An affordable option for traveling abroad, although you’ll want to keep it upright to avoid leaking and be careful not to drop it. Whilst travelling in Pakistan this last spring, I got another reminder of just how prolific plastic bottle use is. Many parts of Pakistan have serious plastic overuse and pollution issues.

Thirdly, you cannot use the Steripen for murky water as suspended soil particles in the water can shield microorganisms from the UV light, thus preventing them from being killed in the process. It’s a lot more expensive than the Sawyer Mini (coming in at a similar price to the Steripen and Grayl) but looks like it could be an excellent alternative. Durability: built tough to perform in harsh conditions and withstand 10 ft drops (full of water) onto concreteA Grayl water bottle is armed with a filter, so you don’t need to buy a water bottle and then a filter system. You dig? That said, the bottle itself is as tough as nails and can even survive a 10-foot fall when full of water!

Because gravity, rather than your hands, is doing all the work, this version of the Sawyer is a lot more durable. Additionally, the Sawyer Mini filter that comes with it has the same long lifespan – 100,000 gallons of water or, what the manufacturers claim is equivalent to a lifetime of water. Add into the mix the range of prices, sizes, and exactly what they safely remove from the water, and you can be left feeling completely perplexed. Testing standards: independently tested by a certified laboratory to meet or exceed NSF/ANSI protocol 42 and 53 for pathogen and chemical removal; meets the the United States Environmental Protection Agency's Guide Standard and Protocol for testing microbiological water purifiers. Filters: particulates (i.e. silt, microplastics, etc.); activated carbon effectively adsorbs chemicals, pesticides, heavy metals, flavors, and odors Certainly, there is no shortage of water bottle filter combination systems out there. But in my experience, if you want the best-of-the-best, go with the new 24 0z. Grayl GEOPRESS. For true hydration freedom whilst travelling or hiking, no water bottle will do more to protect your body and keep you hydrated no matter what crazy corner of the world you find yourself in.I’ve personally used the Steripen Adventurer for close to five years and find it the most convenient and easy-to-use travel water filter for travel on the market. There are certainly other, lighter filter options out there. Take the Sawyer Mini, for example. In terms of weight, the Sawyer Mini is hard to beat.
