Rated 3 out of 5 by from Does not come with adapters included in 2L kit Was surprised that the 4L kit doesn't include adapters for Nalgene bottles and MSR bladders. Must be purchased separately, although they are included in the 2L kit.

Rated 5 out of 5 by from Simple It does the job well. filters large amount of water without much effort. Make sure to follow the instructions and back flush for best results. Plastic is strong and will take a lot of abuse.

Rated 5 out of 5 by from Awesome product! Works flawlessly and moves water quickly through the filter into the clean bladder or anything else you want to fill. This system processes a lot of water in a snap.

Rated 5 out of 5 by from Easy to use, and is great for groups I used my friends filter during a 3 day hiking trip. We had 10 guys in the group and this filter was being used pretty much non-stop. It worked perfectly, was easy, and filters large amounts of water relatively quickly.

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.

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!
