Why We Like The GravityWorks 2.0L Filter System

Your hand-pump water filter looks slow and inefficient in comparison with the Platypus GravityWorks 2.0L Filter System. This gravity-powered water filtration system is ultralight, easy to pack, and fast. Just collect dirty water in one reservoir, hang the system, and in just a few minutes the second reservoir will be filled with two liters of clean, drinkable water.

Awesome Water Filtration Solution

This is a great easy to use filter. Coming from the pump filter world, the gravity flow filter is an awesome upgrade. Light weigh is a plus.

I have the 4 L

I have the 4 L and it worked very well even in the BWCAW where there is often fine particulate in the water that clogs pump type filters and accelerates the need to change filters. I like the gravity feed because there are no moving parts/o-rings that might need replacing. I also like the fact that the 4 L unfiltered water reservoir is enough to put out a small campfire. I haven’t tried it but the unfiltered reservoir can also be filled, set in the sun and a few hours later hung in a tree and you can have a semi warm “shower”. The flow did slow enough to be noticeable over the course of a week of use so I’d give it 4.5/stars (not an option in the review). I purchased the 2 liter as a gift for a friend.

Purchased this for a four

Purchased this for a four day backpacking trip in the Porcupine Mountains, and it worked great. Filling the dirty bag was a cinch and clean water filtered through quickly.

Failed, no water in the backcountry.

Let me start by saying I love Cascade Design stuff. I live in the NW and have been steeped in these brands for years. I have Platypus 1 liter bottles that are probably celebrating double digit birthdays. I have always been a water pump person but was sold on the convivence of the GravityWorks system last year by a friend on a trip. I bought one and used it twice, once on a 6 day kayak trip and once on an over night backpack. Both times I followed the instructions and backflushed it. Last week we had a 7 day canoe trip on Diablo Lake and Lake Ross in the North Cascades and the filter would not pass a drop of water. I had the instructions in it and we did what we could but no luck. We ended up boiling water for two days until two trail angels named Al and Elyse gave us their spare filter. I want to love this filter, but it is junk in my book.

Just fill the bag and hang it, easiest system ever. Filtered water from stagnant puddles on the mountain with no problems.

So Far So Good!

Familiarity:
I've used it several times

So far so good! Having only ever used a pump filter, it is so nice to fill up the dirty bag and let gravity do the work. Easy to set up and doesn't take long at all to have fresh clean water.

One of the best filter systems

Inspired to buy this after pump filter not ideal when source was a trickle. Used it on Colorado Trail and in Big Bend and saved time compared to other systems.
