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.

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.


Features To Look For When Choosing a Hydration Bladder

Opening Size

  • The larger the opening size, the easier it will be to fill, and to clean.
  • Reversibility

  • Being able to flip the reservoir inside out makes it a lot easier to clean effectively.
  • Taste

  • With some bladders, a plastic taste from the material or coating will be present in the water.
  • Add ons

  • There are water bladders that support additional pieces, such as clips, and filtration pieces.
