The Platypus GravityWorks 4.0L Filter System is a water filter for the whole group. In 2.5 minutes, you've got 4L of water, ready to drink, cook with, clean a little. Your basecamp group will love getting put on water duty, because all they have to do is fill up the dirty bag with water from the source, then hang it higher than the clean bag, connecting the filter between the two. Then walk away, completing another task as you wait. Simple, easy, more time to enjoy your surroundings.

Rated 5 out of 5 by from Gravity always wins! I've used pumps, drops, tablets, boiling, praying, regretting... This is by far the quickest, easiest, best-est filter system I have ever owned.

Rated 5 out of 5 by from Works fast! I bought this for a weekend hike on the AT a couple weeks ago. Previously, I had an old pump filter. This is so much more convenient; just hang it up and make camp while your water is filtered. I really enjoyed having filtered water on tap afterward too.

Rated 3 out of 5 by from Filter element durability issues. I use this system in the back country of California and southern Oregon. The reservoir bags are tough, but the filter element is not. I have had to replace the element nearly every time I've used this system due to element failure.

Rated 4 out of 5 by from Great filter. 4L in 4 minutes! But...impossible to close. This filter is amazing. 4L in about 4 minutes. It works very well in Montana. We've had it for years and the filter is still going strong. We've saved a lot of hikers who were spent from pumping or their filters just failed completely. So fast and easy - as long as you quickly backflush each time. Unfortunately, there is a deal breaker and here it is: the "zipper" closure on the dirty bag is impossible to get closed. I can't even do it. My husband has to do it and although he is strong, it's very very difficult. And if you can't get it closed, there is no vacuum and the filter won't work. Isn't there a better design or some sort of slide tool that can be offered to help close the bag?

Rated 5 out of 5 by from Let gravity do the owrk for you This is the second Platypus filter I've purchased. The previous one has served me well on several campouts where it supported 10 or so campers. It makes it easy to keep the camp supplied with water from almost any source. I picked up the second one as a backup and also to filter twice as much water when supporting a large group.

Rated 5 out of 5 by from Good water as easy as it gets I saw a kayak guide use one of these and it looked like a lot less effort than my pump type filter. It filters 4 liters quickly with no effort compared to 15 minutes or so of hand pumping to get a liter with my previous method. Excellent filter.

Rated 5 out of 5 by from Easiest Filtration Ever I used this for a week-long camping trip in the Boundary Waters Canoe Area Wilderness last fall. It worked great. There were 3 of us, so we went through a lot of water. We must have filtered at least 40 gallons over the course of the trip. The large 4-liter design made it easy to get enough water to fill our bottles, cook and do dishes. It only took about 10 minutes to filter the entire bag. I've used pump filters before this and will never go back to them. We used a designated "dirty" Nalgene to fill the bag which made that a snap. I'd seen some reviews about the grommets pulling out on the dirty bag, so I stuffed it in a mesh bag that originally held 10# of onions for hanging. Problem solved. I highly recommend this product.

Rated 5 out of 5 by from Sweet, cool, clean, water Very good product. Works good, packs up small, and add the charcoal filter and it's the bomb. Very easy to set up and use. Can have water before I'm done hanging my warbonnet

What happens to filter if it freezes in September in higher altitudes

Asked by: Llama packer
Hiya Llama packer, thanks for your question! You should not use a water filter after it has been exposed to freezing water. You should consider using tablets instead, like MSR Aquatabs or Katadyn Micropur MP1 Purification Tablets. Check them out here: MSR Aquatabs Water Purification Tablets https://www.moosejaw.com/moosejaw/shop/product_MSR-Aquatabs-Water-Purification-Tablets_10334660_10208_10000001_-1_ Katadyn Micropur MP1 Purification Tablets https://www.moosejaw.com/moosejaw/shop/product_Katadyn-Micropur-MP1-Purification-Tablets_10009076_10208_10000001_-1_

Does this system filter to drinkable water standards? The video says cooking/cleaning water. Would the Platypus Gravityworks Carbon Filter Element be a benefit or does the included filter perform carbon filtering? Thanks

Asked by: Tincup
Hey there Tincup, good questions! Yes... in addition to providing water for cooking and washing, this system provides clean drinking water. You can use the Carbon Filter Element along with with the GravityWorks filter to improve the taste or odor but its not a necessity. (Some people can't tell the difference in taste so it's just a preference.) Since the carbon filter will not filter out the bad stuff on its own, you'll want to use the carbon filter after the water is already filtered with the regular filter. It is an accessory and not meant to be used as a substitute for the regular filter. (Wow, I just said filter A LOT.) Hope this helps!
