The Water-to-Go™ filter uses a combination of two nano technologies, which not only reduce the pore size to 0.7 microns, but also creates 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).

The nanofiber mesh is made with activated carbon where each nanofiber strand has millions of tiny hairs that reach into the tiny pores of the mesh. Each of those tiny hairs carries a positive charge. Most contaminants naturally have a negative charge, so the contaminants that are not blocked by the tiny pores or trapped by the activated carbon are attracted to the positive charge and captured by those tiny hairs.

The 3-in-1 filter is like a net within a net within a net. 

Mechanical filtration:
A very small pore size which stops contaminants passing through.

Activated Carbon:
Water-to-Go™ filters use activated 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 odors.

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

The Water-to-Go™ Water Purifier filter removes/reduces:

• Viruses including hepatitis A, rotavirus and noravirus
• Bacteria including e.coli and cholera
• Protozoan parasites including giardia and cryptosporidium
• Chemicals and pesticides including PFAS and chlorine
• Particulates including microplastics and sediment
• Heavy metals including lead, mercury, and chromium

Water-to-Go™ filters use both alumina nano technology and carbon to filter out fluoride.

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

It is important to activate the filter before first use. To activate, fill the bottle to fully submerge the filter, let the filter soak for 15 minutes or longer, then empty the bottle. You only need to activate the filter the first time you use or if it completely dries out.

Filter replacement depends largely on how you use your bottle. For example, the filter in a bottle used to filter chemicals from tap water will last much longer than a filter in a bottle used to filter sediment-laden water from ponds and lakes.

The Water-to-Go™ Water Purifier filter provides 53 gallons (200 liters) before replacement. After this volume, the water will gradually start to taste and smell as it did before using the Water-to-Go™ Water Purifier Bottle. This is a ‘sensory’ prompt for you to change the filter.
