Nothing is as important when backpacking as having a clean, reliable source of drinking water. Never drink untreated water. What you can’t see really can harm you. Even if a water source looks perfectly clear, all bodies of water have microorganisms, bacteria or viruses. The last thing you want on a hike is a case of diarrhea.
When searching for the appropriate water purifier for your needs, the first thing to consider is how exactly you will be using the purifier or filter. Do you need a filter to remove larger particles, parasites and bacteria or a purifier that will filter out all of these and disable viruses as well? How quickly do you need the drinking water be ready for use?

A simple bottle filter will work for some treks, but a more sophisticated process may be needed in most cases.
Choosing a Water Cleaning System
When shopping for a water filtering or purifying system there are some things to take into consideration.
- Does the process meet EPA guidelines for safe drinking water?
- Weight is important if you plan on a long hike and every ounce counts. Is it something you can use easily?
- Some of the pump action filters may be a little difficult to pump. Does it meet your needs?
- In the area where you will be traveling, are water borne-viruses a problem? If so you will need something more than a simple filtering system.
Whatever type of water purifying you choose you can extend the life of your filter by straining large pieces of sediment through a coffee filter or cloth. This can help keep your filter effective, longer.
