Rated 5 out of 5 by from Hassle free filtering The Gravity works is light weight, packs up small, and is so easy to use! It’s so nice to just fill it, hang it, and let it do the work! I’ve had pump style filters which work well but it’s a pain to have to sit by your water source pumping water while you could be doing other things like setting up camp or getting a meal ready. I’ve found it is important to backwash the filter regularly in order to keep the flow rate consistent but otherwise it’s hassle free filtering. Love this water filter!

Rated 1 out of 5 by from Missing pieces Not happy. The product I purchased is missing a critical piece. I purchased the filter in shop far away from my home so I can’t easily return it. I’m just great full I checked the unit before taking on a hike.

Rated 4 out of 5 by from Great filter, easy to use! Works fantastic. Packs up small, doesn't weigh much, and is pretty easy to use. I had to buy the bottle adaptor separately to get it to thread straight on to Sea to Summit water reservoir. Only complaint so far is that backflushing is a little complicated at home in the sink, I wish the instructions were a little clearer on how to do this for longer-term storage.

Rated 5 out of 5 by from Great Remote Aid Station For Trail Races Water Filtering System We have trail running events that take us into remote locations where we either need to hike in water or filter it. We've tried the pump filters and it was faster to carry in the water rather than pump our arms for days on end. Our first experience was great, filtering 10 gallons of water with the 6.0-liter system at an aid station in 25 minutes. We'll be buying more for future use.

Rated 2 out of 5 by from Mixed feelings The concept of the filter is great. Relatively easy to use and gravity does most of the work. It also is lightweight and easy to store/pack. However, the disappointing part is the dirty bag (which is similar to a zip-lock). No matter what you do, you can't really get it to close! If you do, it will reopen in a few seconds. Having the dirty bag open has two downside, first you get air in the system and second you start losing some of the water. I'm not sure if mine is defective or if this a problem with the design.

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.

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!

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!
