We want to make extra-sure you realize that you've added a special order item to your cart. These items take a little longer to get to you because we have to order from the manufacturer first. The "Est. Ship Date" is the date we expect items to leave our warehouse... so add your chosen shipping speed to see when it will show up at your door.

Rated 5 out of 5 by from Love it. Wading in to Love it. Wading in to ice cold lake superior to pump water with my old filter was a pain. Now I just scoop a bag full and let gravity do the work.

Rated 5 out of 5 by from Tastes's Great I have a few different water filter systems, but this is the most straightforward, lightest, on-the-go water filtration system in my arsenal. It packs easily and does exactly what it states in the description. Won't go into the great beyond without it.

Rated 5 out of 5 by from Easy to use system This is the second filtration system we have owned and we won't ever look for another after using the Platypus. It's very easy to use on the trail and filters the entire bag in about 15 minutes. We've used our system for 6 years now on backpacking trips with our 4 children. Our now grown boys requested systems of their own since the Platypus gets the job done quickly and easily.

Rated 5 out of 5 by from Highly Recommended, Easy to Use After having borrowed a friend's GravityWorks, I decided to buy my own. The up-front cost (vs tablets, or drops) had made me hold off for years. Absolutely no regrest with the purchase. So easy to pack and set up. It does the job so quickly that instead of struggling to get water quick enough, our campsite and canoe rides are always flush!

Rated 5 out of 5 by from Awesome set up for camping. Awesome set up for camping. Great time saver. Works well. Just fill up and in 5 minutes you have water, a lot more convenient then pumping water.

Rated 5 out of 5 by from Amazing filters I took 6 college students on a 5-day backpacking trip and we used 2 of the 4-liter gravity filters. They worked great!!!! We filtered so much water and the filters never clogged: I did backflush them a couple of times. These filters sure made the trip easier.

Rated 5 out of 5 by from This is a fantastic filter! I've had a 4L Gravity Works system since 2014. I bought a replacement filter thinking I'd need to replace it at some point. I haven't needed to replace it. The original is still going strong. I've filtered lake water, spring water, mountain stream water. It works fast and with a back flush you're ready to go again. It filters quickly and effortlessly (unlike my old pump filter which was a total pain.) Plus with some serious capacity, you can support your group with one filter and have enough water to get a lot done without a lot of work. I highly recommend the Gravity Works filter.

I tested the filter out by taking tap water and mixing in soil from our herb box. The filtered water came out yellow, is that normal?

Asked by: Kim Possible
Hi Kim Possible, thanks for the question! I would say the yellow is definitely from the soil, this microfilter was made to filter water not mud, the excess soil will cause problems for this filter. I would backflush your filter and try another test from a water source (river, pond, creek, etc.), without getting any bottom material or mud. I hope this helps!

Why, are several reviews shown as being posted on msrgear?

Asked by: Jim P
Hi Jim P, thanks for the question! Platypus and MSR and both under the Cascade Designs company umbrella, msrgear is simply where these reviews were originally posted to give you a better idea of the product. I hope this helps!

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!
