FAQ

Super easy. Just fill, replace lid and drink. To drink, sip/suck water through the filter. Avoid excessive squeezing. The filter purifies water as you drink. No pumping, iodine tablets or chemicals required.

If you are unfamiliar with water filter bottles, the flow rate is slower than regular water bottles. This just means the filter is doing its job of removing contaminants as you draw water through the filter. 

Water-to-Go’s unique 3-in-1 filter offers extreme protection from water-borne illness. In lab tests, the filter captured even the smallest of viruses like polio, which can be as small as .03 microns. In all, Water-to-Go filters viruses, bacteria, parasites (including giardia), chemicals, pesticides, heavy metals (lead, arsenic, chromium), and microplastics.  Water-to-Go has been proven in independent lab tests and by explorers who trust Water-to-Go on extreme adventures worldwide. 

The filter combines physical (small pore size), chemical (activated carbon), and electropositive nanofiltration. Picture a nanofiber mesh 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. By nature, most contaminants 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. No other water filter technology combines these three technologies and delivers results at such a low cost per gallon or liter.

Before first use, fill the bottle to submerge the filter for 15 minutes. That’s it. You are good to go. If used regularly, the filter only needs to be activated once. You do not need to activate the filter every time you use the bottle.  If your filter dries out completely (usually because it has not been used for several weeks), just reactivate by submerging the filter for 15 minutes and your bottle will be ready for use. You can safely reactivate the filter three times and get multiple vacations/trips from just one filter.

The lid probably needs to be tightened a bit. Give it a gentle extra twist. Gently suck to pull water through the filter. Don’t squeeze.

In general, filter life is determined by use, not time. So if your bottle sits on a shelf for months and the filter dries out, just reactivate the filter by filling the bottle to submerge the filter for 15 minutes. Without activating the filter, in the original packaging, the filter will have a shelf life of three years. The nanotechnology in the filter is activated by contact with water, so before initial use please keep your filter in a dry place.

In general, you can fill up the bottle at a tap 2-3 times a day and the filter will last for 3 months.

• Filters 200 liters/53 gallons depending on use. For example, if you are filtering water with heavy silt or sediment, filter life will decrease.
• Replaces 400 single-use plastic bottles.

In general, the filter will last three months. After three months of cumulative use we recommend replacing your filter. If you bought your bottle from the Water-to-Go website we will send you a reminder after three months to suggest you replace your filter if you use it regularly. If you are traveling to a part of the world where the water is particularly unsafe we recommend changing the filter every two months. 

Yes, all Water-to-Go bottles come with a filter attached to the lid.

You can buy replacement filters at watertogousa.com, watertogocanada.com and on Amazon.

No. Fresh water only.

Water-to-Go bottles are designed to purify water as your drink. They are not designed to fill another vessel. You can easily get water from the bottle to brush your teeth but filling a glass or pot is not recommended.

Dishwasher safe: Active bottles, Bioplastic bottles, and Classic bottles

Not dishwasher safe: Go! 18oz/50cl bottle (now discontinued in US/Canada) and lid are hand wash only. 

In all cases, please remove the filter before cleaning. 

The filter is not designed to be flushed.

Yes. We can make custom bottles using your logo. We have done this for several large organizations and charities able to guarantee a large initial order to cover the design costs of putting your logo on a Water-to-Go bottle. For more information please contact info@watertogo.co

Water-to-Go Active and Classic bottles are made of FDA-approved BPA-free plastic. 

Water-to-Go Bioplastic bottles are made from ethically harvested sugarcane (except the lid and filter shroud). The sugarcane bottle is produced with 60% less energy and 40% less greenhouse gasses than regular plastic bottles. 

All Water-to-Go bottles are fully recyclable. The filter medium itself is compostable.

Water-to-Go is a twelve year old British company with over 500,000 happy customers around the globe. Water-to-Go's mission is to provide safe drinking water without single use plastics that damage the environment. To accomplish that we design, manufacture and distribute personal water purifier bottles that filter water-borne contaminants that can cause illness. We protect travelers, outdoor adventurers (hikers, campers, mountaineers, anglers), families concerned about the quality of tap water and those preparing for emergencies and natural disasters.

There are two things that make Water-to-Go different:

• Better protection for people. Unlike most filter bottles, Water-to-Go filters dangerous viruses like hepatitis.
• Better protection for the planet. In addition to a filter that replaces 400 plastic bottles, Water-to-Go offers the only bioplastic water filter bottle, made from sugarcane. Plastic from plants, not petroleum!  We are in the process of moving all our bottles to bioplastic. 

Before first use, fill the bottle to submerge the filter for 15 minutes. That’s it. You are good to go. If used regularly, the filter only needs to be activated once. You do not need to activate the filter every time you use the bottle.  If your filter dries out completely (usually because it has not been used for several weeks), just reactivate by submerging the filter for 15 minutes and your bottle will be ready for use. You can safely reactivate the filter three times and get multiple vacations/trips from just one filter.

Powders will be captured by the filter. If you want to use your Water-to-Go bottle with powders, unscrew the filter from the lid and use water from a safe source.  When you need to use your bottle to filter water, screw the filter back onto the lid. Any residual powder in the bottle will be captured by the filter. Having an extra filter may be helpful since powders and sediments reduce filter life.

While the filter could be used to filter urine in extreme emergencies, Water-to-Go strongly recommends against filtering and consuming urine.

No, the filter will not work effectively if it is frozen. If the filter does get frozen, make sure that it is fully defrosted by filling the bottle with lukewarm water before using it again. You can still fill the bottle with snow or ice and use the bottle in cold climates but it is important to ensure the filter doesn’t get frozen by keeping it in a bag, sleeping bag, close to your person etc.
