The water filters at a good speed! No waiting around for your water, you can fill, filter and drink! 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).

The Katadyn BeFree system can filter smaller particles down to 0.1 microns. The majority of reviewers love that it’s both easy to use and clean.Effective: Every microfilter is individually tested to ensure it meets all EPA & NSF guidelines for the removal of 99.9999% of bacteria and 99.9% of protozoa*. *This includes Giardia, Cryptosporidium, E. coli, Salmonella and Cholera.

Hollow Fiber Advantage: Hundreds of tiny, hollow fibers enable the microfilter to filter water faster than traditional filter media. Pure Platy experience: The Platy 2.0L Bottle is taste-free, as well as BPA-free, BPS-free, and phthalate-free. Complete Kit: Easily configure the system to your needs with the included 2.0L flexible water bottle and adapters* for maximum versatility and adaptability. 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. If you’re looking at lightweight, robust and non-plastic tasting water carriers then I’d certainly recommend Platypus. They design their products with a double layer film which means you don’t have that plasticy taste and they are also durable and they have a lifetime warranty on all their products.Its 0.1-micron microfilter allows you to confidently gulp down any water you encounter on a long trail (though the murky cow troughs in New Mexico on the CDT did have our tester filtering twice), and the high flow rate means you’re not wasting a bunch of energy just to get a sip in. The wide mouth of the flexible flask allows it to fill up in just a couple of scoops, and you can clean the filter by simply swishing water around in the flask. 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. I’ve been using water filters since May 2019, when I did a 2-month hike using one, since then I’ve tried and tested a few different filter systems and bottles and I can 100% say I’ve not been ill from drinking filtered water.
