Perfect for base camping or larger group backpacking trips, the Platypus GravityWorks 4.0L Filter System utilizes innovative Hollow Fiber technology to offer pump-free water filtration.

Description

The Platypus GravityWorks 4.0L Filter System utilizes innovative Hollow Fiber technology to offer pump-free water filtration. Perfect for base camping or larger group backpacking trips, the GravityWorks 4.0L Filter System includes a 4.0L Dirty reservoir and 4.0L Clean reservoir.

The groundbreaking Hollow Fiber Technology used by the GravityWorks 4.0L Filter System enables it to efficiently and effectively filter 4 liters of water in just 2.3 minutes! Simply fill the 4.0L reservoir marked "Dirty," suspend it from a branch using the strong clip webbing, and allow gravity to filter the water into the "Clean" BPA-free 4.0L reservoir. The "Clean" reservoir disconnects for easy dispensing.

The 0.2 Micron cartridge exceeds EPA guidelines and is completely field maintainable and long lasting, effectively filtering up to 1,500 liters of water (depending on water quality) before needing replaced! The GravityWorks 4.0L Filter System can be backflushed in seconds to clear the filter of debris and the streamlined, lightweight filter housing is durable and saves on weight and space.

NOTE: The Platypus GravityWorks 4.0L Filter System meets all EPA and NSF guidelines for the removal of protozoa, bacteria and particulates. It is NOT effective against viruses.

  • High-capacity storage and filtration
  • 4L Dirty reservoir and 4L Clean reservoir
  • SlimeGuard antimicrobial treated reservoirs
  • Clean reservoir disconnects for easy dispensing
  • Clip webbing for easy hanging
  • Bold graphics for quick identification
  • Corner mounted valve for better packing

    Performed as advertised. Very fast, easy to use, and very convenient system.

    Filtration speed. Nice to set up away from the water source and let the system do its thing.

    Love It!

    Likes

    I love how fast it filters a large volume of water. I just took it on a 3 night / 32 mile backpacking trip. If you camp by a water source, you can just hang it in a tree, leave the hose on, and you essentially have a kitchen sink. I'm trying to trim pack weight, but this is staying. It's well worth the few extra ounces.

    Dislikes

    A little heavier and bulkier than some filters, but it more than makes up for it in convenience.

    A simple and easy water filtration system that packs down into a very manageable size. Perfect for kayak camping!

    Loved how quickly we could get a gallon of water! Lifesaver backpacking with a family of 4 in the summer! Easy to use.

    Dislikes

    A little challenging to dry the clean water pouch as there is no large opening

    Cleans water quickly and efficiently

    Likes

    Filters water fast. Large opening on dirty water bag makes filling quick and easy. A great system overall.

    Dislikes

    Don't care much for the small opening on the clean water bag, makes it harder to clean/dry.

    Works as described but I haven't really used it in real world yet. I would expect it would perform as what its expected to do. I was debating between this 4.0 liter VS the 2.0 liter but I read one review that there's not much difference in size so I went with the 4.0 liter version. I can easily stuff this in my 58L Exos.

    Does your group have to drink?

    Likes

    Easiest and most reliable option to process lots of water in the backcountry. Don’t bother with the 2L. Just get the 4L and fill it less if you want as it’s already pretty small.

    Simple, fast filtration

    Likes

    Filters large quantities for 2+ hikers during breaks or at base camp. I have switched to this from using the Sawyer Squeeze because this is zero effort. I drink tons of water and was tired of squeezing. Worth the weight in my opinion especially when split between multiple hikers.

    Dislikes

    I have a hard time zipping the "dirty" bag at the top, but I have weak hands.

    Outstanding for program use

    Likes

    I bought this for a wilderness backpacking program and I love it! It filters quickly and adequately for a group of 10-13 people.

    Dislikes

    Price is a little high, but it is excellent.

    Easy and Quick

    Likes

    Quick to set up - just a rope tied between two trees, or another type of holding system and you are ready to go. Really fast to filter water - once you fill your dirty bag and let a little through, just raise the clean bag to both backflush and get the air bubbles out of the line and the water will flow through really quick. Great for base camp or large amount of water quickly.

    Dislikes

    The dirty bag top is a bit tricky to close.
