Product Description

The Platypus GravityWorks 2.0L Complete Water Filter Kit for camping, backpacking, and emergency preparedness is a versatile, adaptable water filter solution, compatible with a variety of hydration vessels, including hydration bladders and water bottles from MSR, Nalgene, Klean Kanteen, Hydroflask, Camelback, and more. Ultralight (weighs as little as 6.6 ounces in minimalist configuration), and packable to the size of a 1-liter bottle, it’s ideal for filtering water for 1-4 people while hiking, camping, or trekking. The replaceable hollow-fiber microfilter cartridge filters up to 1,500 gallons of water, and meets EPA and NSF guidelines for removal of 99.9999% of bacteria and 99.9% of protozoa, including giardia, cryptosporidium, E. coli, salmonella, and cholera. The water filtration system is easy to use almost anywhere, by scooping water from a lake, river, stream into the 2.0-liter dirty water reservoir, and suspending above a bottle or other clean water reservoir. Water flows through the walls of the bundled fibers at rate of 1.5 liters/minute, leaving impurities behind, without the use of pumps, batteries, moving parts, or chemicals. It’s also easy to maintain in the field, backflushing in just four seconds to clean and restore performance. The Platypus GravityWorks 2.0L Complete Water Filter Kit Includes a 2-liter dirty water reservoir, 2-liter Platy bottle, hollow-fiber filter, hoses, universal bottle adapter, push/pull cap adapter, and storage bag. Made in the USA.

    Bag Defect
    I really like this filter. I used it for approximately 8 days on the A.T. and 7 days in Quetico Provincial Park in Ontario this summer. I do have one gripe about the dirty water bag which is affecting performance. Where the strap to hang the dirty water bag pulls through the bag the reinforced ring that keeps the bag from being torn pulled out, allowing the weaker fabric to stretch when it hangs. Many times I stood up holding the bag for fear it would tear and fall.

    5.0 out of 5 stars A literal life saving device.
    Reviewed in the United States on June 12, 2019
    Size: 2-LiterVerified Purchase
    I just picked up backpacking as a new hobby but have loved camping. I knew at some point we would go somewhere where I did not want to pack in all the extra water it would take to get in/out, and where we would have water at the campsite. So, after reading reviews, I got this guy.
    IT IS ULTRA FAST! Compared to my old filter, this is lightning fast. Simple to use. Quick to set up. I bought the kit for 2.0 liters, but honestly, it's so fast, I don't see why anyone would buy the larger size just because they had a couple more people. It takes less than 3 minutes to filter 2.0 liters. Then we transfer to our camelbacks and treat with iodine tablets as an extra precaution. And in another 3 minutes, we've got another 2.0 liters.
    The ONLY thing I don't like is that I haven't been able to find a way to fit the filter itself into the mesh carrying case with all the rest of the kit. I wish that the mesh case was a smidge bigger for this reason. But that's a convenience thing, not a function of the kit thing.
    We tested this on our first trip only carrying enough water to get us to the site + a smidge extra. We hiked in 90+ degree heat in Arizona, and knew we'd burn through a lot of water. We got to the site which we knew had an 8 foot deep pool of water, and got to work using this kit. The water we filtered was flowing, but had all sorts of animal life in it (fishing spiders, frogs, tadpoles, water beetles) and is visited by various wildlife such as coatimundi. It also had plenty of plant growth within the pool. So we wanted to/needed to filter the water and didn't want to rely on boiling for 5 minutes. It's been 4 days since the trip and we suffered no illness, so if the water was tainted, the filter did it's job and got it all out. We'll be taking this on all our hiking/backpacking trips either knowing we need water, or just in case we need water.

    5.0 out of 5 stars Best watler filtration system out there, stop squeezing and let gravity do the work.
    Reviewed in the United States on December 25, 2015
    Size: 2-LiterVerified Purchase
    Once you switch to a gravity filter system you will never go back to a squeeze system again. Not only is the water filtered more quickly, but you can hang this thing in camp and let it filter as you go about your business.

    If you have never used a Platypus Gravity Works system before, the photo makes it look more complicated than it is. While the carrying case and additional adapters are a nice touch, you probably wont use most of them, ever. All you need to bring with you is the dirty bag, tube and filter, and something to carry your clean water in (it doesn't have to be the clean bag shown in the photo). I usually just filter water straight into my Nalgene or plastic water bottle, but I do bring the clean bag along and use it if water sources are scarce or if I want to stock up for camp.

    Both the clean and dirty bags are very durable and the clean bag stands upright on its own when it is filled at least 1/4 of the way. Leaving additional accessories at home will allow you to shave some weight, and you can also cut some grams by removing the gray rubber ends from the filter, which serve no purpose unless you plan on mounting it to a bottle, if you are OCD about your pack weight.

    4.0 out of 5 stars Pretty fast for a gravity filter
    Reviewed in the United States on October 25, 2019
    Size: 2-LiterVerified Purchase
    This unit is pretty fast for filtering water.
    Went backpacking with 7 people and used one of these for all of our water purification. It was more than fast enough. This unit is fast enough that you could probably filter water for 50 people with it without too much effort. I mean it's really fast! When camping with just one or two people the 2l capacity is really a luxury. I just hang it from a tree or set it on a rock and it filters away with no work on my part.
    My only complaint is that it's bulky and awkward to pack: big bulky foam ends on the filter, hoses stay attached to filter, unit is just annoying to pack.
    I made a custom sized stuff sack out of waterproof rip-stop and now it's not bad, but without that it's really annoying to pack this thing.
    The 2l clean water bag is nice because it allows you to filter water ahead of time then refill the dirty bag so you are ready to filter more.

    5.0 out of 5 stars Most important part of my kit!!
    Reviewed in the United States on May 26, 2014
    Size: 2-LiterVerified Purchase
    This here is a great water system.. crazy fast filtering.. no work needed... can double as a simple filter straw.. and all packs away easy, small and light. I read reviews and watched many videos of various systems being used, talked to users, and used a few systems myself over time. The research showed me that this was the best system for my 4 person, 1 dog family and the wild backpacking we like to do. The super fast filtering of about 1.5L a minute means instant drinking water and refilling all the water bladders and canteens for the group is fast, and no pumping makes it super easy for anyone. Gravity does the work! This was pretty much the fastest filtering system, that is not crazy over priced, I could find. The amount of filtering it can do before a new filter is needed is also very nice.

    The product parts are all made very well and of quality materials. Even the tubes are very high quality. Adapters are included to fill MANY types of containers, but anything can be filled right from the tube, that is what we do. Take only the parts with you that you need. The collapsible clean water bag even comes with a pop up sports bottle like cap so it becomes a 2L water bottle when needed!

    Take along a set of purification tablets/powder (virus killing) for use if all you can find is questionable water... and you are set!!

    5.0 out of 5 stars Great water purifier
    Reviewed in Canada on April 10, 2024
    Size: 2-LiterVerified Purchase
    I have used this product on several camping trips as my sole water purifier for water from outdoor sources.
    Very easy to use. Comes with two see through bladders that are marked for clean water and dirty water. The filter removes all visible debris / mud from the water. I used water from flowing streams, lakes and the cleanest standing water I could find. The treated water always tasted clean: no odours, no odd taste, fully clear. Tasted and looked great.
    I never got sick from drinking the purified water from this. I would just drink the treated water straight; without boiling or any other purification method.
    Reversing the flow (from the clean water bladder to the dirty water bladder) visibly cleaned the filter and you could easily see the dirt backwash into the dirty water bladder.
    Packs up small and light in the fabric bag that’s included.
    After a week of use I’d wash the “dirty” bladder with dish soap and water. Store indoors in the case. Never let it freeze.
    Have used this probably three different camping trips. I’ve purchased an additional kit for my brother-in-law and another as a back up for my home for emergency use. This product is a pivotal part of my SHTF emergency preparedness plan. I rely on this heavily because I’ve tested this product while camping.
    I would definitely recommend this product.

    5.0 out of 5 stars Absolute Kaufempfehlung für Thru-Hiker!
    Reviewed in Germany on April 7, 2024
    Size: 2-LiterVerified Purchase
    Bei meinem ersten Thru-Hike hatte ich den „Squeeze“-Filter eines bekannten, namhaften Herstellers - und er hat einen guten Job gemacht.

    Allerdings fand ich es schon hart anstrengend, täglich nach ~15 Meilen (Gebirgswanderung mit Zelt und Rucksack) das Lager zu errichten und dann noch mehrere Liter Wasser für abends und den nächsten Morgen - teils im Dunkeln und bei einstelligen Temperaturen - durch den Filter zu pressen. In der Zeit hätte ich lieber schon geschlafen oder einen Gute-Nacht-Tee getrunken ;)

    Da ist dieser Filter eine wahre Evolution - und meines Erachtens jeden Euro und jedes Gramm mehr wert! Man füllt ihn, hängt ihn (bspw. an einem Baum) auf - und während man sich anderen Sachen (z. B. dem Zeltaufbau oder der Körperpflege) widmet, erledigt die Schwerkraft alles andere. Funktioniert auch nach Jahren noch einwandfrei.

    Verpackung und Versand waren auch nicht zu beanstanden.

    Insgesamt klare Kaufempfehlung - auch für Minimalisten! :)
