Below are some of our frequently asked questions. Can’t find what you’re looking for? Fill out our contact form and we’ll get back to you ASAP.

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.

How do I activate the filter timer on my GO! Water bottle

To activate your Timer, press the red button against a hard surface. The button should ‘pop’ and a red strip appear in the small box on left hand side. This is now activated. Put it in the bottle strap and after two months the larger box will slowly fill up red. When it’s completely full, it’s time to replace your filter.

If I don’t use my bottle everyday will it still only last for 2-3 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.

How do I know when my filter needs replacing?

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 75cl 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 programme 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.

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.

What is the pore size of the filter (in microns)?

When we talk about pore size we refer back to standard technology. The mechanical restriction of the size of the pores has been the traditional 
measure of what a filter will eliminate. This is not the case with Water-to-Go. We have a unique combination of three technologies, each performs individually but it is the combination that makes us unique. We have a combination of two nano technologies, which not only reduce the pore size to 0.7 microns, but also create a positive hydrostatic charge in the membrane which attract and traps even the smallest of viruses like polio (which can be as small as 0.03 microns). Have a look at our testing page to see our tests for the Polio Virus – Testimony to the fact that we achieve substantial results by the combination of technologies rather than depend on just the mechanical calculation via a limited pore size.

Do you filter Fluoride?

Yes. Our filters use a combination of both alumina nano technology and carbon to filter 99.9% of fluoride.

Do you filter Chlorine?

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

How does the bottle ‘save the planet’

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 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!

How much per litre would water cost via your bottles?

Water-to-Go bottles deliver safe drinking water at less than 7.5c per litre.

Do you have testing data?

Yes. You can view these on our website. We have been tested on three continents by internationally renowned laboratories in Europe, America and India.

Can you brand the bottles for companies and charities?

Yes, we can make bespoke bottles using your logos. For more information please contact [email protected]

Can I be a stockist?

Water-to-Go is currently looking for additional stockists in Ireland. For more information please contact [email protected]

Do you make jugs?

Water-to-Go specialise in portable filtration solutions so at this stage we do not offer a jug.

How much does the bottle weigh?

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

The 75cl bottle weighs 138g (empty with dry filter).

Are Water-to-Go products BPA free?

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.

Can I use other liquids in the bottle other than water?

We do not recommend using anything else but water with our filters. 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.

Where is the product manufactured?

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

My bottle keeps making a ‘tweeting’ noise… How do I stop this?

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.

Will the filter clean urine?

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.

Is it dishwasher safe?

The 75cl Bottles are dishwasher safe (bottle only – lid is hand wash only).

The 50cl GO! Bottles & lid are hand wash only. In all cases, please ensure you remove filter before cleaning.

Can I put my bottle in the Fridge?

Yes, Water-to-Go bottles can be left in the fridge.

Can I put my bottle in the Freezer?

No, the filters are not suitable for the freezer. Freezing the filter damages the membrane and impairs its performance. If your filter has been frozen, we would recommend replacing ASAP.
