Your cart is empty.The minimalist GravityWorks 2.0L Bottle Kit system is both ultralight and ultracompact, thanks to a simple adapter that easily connects the pump-free water filter system directly to a water bottle or hydration reservoir, conveniently filtering water for 1-4 people in the backcountry. Bottle Kit: Minimalist setup uses a Universal Bottle Adapter to connect the system directly to an existing water bottle or reservoir*. No pumping: Just fill the dirty reservoir, hang it, and let gravity do the hard work. Fast: Filters up to 1.5 liters per minute; filter lifetime up to 1,500 liters of water. Effective: Meets all EPA & NSF guidelines for the removal of 99.9999% of bacteria and 99.9% of protozoa**. Ultralight & Ultracompact: System can weigh as little as 6.6 oz. (187 g) and stows smaller than most 1L bottles. Field-cleanable: Microfilter can be easily backflushed in 4 seconds to maintain filter performance. Hollow Fiber Advantage: Hundreds of tiny, hollow fibers, enable the microfilter to filter water faster than traditional filter media. Easy collecting & dispensing: Collecting water is easy—simply open the top, scoop water, and close; control delivery of filtered water with hose shutoff clamp. Comes with: 2.0L Dirty reservoir, Hollow Fiber microfilter, Universal Bottle Adapter, hoses, storage sack. *Adapter interfaces with all Platypus bottles and most from MSR, Nalgene, Klean Kanteen, CamelBak and many more (these trademarks are not owned by Cascade Designs, Inc.). **This includes Giardia, Cryptosporidium, E. coli, Salmonella and Cholera.

This unit works so great. Fill the dirty back, hang it on a tree, and open the valve. I wish I had got this unit sooner. It is so easy to use and is very effiecient. I love using it! Get one, change your filtering! 🙂

Perfect for solo camping or for up to maybe three people with repeated fills, this filter packs up small and flexible in its included pouch, and the flow rate is good, filtering your water quickly by gravity. I love that I can use it waterside, or stick the detachable collapsible water bladder in a pocket, hike to the water source to fill up, then throw it over my shoulder by the integrated strap to filter water back at camp. The filter unit just attaches inline to the hoses, and looks to me like a standard Sawyer or Miniwell cartridge, so replacements will be cheap and easy to find if you can't re-order from Platypus. The adapters allow you to full different size bottles, from narrow-necked disposable soda bottles, to Sigg insulated stainless steel, and Nalgene or cycling water bottles, or into a clean water bladder.Cleaning is a breeze, and its easy to backwash the filter when you get home.This filter is perfect: light, easy, flexible, affordable, with the confidence of safe water available on the go to lighten your pack.

This is my second Platypus filter I have purchased. Ended up using this exclusively on a backpacking trip with 6 others. They had their own filters but this one was the most convenient. Just fill it up and watch it drain. Have used in various water sources. Doesn't remove tastes or some of the color but I have never gotten ill off the water that came through it.

Easy to assemble and (almost) impossible to get it wrong. I like the fact that the instructions are replicated within the travel case. Much faster flow through than I expected.

Works perfectly. Great water flow and easy to clean and put away.Will look into getting a larger dirty water bag as the 2L is great for 2-3 people.

Easy to use and very fast. I let very silty water from the Little Missouri River in ND sit overnight and then filtered it without any problem. Worked great adapting to varies sizes if water and Gatorade bottles so I don't miss the extra clean bladder of the complete kit. I've never owned a pump type filter and see no reason to try one now that I have this gravity type. Anything I filtered tasted fine. Great system.

ich hatte bisher das 4l modell und war total zufrieden damit. leider habe ich den filter zerstört, indem ich mal ein zu aggressives putzmittel zum desinfizieren verwendet habe. das hat den filter aufgelöst. war aber mein fehler, weil ich da einfach ordentlich putzmittel reingekippt habe und die anweisung der firma (2 tropfen chlor oder so auf einen liter wasser) ignoriert habe... meine rezension bezieht sich also auf platypus filter generell und nicht auf dieses modell hier. das hier kostet 99 euro. nur fehlt der beutel, in den das wasser hineinfliessen kann. fuer 109 euro bekommt man wo anders noch den 2. wasserbeutel dazu. deswegen schickte ich das produkt wieder zurück. hatte übersehen, dass der 2. beutel fehlt. der bottle kit eignet sich also für alle, die schon ein wasseraufbewahrungssystem haben. wenn man beide beutel hat, kann man 4 l wasser mit sich mitführen. 2 liter filtern und im sauberwasserbeutel aufbewahren und 2 liter im schmutzbeutel lassen. an den schlauch vom sauberwasserbeutel hatte ich damals ein bei decathlon gekauftes mundstück zum trinken angeschlossen, und konnte so beim wandern immer trinken, ohne den rucksack runter zu tun um die wasserflasche rauszuholen. habe auch einen uv licht wasserdesinfizierstab, finde aber den gravity filter viel besser, weil man 1. keine batterien braucht und 2. damit im notfall auch trübes flusswasser sauber filtern kann. (war mal in peru im dschungel und da gabs nur flusswasser zu trinken. seither ist mir das wichtig.)
