Rated 5 out of 5 by from Works great with my 2.0L system as welleen I have the 2.0L filter system;but I wanted to get the 4.0L for my family camp outs. I love that I can easily change bettween the 2.0L and the 4.0L. How well does it work? It can filter 4L faster than you can drink it. Under 3 minutes. A group of 8 can be refilled in about ten minutes well you enjoy your quick snackbreak. Easy to clean and back flush. I give it 24 hours to dry, before I put it back for storage. Great taste too. Beauty!

Rated 5 out of 5 by from Quick and easy water filter system! I'm an amateur backpacker and avid outdoor enthusiast. Had this on 1 backpacking trip on the Shenandoah National Park (~3300ft elevation) so far on the Nicholson/Corbin Cabin trail. I've used it on a local Hughes river running through and walked it back to camp. Filtered 4 liters of water very quickly (~5 minutes) and very easy to use when hung. I'm so glad I got this because I was a person who use to always boil water or carried 3 L in with my camelbak; but this will certainly extend my trips in the future! The plastic bags are of high quality and everything seems durable. I've kept the clean components in a plastic baggie so they stay nice and dry. I would highly recommend this product and look forward to using it more in the future!

Rated 5 out of 5 by from I've never considered going back to my pump. I've used my 4.0 L Gravity Works guiding in the Sierras for two summers now. I love that I can hang the system and get back to business. I'm ordering two more for facilitating larger groups in a base camp setting. The learning curve for me was in keeping water in the filter and line between uses by engaging the little pinch lock before the last of the water passed through the filter. This seems to speed up the next filtering process by keeping air out of the filaments. The bags hold enough water to back flush and still have 4 L left. The clear plastic allows the operator to get an idea how dirty the water is and to adjust back flushing accordingly. Slower filtration means either more back flushing or air in the lines. Great for mosquito infested lakes and streams too. Just haul the Gravity Works back to the tent and watch it work for you. Only drawback is that the system can't freeze.

Rated 4 out of 5 by from you'll never use a pump filter again this filter is great. yeah after a lot of uses it slows down. i wasnt sure how the system would hold up but i havent had any problems with durability as far as the plastic sleeves go. the only knock i have on the produce is that the "dirty" water bag has like a ziplock seal that does not seal. i talked to them and they said something about getting it wet and really working to get it closed but i cannot. not a big deal since i usually backpack where there are lots of water sources. but i could see how it could be a problem.

Rated 2 out of 5 by from Love the system but hate the filter. The first time I used this filter system it worked great. The water I was filtering had a yellow tent to it while in the dirty bag but came out clear and delicious after filtering. I tried back flushing the filter as directed but water would not flow through the filter backwards. I chalked it up to being a new tight element. The second time I used it; the water was moving very slow, so I tried back flushing again but still no flow. I gave the clean bag a little squeeze and water started to back flow. After that I got about three uses out of the filter before it stopped filtering. It filtered roughly 18 liters before the filter died. Luckily I found a home store that was selling a very large but usable filter and once again I have clean water. I may have just got an odd ball bad filter. I really like the quality of the bags though.

Rated 5 out of 5 by from The best water filtration system if you travel in large groups. I love this system, definitely an upgrade from my old MSR hand pump filter. I got this system because I tend to travel in a large groups when hiking. The 4.0L system allows me to provide enough water for the whole group. I also like the fact that I can fill my balder and still carry an extra 4L of water, just in case I have to travel between two watering points that are fare apart. I highly recommend this product.

Rated 5 out of 5 by from Fantastic filter system 4 liters of clean water in about 4 minutes! While everyone else is sitting around trying to figure out if their Steripen is going to work today or turning the little crank on their pump filter, you will be heating water for coffee. Backflushing is straightforward. It would be nice if there was a valve on opening of the Clean bag so you don't take a shower. Great system.

Rated 5 out of 5 by from Best gravity filter out there! After days and days of research and exploring DYI options for a gravity filter I decided the Platypus Gravityworks was the best backpacking option for myself, girlfriend, and two dogs! The whole system is very simple and easy to use, backflush is a breeze. Awesome product and no PUMPING. Sit back, stir the fire, and let gravity filter water for the group.,,

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.

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!
