COMPLETE PROTECTION: protects you from all the nasty things in water that can make you sick. The unique patented 3-in-1 filter technology removes up to 99.9999% of all contaminants (bacteria, viruses, parasites, pathogens, metals and chemicals like chlorine, fluoride, lead and microplastics) from any freshwater source. It purifies and filters water while you drink with no need for plunging, iodine, chemicals, or batteries.

LONG-LASTING FILTER: Each of the replaceable filters provides 50+ gallons of clean water (roughly every 3 months)

LOWEST COST WATER FILTRATION: Water-to-Go water filter bottles provide the highest level of protection at the lowest cost per fluid ounce.

NON-TOXIC AND ECO-FRIENDLY CONSTRUCTION MATERIALS: All materials used to make Water-to-Go products are BPA free & FDA approved.



The filter works instantly to protect against bacteria, parasites and microplastics,  reduces chemicals like chlorine and improves water taste.

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

  • Mechanical filtration; a very small pore size which stops contaminants passing through.
  • Electrical (by a positive charge) which reduces the pore size even further and attracts contaminants like a magnet, trapping them inside the filter.
  • Activated carbon -our filters use activated carbon without using adhesives that would vastly reduce the carbon’s efficiency. Instead, the activated carbon is contained within the filter membrane itself. This technique helps further reduce the contaminants while also eliminating bad tastes and odors.

The filter is an ideal deal for hiking, camping, international travel and emergencies, it allows you to take any non-salt water from a stream, river, or tap and filter it instantly.  Once the filter is activated and your bottle is full you are ready to drink, no need to remove the lid and filter until you’re ready to fill your bottle again.
