A Safer Bottle for the Earth and Adventure Riders
This is the first filtered water bottle I’ve tried. All I have to compare it to is regular bicycle bottles. Because of that, my overall rating and my Nots (above) might make it seem like I don’t like Water-to-Go’s ACTIVE bottle, but that’s not true.
I actually think they’re onto something important with their filtered bottles. And that if you’re a cyclist who might fill up out of a stream, a public tap or other questionable water source on rides, that it might be perfect for you.
Safer for the Planet and You
What’s so important about Water-to-Go’s products is that if a person uses one of their ACTIVE filtered bottles instead of buying single-use plastic water bottles, it could prevent up to 400 bottles ending up in a landfill.
And in these times when we’re so concerned for our health, their filters are claimed to remove most harmful contaminants to create safer cleaner water. Read more here about Water-to-Go’s extensive testing: https://watertogousa.com/how-it-works/testing/.
Long Lasting Filtration
The filter in the ACTIVE bottle will last up to 200 liters or 53 gallons depending on use (the dirtier the water filtered, the quicker a new filter is needed). The water flow rate slows as the filter wears out, which indicates it’s time for a new one.
Water-to-Go says that in general use you can fill up the 26oz/75cl water purifier bottle two to three times a day and the filter will last for three months. Replacement filters come in a 2-pack for $39.99.
About Water-to-Go’s Filter Technology
Quoting from Water-to-Go, our “unique 3-in-1 filter offers extreme protection from water-borne illness. The filter removes up to 99.9999% of illness-causing contaminants, including those as small as a virus. The filter eliminates bacteria, parasites (including giardia), viruses (because of their small size, few bottles can remove dangerous viruses like Hepatitis A), chemicals (including PFAS), pesticides, heavy metals (lead, arsenic, chromium) and microplastics. If there is a danger in water that could make you sick, we likely remove it. Water-to-Go has been proven in independent lab tests and by extreme adventurers who trust Water-to-Go on extreme adventures worldwide.
3-in-1 means that Water-to-Go uses three types of filtration to protect you. Think of it as a net within a net within a net so almost nothing gets through. The three types of filtration are: Mechanical – 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 would, trapping them inside the filter;
Finally our filters use 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 while eliminating bad tastes and odors.”
To keep the nozzle contaminant-free, there’s a flip-top lid, while a breather valve in the lid helps the water flow. Even with this valve, I found that it was a little more difficult than I would have liked to take a good gulp of water. The filter restricts the flow rate and the plastic the bottle’s made of is stiff and less flexible than typical bike bottles. So I had to squeeze harder than usual.
I thought the filter built into the lid might make the ACTIVE bottle hold less than typical large size bike bottles (like my Camelbak Podium 24-ouncers). But Water-to-Go’s held the same. The ACTIVE bottle is translucent and marked on the side so you always know how much liquid is left.
There are two rubber grippers on the bottle, which help for holding and squeezing. I tried the bottle in a couple of different cages, and the lower gripper made it more difficult to get the bottle in. Also, the bottle’s 9.5-inch height means it may not fit into some frame-mounted cages on smaller bikes. There is a carrying loop on the bottle so you could carry it on or in a pack instead.
Speaking of that, if you did choose to carry it in a pack, you could use it to filter water to pour into another bottle mounted to your bike. That way you’d have easily accessed filtered water in a bottle that fits your frame and bottle cage and is a bottle easy to use, too.
Overall, I think the ACTIVE bottle is impressive and the only thing it would take for me to rate it even more highly is for them to make a model more dialed in for use on the bike while riding.

KEVIN B MILLER says
I have been using Britas filtered water bottle for years, never figured out why they are not used more by people who ride bicycles.
Jim Langley says
Thanks for the tip, Kevin. I didn’t know about the Brita bottles, only their pitchers. Here’s a link to a 26 ounce one: https://amzn.to/3maCYaI Not sure if this is the one you’re using.
On longer summer rides in the country, I carry a Katadyn BeFree collapsible water filter bottle. It takes up little room in a pocket when collapsed, and is easy to squeeze the filtered water into my regular water bottle. Katadyn is an established water filter company.
Jim Langley says
Thanks for the tip, Gary. Collapsibility is a great feature. I searched for it and found the BeFree is on Amazon, too. Here’s a link: https://amzn.to/3H03M5d
Appreciate you telling us about that water filter bottle!
