be without it in trips to Africa, Asia and South America. I can’t recommend it highly enough!

Perfect For Boating Perfect For Boating, Nicky Spence

My boat has a 50 gallon water tank which feeds water through the taps for domestic use but I’m reluctant to drink from it for fear of contamination from filling hosepipes etc, so I have bought one of these bottles, rather than take 25 litre bottles of water from home when I go boating. I have to say, I’m impressed. The bottle itself is ergonomically shaped making it pleasant to hold. The air inlet filter means that you don’t have to squeeze the bottle to get the water out. Being a dark colour and thick plastic construction, it tends to keep cold water colder for longer than other water bottles i’ve tried. The ‘flip up’ mouthpiece is easy to use thanks to a clever lever and it is a comfortable shape to drink from.


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.
