Hollow Fiber Advantage: Hundreds of tiny, hollow fibers, enable the microfilter to filter water faster than traditional filter media. There are a couple of versions of the Gravityworks now, the original had two hanging reservoirs, this one has one to hang somewhere with the clean side reservoir being a bottle - this format is easier to use once its full of clean water. Both the dirty resrvoir and the bottle receptacle are 2.0L. Effective: Every microfilter is individually tested to ensure it meets EPA & NSF guidelines for the removal of 99.9999% of bacteria and 99.9% of protozoa**.

We like Katadyn’s Micropur M1 tablets for chemical treatment, as they tend to leave a more subtle aftertaste compared to other brands. The SteriPEN Adventurer has been our go-to UV filter for its long lifespan and light weight.Another consideration here is location: if you are going to be traveling through a desert landscape, there may be few to no trees (a necessity to hang some gravity filters properly). For that type of setting, a different style of filter would be best. Over the last few years I’ve increased my amount of hiking and wild camping trips. In 2019, I tried out my first filter water bottle for my E2W Challenge, hiking 950-miles across Britain and it was a total game-changer! You can buy the filter part separately so you’d be able to replace that and keep your reservoir. Do you still use filter water bottles or is this a better option? Filters also come in different styles: straw-style, pump filters, gravity filters, and UV or tablet treatments. They all make water safe to drink but differ slightly in size, durability, and price. Group-ready: 8 liter (4.0L filtered + 4.0L unfiltered) total capacity easily supplies water for groups.

Filters like the Sawyer Squeezeand Katadyn BeFreeare popular because the actual filter unit is so small, and the weight is close to nothing. The Sawyer Squeeze weighs just a couple of ounces, while the Katadyn weighs 6.8 ounces (but remember, it can filter up to 3 L of water at a time). Pure Platy experience: The Platy 2.0L Bottle is taste-free, as well as BPA-free, BPS-free, and phthalate-free. Delivering four liters of filtered water is just 2.5 minutes with no pumping, there’s simply no easier or faster way to get safe water away from home. Ideal for bigger groups, the system’s eight-liter capacity eliminates both the worry and hassle of keeping plenty of water around for anything you need. We’ve tested this filter abroad and love it for international travel . It’s ideal for when you want to filter all tap water before drinking, and it works wonderfully as a constant companion to keep you hydrated on the go. Hollow Fiber Advantage: Hundreds of tiny hollow fibers enable the microfilter to filter water faster than traditional filter media.

Made in Ireland

Sleek, lightweight, and thoughtfully designed, the newly minted LifeStraw Go Series filter bottle is ready for a rowdy road trip across Mexico, or a casual day on the river. Its streamlined, stylish design joins forces with a 0.2-micron filter and 4,000 L lifespan to deliver a hard-working portable filter that’s equally at home on trail, or around town. I’m afraid the filter is good but it doesn’t turn dirty (muddy/peaty) water into clean water by sight! The 22-ounce bottle is a solid alternative option to the straw if you won’t be near water sources as frequently. The activated carbon filter reduces chlorine, organic chemical matter, and odors for a better taste than other filters we tried, making it a fine bottle to tote around on daily outings. As a solo hiker it was great that I could hike with less water and then filter on the go.But I was also able to help a few fellow hikers who were low on water during the hike, especially when the weather was insanely hot.
