How does this system compare with the platypus system just offered on massdrop?

I’ve been using this filter for the entirety of my 2017 backpacking season. It did it’s job very well. Like any gravity filter, flow will slow a bit over time, and I found I have to kind of squeeze the bag a bit to get the air bubbles out now and for the flow to start. Backflowing will obviously help that a bit, but not entirely. I still trust this filter and will use it for 2018 as well. Note: if you’re hiking on mostly sub-arctic tundras and hummocky tablelands, like me, you may find it hard to find a tree to hang this from. That can be quite annoying! I’ve destroyed my arms having to hold the 2L of water over my head more than once haha. Fun times in the maritimes.

So just to confirm.... this drop does not offer the ultra .02 level purification, eh?

jgwhat1I see it as a $25 discount from Amazons pricing of the blue grey .1 micron unit. The .02 micron setup is like $240 I think. The .02 filter and faucet adapter is $130 by itself.

JromYes, seems so. Going to India/Nepal so that extra purification is vital. Found a good deal on the 4L .02 on moontrail . com if anyones interested.

I've had the 2ltr for about 6 years now. First used on a week long kayaking trip in Lake Superior Apostle Island with 3 others. It's fairly easy to use and getting water isn't difficult. Like any filter especially styles like this and Platypus, it must be protected from freezing. Mandatory. Failure to do so will ruin the filter and you may not be able to tell

Wish this drop had the 3 Way water filter option. I'm done buying bladders for now as all the bladders I have have a strong plastic tastes, Source Tactical and Camelbak.

Great filters but this kit needs a overhaul the bags are poorly designed. how much fun is it to get water into a soft bag with a side mounted inlet. Great if you have a tap
i have a custom kit using playtupus gravity bags. Similar to ekeppel post below using the larger squeeze filter.

T_ravThe filter isn't removable or replaceable. You back flush regularly to maintain its integrity.

Sawyer makes excellent light-weight filters. I've been using the original Sawyer Squeeze system in a custom gravity-feed configuration for years now. Here's a rundown of how to set up your Squeeze in a similar way:
For the grey water reservoir, you can just use an old Camelbak or other reservoir if you have one. Just make sure the hose fits the nipple on the Sawyer.
Cut off about 3 inches of tubing from the end, along with the bite valve, and attach the remaining tubing directly to the input of your Sawyer Squeeze. Then, attach the short length of tubing you cut off (along with the bite valve) to the output end. Hang the reservoir from a tree branch or somewhere it will be several feet above the filter, and you will have instant gravity fed water.
If you replace the bite valve with a small in-line on/off valve (which is how I use mine), you end up with a nice hands-free camp faucet for washing hands, dishes, filling water containers, etc... If not, you can simply drink directly from the bite valve or squeeze it with your fingers to use the water.
If you find the gravity flow rate too slow for your liking, simply buy some longer tubing to extend the distance (height) between the upper reservoir and the Sawyer. I find that hanging the reservoir on a branch about 5-6 feet up puts the filter at a nice height for camp chores and provides plenty of pressure.
It looks Sawyer has now done most of the work for us and put everything together in one neat package. Of course it costs a good bit more than just using the original Sawyer Squeeze with your own reservoir. One thing I don't see included is an on/off valve, which is nice to have.
I hope this info is helpful to someone out there! :-)
