Most Helpful Positive Review easy filtration system
I love this filtration system! It's user friendly and faster than pump styles. The amount of water you get from the bag is enough to do dishes and wash up a little plus put water in whatever container you've chosen

  • clogs
Best Used for:
  • Backpacking

2 bag system is the way to go

by Robert, Verified Owner from NC, United States Written on September 5, 2021
Used the Platypus Gravity 2 bag system this weekend, and it was great. So convenient. Having instant access to clean water without having to pump or wait drip drip drip for the gravity feed is a game changer. Can easily support 6 to 8 ppl.
Pros:
  • Light weight
  • Easy to use
  • Large capacity
  • Instant water
Cons:
  • None
Best Used for:
  • Backpacking
  • canoe camping
Would recommend: Yes

Reliable and Quick

by Dani, from DC, United States Written on October 10, 2020
This is the perfect water filter for small group backpacking trips. This filtered enough water for our group of 4 in under 10 minutes, hangs easily at your campsite for future use, and is easy to back flush (although rarely necessary).
Would recommend: Yes

Platypus water filtration

by Jeb, from CO, United States Written on January 29, 2019
I tried out my Platypus recently in Colorado back country and it works well. Sets up easy and water was ready in minutes. Back flushing the filter is just as easy. Also it packs up into a nice small roll. Happy with the quality.
Pros:
  • Works well, easy to use
Cons:
  • 2 holes to hang look weak
Best Used for:
  • 2 people back country hiking
Would recommend: Yes

Finally ditching the pump!

by mc, from UT, United States Written on August 7, 2018
We brought 2 of these for 7 people and 3 days/2 nights. The clearly marked dirty/clean bags keep exhausted filterers from messing up (and the fact you can't fill the clean bag from the top). Backflushing is easy and we were able to filter 20+ litres of water in about half an hour without getting a swole pumping arm. Lightweight and easy to use, I'm so excited to ditch the pump.
Pros:
  • weight, speed, simplicity
Cons:
  • None
Best Used for:
  • Backpacking, camping
Would recommend: Yes

  • QUALITY
Cons:
  • None

An almost perfect system that’s light weight, and easy for anyone to use!

by Silas H., Written on July 17, 2017
This is a great system (I’d say it’s 99% perfect)! Almost anyone can use it with little instruction, and it’s a quality filter that’s light weight and compact. The only thing that would make it absolutely perfect would be a small removable screen to catch the larger pieces of debris that inevitably will get into the dirty bag before they get to the main filter. That being said, I show this off and brag to everyone that asks about it (and some that don’t)!

Easy to use!

by Christopher P., Written on June 29, 2016
This water filtration system is the easiest I have ever used. It is remarkably fast, filtering the full capacity in less than three minutes. The only downside is the grommet holes in the reservoirs; they are very weak and after only one camping trip show promise of tear-out. (This won't affect the integrity of the system though, just the ability to hang it.)

Platypus 4.0L gravity feed replacement bags

by Troy J., Written on May 25, 2016
I have not used the bags yet, but they are of the usual good Platypus quality. Note: I did not receive a cap for the clean bag with purchase, hence knocked off 1 star.
Would recommend: Yes
