Some types of soft hardwoods may ask you to drink straight from the stream, but this is a good way to swallow disease-causing parasites or bacteria. whether you campingAnd rowing, or backpacks For days without a potable water source, spending time treating your H20 with a water purifier will ensure you stay hydrated and healthy.
Boiling water is the simplest way to make it safe to drink, but it can waste a lot of time and fuel. Alternative methods include filtration, which removes bacteria and protozoa as well as any dirt or sediment, and purification, which does all of the above and also kills viruses. UV lights do all of that, too, but require a battery or solar charging. Finally, chemical treatments like iodine tablets are very compact, but they can sometimes leave a funky aftertaste.
To help you choose from all the different options, we’ve rounded up some of the best devices for every method of cleaning drinking water. Grab one of these to grab a drink when you’re miles from a tap.

Geopress deserves to be at the top of this list simply because it is so satisfying to use. There is nothing else like it on the market. Simply dip the outer container into a lake or stream, place the small capsule inside and squeeze the lid. In about 15 seconds, you’ll have 24 ounces of clean, drinkable water.
Geopress removes global waterborne pathogens, pesticides, chemicals, heavy metals, and microplastics, and improves the taste, aroma and clarity of water. Although it weighs 15.9 ounces, our testers were happy to get a 30-mile ride recently at the Four Pass Loop in Colorado. One note: After about 350 presses, Grayl recommends replacing a file purifier cartridge ($30).

Catadine Micropure Purifying Tablets

Some travelers in remote countries bring these tablets as a backup because they are practically weightless and have a long shelf life, but it is perfectly fine to use them as a first line of defense. One tablet will clean one liter of water, so you won’t have to do any complicated calculations on the road. However, it does take a while to work: 15 minutes to dissolve and destroy most viruses and bacteria, 30 minutes for Giardia, and four hours for Cryptosporidium – which most other water-based disinfectants don’t clean. Users say the tablets only create a mild chemical taste, but that unlike scrubbers or filters, they won’t remove silt, odors, or unpleasant flavours.
