How it works

Our Water Bottles use a Unique 3-in-1 Filter Technology

The filters used in our BPA free water bottles are created based on technology originally developed for the NASA space programme.

Water-to-Go’s 3-in-1 Technology

Our reusable, BPA free water bottles contains our own unique 3-in-1 filtration technology effectively providing clean safe drinking water from any non-salt water source around the world. 

Three different (1 traditional and 2 nano) technologies are combined in one filter cartridge to remove up to 99.9999% of microbiological contaminants in water. 

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

Mechanical filtration – A tiny pore size, so small contaminants can’t fit through.

Electrical – A positive charge reduces the pore size even further and attracts contaminants like a magnet, trapping them inside the filter.

Activated Carbon – Unlike most carbon based filters, 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 tap at home and taste the difference!

Water-to-Go filter bottles deliver safe, healthy water worldwide

Water-to-Go filters remove bacteria, viruses, waterborne disease, protozoa, heavy metals such as lead as well as harmful chemicals.

Our filters remove Chlorine and Fluoride from tap water.

The filter will eliminate harmful contaminants from the water but allow beneficial minerals such as sodium and magnesium to pass through leaving you with the healthiest water possible. 

Water-to-Go filters have been independently tested against internationally recognised standards by industry specialists including The London School of Hygiene & Tropical Medicine (UK), BCS Laboratories (USA), Bangalore Test House (India) and IMI (China).

Use Water-to-Go products and you’ll be healthier, wealthier and helping to make the world a better place!

Depending on filter size, each Water-to-Go filter is able to replace 260 or 400 single-use plastic water bottles!

They ensure you have access to safe water anywhere in the world without ever having to buy environmentally damaging bottled water.

Our water bottles deliver safe, clean drinking water at just 5p per litre.

The filter membrane is biodegradable and the shrouds are recyclable. 

Our water bottles are used and approved by everyone from backpackers to commuters, gym users to expecting mums. Have a look at some of our testimonials. Perfect for everyday, outdoor and travel.

Filter Facts

Water-to-Go filters come in two sizes; the 75cl filter which filters 200 litres of water lasting 3 months, or the 50cl filter lasting 130 litres and 2 months. Each delivers the same filtration results, having been tested extensively in the USA, UK, India and China. 

Our unique 3-in-1 filtration technology utilises a combination of Nano alumina along with activated carbon and other filtration ingredients to bring about this amazing process. The nano alumina emits a positive charge when wet and attracts the negatively charged contaminants within water including protozoa, bacteria and viruses. This revolutionary process will leave every drop of water safe, healthy and tasting great. A filter that really does what its supposed to do.

One Purpose.

To give you clean safe drinking water, anywhere.

Unlike carbon block filters that lose as much as 70 percent of their area to the adhesives that hold the block together, our carbon has zero adhesives holding it in place making it far more efficient. Even so the pore sizes of carbon block filters are too big to stop all protozoa, bacteria or virus and only filter chlorine and some heavy metals. They basically improve the taste of water without properly filtering out any of the more dangerous contaminants. The two additional nano-technologies inside the Water-to-Go filter reduce pores to such a small size that no protozoa, bacteria or viruses can fit through.

The Bottom Line

We have tested the filters and the list of materials that Water-to-Go will catch and eliminate is a long one. Water-to-Go filters reduce the volume of contaminants in water by up to 99.9999%. Simply put, they work!


Water-to-Go filter technology has been independently tested against internationally recognised standards by industry specialists in the USA, UK, China and India. All have confirmed that the filters in the Water-to-Go bottles eliminate up to 99.9999% of harmful contaminants in water.

We’ve had results from testing houses including The London School of Hygiene & Tropical Medicine (UK), BCS Laboratories (USA), Bangalore Test House (India) and IMI (China).

What are Total dissolved solids (TDS) and are they harmful?

Total dissolved solids (TDS) are the amount of organic and inorganic materials, such as metals, minerals, salts, and ions, dissolved in a particular volume of water; TDS are essentially a measure of anything dissolved in water that is not an H2O molecule. So not all TDSs are bad!

“Our filters are built with the specific aim of removing harmful microbiological contaminants and harmful heavy metals and chemicals. They are neither designed nor built to remove all TDSs. In fact, the technology delivers a minute positive electrostatic charge which works like a magnet in the filter attracting and trapping harmful elements even as small as viruses. Given this charge is positive, positively charged salts, which are beneficial for our bodies, pass through the filter. Calcium and magnesium salts are examples that would be ‘filtered’ out by other technologies.
At no stage has Water-to-Go advertised nor would we ever claim to remove all TDSs. We are internationally tested and validated on three continents. Results show we filter heavy metals, naturally occurring contaminants such as raw arsenic and cadmium, chemicals such as Chlorine and Fluoride and all microbiological contaminants including viruses.”

WtG vs Carbon Filtration

The Difference between Water-to-Go and Carbon Filters

Based on a combination of 3 technologies, the filters used in Water-to-Go bottles are uniquely different to the activated carbon filters used in other water bottles. Activated carbon filters will take out sediment and some other materials, whilst Water-to-Go increases your drinking safety by taking out much more, including:

  • Metals including lead and chromium
  • Dangerous chemicals including “VOC”s (volatile organic compounds) and fluorides
  • Disease carrying bacteria e.g. E. coli, Cholera and Typhus 
  • Sickness inducing viruses such as Hepatitis A and Norwalk viruses 
  • Potentially fatal parasite eggs (known as Oocysts) like Giardia lamblia

In addition to the nano-technology used in our filters, activated carbon is also used. However, instead of glueing them into a block (like most carbon filters) and losing efficiency, we incorporate it into the membrane and is used solely to improve the taste and smell of the water.
