Rated 4 out of 5 by from Good addition to the gravityworks This is a nice addition to the already great gravityworks filter. It is probably about 2.5 inches long and only weighs a little over 1oz. Note that it does slow down the filter. After adding this mine takes a little more than twice as long to filter water. Even with the lower throughput this is the fastest and easiest filter I have ever used. I carry the carbon element along with the filter but only use it if I am filtering nasty water that wouldn't taste good on its own. It is very easy to attach in line with the filter so I can choose when I need to use it and attach or remove it without any trouble.

Rated 5 out of 5 by from Excellent results Purchased 3 months and have taken on two backpacks. Second one was into a remote area of Florida with no moving water, only swamp ponds with a lot of algae, scum and guppies, etc. The system with the carbon produced almost perfect drinkable water. The only concern was a light brown still in the very brown tea-like pond water. It has been 3 weeks since that adventure and neither of us were sick or any problems. Gotta love the platypus filtration system as it has performed flawlessly.

Rated 5 out of 5 by from Tastless water This is a perfect addition to the gravity water filtration system. The carbon element removed all the smell and taster from the water. Without it, I'm not sure my kids would have drank as much water as they did while floating the Shenandoah River. Overall...an inexpensive addition to enhance any trip.

Rated 3 out of 5 by from A very simple hack If you want to run a carbon filter in line with your filtration system, then any one of these filters should do the job for you. I came up with a pretty simple, inexpensive substitute that requires no building and is also manufactured to tight performance standards. We have a few Brita water filters left over from an old pitcher. With a light weight 12-16 inch long cooking bag I simply secured the top of the bag around the water filter, wound a second rubber band below the inflow of the brita filter, and then place the open bottom of the bag into the bladder I am filling. The filters cost a fraction of the inlines but you do need to have some spare bags because you need to backflush the system fairly frequently, and each time you do this, you need to take off the top band to access the nipple. Yes, kind of a pain, but my concern with all of these filters is their longevity. It isn't based on volume of water passing through, it is based on how much toxic material is removed from the water. This means if you are drawing from a pristine creek you should be good to go for multiple trips. If you are drawing from any water source downstream from a road, I wouldn't trust one of these filters past one trip unless it's a quick overnighter.

Rated 4 out of 5 by from Can be important part of making water drinkable Bought this to augment my Sawyer Squeeze based filtration system. I also have the MSR Silt Filter as an element. I hook these up with Sawyer's adapter/connectors kit parts to be able to snap together a gravity filtration system that can address the water situation found. No doubt about the Carbon Element being effective in improving taste and smell, which are important even if baddies are removed. NOTE the impact on a gravity filtering of 1L: Sawyer Squeeze: about 2 minutes per liter; Silt Pre-filter plus Squeeze: about 7 minutes per liter; All three filters: about 20 minutes per liter. Also have the SteriPEN Classic with Fits-All pre-filter: maybe 2 or 3 minutes total. ... then, in either case on the trail, hard boil that water when possible, too. The SteriPEN won't make that water "bottled potable" without also running through a Carbon Filter, but does do the job of making it safe - little wonder more are using this method on the trail despite it's being a battery powered gadget. Bottom line is that the Carbon Filter can be an important part of making water drinkable, whether part of a gravity filtration system or post-sterilizing water quality improvement system... but it does restrict flow rates, so don't be in a hurry. I think filtered water is great for making coffee, tea, cocoa, instant or freeze dried this and that, etc., especially since you're likely to boil anyway for that extra measure of safety - and you really want these to taste good, so this can come in handy.

Could I cut my drinking tube to my Platy hoser and put this in between and use like a Sawyer? It is a little cheaper this way

This is not a filter. This removes flavors and odors from water to improve the taste, but it does not remove bacteria, viruses, or protozoa. We do not recommend using this as a filter with your reservoir.
