About this deal

Each day I would find the nearest water sources on the map, maybe a stream, spring or brook and few treat stops (pubs and cafes) where I could get tap water! 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. The loop by the lid makes it easy to fill without a fear of letting go and losing your reservoir downstream and it’s handy to use to hold it too.

Effective: Each 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. As someone that hikes in the Peak District this is something I’ve got used to! But I appreciate it’s not for everyone. In the instance of being dehydrated or drinking peaty water I know which option I’d choose!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. The LifeStraw Squeeze Filter also performed well in testing, though not as much as others on our list. It’s modular, so while it has the filter incorporated inside the squeeze pouch, you can also move it to the outside (and swap out the cap) if filling bottles or not drinking directly from the filter. Both are a great price. Ultralight & Ultracompact: System can weigh as little as 6.3 oz. (180 g) and stows smaller than most 1L bottles (depends on configuration).

It’s not flawless, though. First, it isn’t as versatile as the Squeeze in that it won’t fit over standard water bottle mouths (this isn’t an issue if you plan to just use the included flask). Second, it tends to clog a little faster in filthy water than other filters, including the Squeeze. I’m afraid the filter is good but it doesn’t turn dirty (muddy/peaty) water into clean water by sight! Then depending on where the next water source was I’d fill the 1-litre reservoir and maybe my 500 ml one too, if it was a distance to hike. 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?

Compatibility

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

If you’ve drank filtered peaty water depending on the colour of the water you can notice a slight soil taste, but it’s not something I’ve ever been bothered about, the darker the colour the stronger the taste of peat you’ll notice. Group-ready: 8 liter (4.0L filtered + 4.0L unfiltered) total capacity easily supplies water for groups. 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. The filter system is so easy to use and I loved how it was versatile so you could switch to how you wanted/needed to use it at a particular time. Pure Platy experience: The Platy 2.0L Bottle is taste-free, as well as BPA-free, BPS-free, and phthalate-free.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. MSR’s setup is simple, even if you do need ample space to get the dirty reservoir at least 6 feet above the clean water receptacle (fairly common for gravity water filters). The speedy flow rate is ideal, and the bottle adapter fits a range of sizes to allow the filling of separate water bottles or a larger container with the entire 10 liters. These filters use gravity to pull water from a dirty bag, through a filter, and into a clean bag or directly into your mouth. These are often the easiest filters to use as you simply hook it up to a tree branch or tent and wait. These are usually heavier and take some time to set up, so aren’t the best options for fast and light missions. They tend to work best for large groups or to keep around a base camp. Easy collecting & dispensing: Collecting water is easy—simply open the top, scoop water, and close; control delivery of filtered water with hose shutoff clamp. Hollow Fiber Advantage: Hundreds of tiny hollow fibers enable the microfilter to filter water faster than traditional filter media.
