How To Purify Water While Backpacking
The best way to purify water while hiking in the backcountry depends on knowing the type of impurities that are likely to be found in the waters you find.
Contaminated water sources are likely to contain bacteria, viruses, and microorganisms.
Any time you are drinking from a water source that is questionable, it is a good idea to purify first.
We also recommend bringing more than one way to purify your water, as a backup is also a good idea.
Water Filters
It’s important to be aware of the type of microorganisms common to the area, because of the size of the filter needed to filter them out.
Common protozoa like Giardia or Cryptosporidium are 5 microns or larger, and can be filtered out with most standard filters on the market.
Microfilters are needed to filter out bacteria in the 0.2–0.5 microns size range. This includes Cholera, E. coli, and Salmonella.

Chemical Treatments
Viruses are much smaller, in the range of 0.004 microns, and not all can even be filtered with a microfilter. Chemical treatments are needed to kill most viruses that are small enough for microfilters to let through.
Best Iodine Water Treatments
Iodine is sensitive to light, and should be stored in a dark bottle. It also works best on water warmer than 68 degrees Fahrenheit.
Iodine crystals provide an easy way to purify water for drinking.

Boiling
Boiling your water is the most effective way to purify it. After bringing the water to a boil (212°F / 100°C), let it boil for at least one minute to be safe.
At higher altitudes, the boiling time should be increased, up to three minutes.

Backpacking Hydration Bladder Recommendations
Backpacking Hydration Bladder Recommendations
Some people prefer drinking out of bottles, but the convenience of having your water easily available near your mouth makes it a lot easier to stay hydrated.
A hydration bladder, sometimes referred to as a reservoir, is a lightweight, flexible plastic or rubber container for water that has a tube with a mouthpiece to allow you to drink hands-free.
With a good quality hydration bladder, you’ll be able to drink while you walk without going in to your pack to get a bottle.
Hydration Pack vs Hydration Bladder
Hydration packs are backpacks that contain a bladder, but if you’re already wearing a backpacking pack with the rest of your gear in it, a bladder full of water can be carried in with the rest of your gear.
A lot of the best backpacking backpacks have a separate compartment meant for storing your hydration bladder, with an exit for the tube so it is reachable for drinking, and some have a clip to keep it in place.

Staying Hydrated While Backpacking
It’s important to stay properly hydrated while you’re hiking. If you’re out long enough you will eventually run out of the water you’ve brought with you, and be looking for places to fill up.
Whichever method of purifying your water you prefer, just make sure to bring and use it before drinking any water that may be contaminated.
