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.

The timer gets pressed when you first activate your filter. It’s easier to press it against a hard surface.

The button should pop and a red strip appears in the small box on the left. This is now activated. 

The smaller box will turn red very quickly. The larger box will slowly fill up and after 2 months will be completely full. It is not affected by how much water is passed through. 

The filter is effective for 130 litres.

Using the GO! bottle 3-4 times per day the filter will last 2 months.

No. The filter is good for 130 litres when using the GO! Water bottle or 200 litres for the 75cl water bottle. In practical terms this means that you can fill up the GO! Water bottle 3-4 times a day, every day and the filter will last 2 months. Using the 75cl water bottle 2-3 times a day the filter will last for 3 months. If you stop using your Water-to-Go filter it will dry out and will need to be re-activated. 

To reactivate it just 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.

There are three ways: –
1) If you have a GO! Water bottle, and you have set the timer when you began using it, the timer will remind you to replace your filter after two months.
2) If you have a 750mls bottle and have registered with Water-to-Go, an email will be sent to remind you after three months.
3) One of the three technologies in our filter (the one which controls the taste and the smell) is carbon. We program just enough carbon into the filters to expire at either 130 litres or 200 litres. The filter will still be filtering bacteria, cysts and harmful contaminants; the water after this time will gradually start to taste and smell as it did before using the Water-to-Go bottle. This is a ‘sensory’ prompt for you to change the filter.

Yes. See our testing results. 

Our filters use both alumina nano technology and carbon to filter out fluoride.

Yes. Recent tests show that Water-to-Go filters reduce the amount of chlorine in the water to below detectable levels. You can see our testing results,also you can taste the difference when you drink from a Water-to-Go filtered water bottle.

By choosing a Water-to-Go bottle you reduce plastic pollution and save resources. Pollution caused by millions of plastic water bottles floating in our oceans damages wildlife and the planetary ecosysytem. Making just one Water-to-Go water bottle instead of a hundred single use single-use plastic water bottles preserves valuable natural resources.  Huge quantities of oil, water and other materials are used in the manufacturing and shipping process of single-use bottles. At the end of their lives, only 12% of plastic bottles are recycled!

For users of the 750mls water bottle, 4 replacement filters a year, would provide 800 litres of water which would cost around 9 cents per litre for the filters used.

For users of the GO! Water bottle, 6 replacement filters per year processes 780 litres of water which would cost just over 11cents per litre.

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.

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.

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. 

Try filtering water from your domestic filter and taste the difference!

The GO! bottle weighs 98g (empty with dry filter). 

The 750mls bottle weighs 138g (empty with dry filter).

BPA ( or bisphenol A) is a carbon based compound that is widely used to make plastic based products including CDs and water bottles. There has been a lot of research done to indicate that BPA poses a serious risk to humans and the environment.  Find out more about BPA at

Yes; all the product components (bottles, lids and filters) are BPA free and all materials used are approved by the FDA (Food and Drug Administration) in the USA. Our core guiding principles (see Our Mission. ) are to protect people and the planet.

This may reduce the efficiency and lifespan of the filter; however if you want to use your Water-to-Go bottle to carry other liquids, you could simply unscrew the filter, take it out, and use the bottle as a standard sports drink bottle.

The filter membranes are manufactured in the USA and all other parts are assembled in Water-to-Go units in Thailand.

This noise is caused by the ‘breather valve’. Simply unscrew the lid, turn upside down, gently move the bottom part of the breather (a mushroom shaped dome) up and down, two or three times; this will cure the problem.

This is a frequently asked question – and whilst the filter could be used to filter urine in extreme emergencies, Water-to-Go strongly recommends against filtering and consuming urine.

The 3 in 1 technology used in our filters is so unique we have created a seperate page telling you all about what makes Water-to-Go different from everything else on the market.
