The 9 Water Purification Methods: What They Treat and their Pros and Cons

Having a water purification method is one of the most important parts of disaster prepping. But it is also one of the most confusing.

There is a LOT of information out there about water purification systems, and a lot of the info is purposely misleading because companies want you to buy their products.

The reality is that there is no one “best” method of purifying water in disaster situations.

Which water purification method to use depends on your situation and the types of threats present.

For example, a water treatment system designed for backcountry use where viruses aren’t likely probably won’t be safe for treating flood water in an urban environment.

Here is an overview of the 9 methods of disaster water purification and the pros/cons of each written by Diane Vukovic here.

My only complaint is that eventually, backflushing won’t be enough. These can clog up after some time and no amount of back flushing will fix its low flow. I went through 2 on the AT. However, it will attach to Smart Water Bottles and most bladders!

Built for backcountry reliability and portability, the Sawyer Squeeze filter is our pick for the best portable water purifier.

The Sawyer Squeeze was (by far) the most common Pacific Crest Trail water filter this year – for the fifth year in a row. It’s a $39, 3 oz / 85 g hollow fiber filter that rids your drinking water of protozoa and bacteria (and floaties). It can be used with Sawyer bags (included with the filter) or with compatible water bottles (Smartwater is the bottle of choice for many hikers).
