NOT to use this...
In the lower reaches of the Ganges, for instance.
I also would not
use a water filter bottle for drinking city water from Third
World cities. Or, at least if I did I would treat it with AquaMira,
The reason is the pore size in these and other water bottles - they're
too large to filter out viruses and small things. Things like typhoid
and polio and cholera. A few water bottle companies treat their filters
with iodine. It tastes. Plus, I don't trust them when it comes to the
bad stuff that can result in your body being sent home in a box.
But for the vast majority of North America, and some places in the Third
World, these water bottle filters work fine because you mainly have
to worry about giardia - which are huge in size by filtration standards
and are easy to filter out. And the large pore size of the water bottle
filter allows water to go through much easier than a standard filter.
Easier drinking. Our recommendation:
- A Water Bottle
Fitler for quick, cold water in clear water streams and springs in
- AquaMira (the
chlorine dioxide discussed on this web site) to treat questionable
water, and for treating larger quantities at camp.
- Both of the above
are easy, very lightweight and work excellently together. And they
are realtively inexpensive.
Favorite Water Bottle filter
Some of the water
bottle filter advantages:
- Everyone in a
group has their own filter. With only one or two pump filters for
a group, it gets to be a lot of work. Typially with only one filter,
one person goes to the stream and filters water for everyone. And
people screw up, dunking the hose in the stream, backwashing, etc.
Mistakes when you are tired are very common, and you're drinking this
The filters in each
bottle are easily replaced. They'll go through about 200 liters (quarts)
if water clarity is decent. Filter muddy water, and they clog more quickly.
We like to use water bottle filters ($9.79 filter replacements) in muddy
water rather than the more expensive pumps (filter replacement for $20
We usually suggest you get at least one replacement filter replacement
