Platypus CleanStream Gravity Filter

I’ve been a huge fan of Jason Klass’ home-made Platypus gravity filtration system for some time, so much so that I copied the entire set up and now use that as my ultralight water filtration system of choice. Below is a video by Jason describing how his system works and the basic components necessary to make your own inexpensive gravity filtration system.

Enter Platypus! They’ve obviously been listening to their customers (and definitely Jason) because they’ve just released their own version of the two bag gravity filtration system. Even down to the labels used to indicate which bag is the dirty water bag and which one is the clean bag! It’s not cheap, coming in at around $90 at REI and it’s definitely more than doing it yourself – but for those of you that like the simplicity of buying a ready-done solution, this looks like a good one.

One difference is that the Platypus system used 4-liter bags instead of 2-liter ones like Jason, it also doesn’t seem to have the flexibility of the system Jason came up with as it doesn’t come with a bite valve. I’ll probably take a look at one in the store, but I’m certainly not going to change the one I have right now which works great!

    Hey Brian,
    Thanks for the mention. You can also use larger bladders with the system I describe if you want. BTW, cool blog. I’ve added it to my links list on my blog.

    Brian – I’ve been on the verge of moving to something like this. First need made some changes to their system that I don’t particularly appreciate. I like Jason’s system and think I’ll try it.

    Philip, the only drawback that I can see of this system is the difficulty in filling the dirty bag through the narrow bladder screw opening. Jason gets around this by using the scooper as described in his video.

    I like the way the Amigo Pro gravity filter works with the cloth dirty bag, much easier to fill.

    I’m considering just cutting the top off my top dirty bag bladder to make it easier to fill – otherwise this works great.

    The platypus dirty bag has a heavy duty ziplock type closure to make filling easy. On a shakedown this weekend we were able to filter 4 gallns of water in about 15 minutes and carry 2 more dirty back using another set of clean bags and. Filters.

      Very cool. Is that a new modification to the dirty bag? I thought the original bags didn’t have that – but I could be wrong.

        Well my troop has some newer ones, so it very well could be a recent thing.
