Platypus GravityWorks High-Capacity Water Filter System for Group Camping and Emergency Preparedness

Product Information

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. 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. 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. 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. Pure Platy experience: The Platy 2.0L Bottle is taste-free, as well as BPA-free, BPS-free, and phthalate-free.

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. The filter has a grey screw lid at both ends, one covering the filter (known as the dirty end) and one that you pour or drink the water from (the clean end). Yes, there’s not really much you need to do other than fill the reservoir, screw the filter on and turn upside-down, gravity does the rest for you!

No pumping: Just fill the dirty reservoir, hang it, and let gravity do the hard work—yep, filtering water can be as easy as fill, hang, relax. 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.

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.

Taste-Free Hydration

They work great for larger groups or when you want to filter a lot of water all at once. They’re also quite light, given their speed and ease of use. 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! 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. 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!

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*. 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. Ultralight & Ultracompact: System can weigh as little as 6.3 oz. (180 g) and stows smaller than most 1L bottles (depends on configuration).

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**. 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*. Group-ready: 8 liter (4.0L filtered + 4.0L unfiltered) total capacity easily supplies water for groups.

The personal Peak Series filter worked extremely well and had a good flow rate. After 20+ years of LifeStraw being on market, it was nice to finally see a big upgrade in materials and design. Group-ready: 8 or 12 liter (4.0L/6.0L filtered + 4.0L/6.0L unfiltered) total capacity easily supplies water for groups. 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! To justify taking anything on an extended thru-hike it needs to be dependable, lightweight, and durable enough to last for months of torture. Today, you usually see one of two popular filters being used by long-distance hikers going the length of trails like the PCT and AT: the Sawyer Squeeze or the Katadyn BeFree. 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.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.
