Geigerrig water filter FYI
I am sure this does not go here but I thought what the heck.
I am not the originator of this idea of putting a geigerrig bag and sawyer filter together. That came from a guy over at BPL. I
expanded on it a bit.
The Geigerrig rig weighs a bit over 9oz out of the box and cost $45.
You can get the Sawyer 3 way from moontrail for about the same. The 3 way can also be used on a faucet for emer filter, or for
backflushing.
Put together as a water filter with the sawyer as shown below in pic 4 it weighs about 14 oz without the bottle. All of the fittings,
with the exception of the platy hose and bite valve came with either the sawyer 3 way or geiger. The barbs on the two are
different sizes so I used red silicone tubing which goes onto either.
I think I will switch the clean side to blue if I can ever find that tubing
Not sul but its a very useful rig and pretty much bomb proof.
You can use it as a clean bag regular pressurized bladder, dirty bag regular pressurized bladder, Dirty bag for a filter system,
good for cleaning wounds since its pressurized, with the right attachment probably a shower although I have not figured that out
yet, a pillow, and since the geigerrig is pressurized you can use it to backflush the filter in the field.
More importantly SHUG could pump it up to about 50 psi and power flush his nasal cavities. SWEET.
This is what my rig looks like so far.
Consist of a 3L geigerrig bag and a Sawyer 3 way filter. In filter mode it filters 2L of H20 in 2 minutes.
The geigerrig just as it comes..
With a platy hose, I will explain that below. Already had it.
Short silicone jumper hose with quick connect.
Setup still just a normal bladder.
Above goes into an elcheapo hydration pack when I go out hog hunting in the swamps. I carry a small bottle of chlorine and if I
run out of water the Platy bite valve connection will fit an Aquamira frontier pro. Sort of an emergency setup in case I run out of
water. You could also just put on the sawyer filter. Fill it up, drops, take off the bite valve, and put on the fronteir pro and good
to go.
Set up as a water filter with a Sawyer 3 way. If you were in a 3rd world country you would probably want to use the .02 micron
swyer filter with some chlorine drops or tablets. For a 2-3 more ounces you could add an inline Katadyn charcoal filter. This is
what it looks like.

Hmmm. Interesting. Never seen one pressurized like this. Is your 2L in 2 minutes with the bag pressurized? Once? Or with
occasional pumping to maintain pressurization?

Yes, 2L in 2 min pressurized. A .02 filter would probably be slower.
If the entire rig weighed 8 oz it would perfect, but it is versatile.

You could actually use this alone for water, IE no bottles.
So if you carry a pump water filter, 2-3 bottles, one of the shower setups, a syringe for cleaning wounds, a pillow then the 14oz
is not so bad.

I saw the setup on BPL and was also very intrigued. It's cool to see people pushing the envelope with new ideas. I like it. I'll
cheer from the sidelines though until they come up with something a bit lighter.

For me it made sense.
I live in hurricane country and at times we lose power and potable water for lengthy periods. Previously I had an frontier pro
gravity, but wet, the frontier pro and sawyer weigh within an ounce of each other. Also using it in a hydration pack is nice since
you dont have to suck the water out.
I can still always use 2 platys and the sawyer in gravity mode which is lighter at about 8 oz.

Is there any loop on the bag/closure for hanging?

You dont really need to hang it since it is pressurized, but there is a sort of small loop built into the back and it comes with a
small clip to clip into a pack.

There is one hole on one end of the plastic slide closer.
It would be easy enough to drill a hole in the other end of the closer

I will take a pic in a few.

Thanks for the pict. Yeah, I guess you wouldn't need to hang. I was just thinking in terms of replacing my MSR Autoflow gravity

...just thinking. But thanks for indulging me.

Down to 11.2 oz total.
Wet filter and replaced the main silicone tubing with vinyl tubing.

Replaced the silicone bulb tubing with a very short piece of vinyl tubing.

The bag and top clip itself weighs exactly 4 oz.
The bulb and short tube weighs 2oz.
With a lighter filter like the geigerrig filter and a lighter bulb if you could find one, you could probably get it down to 10 oz.
The geigerrig filter weighs 2 oz dry. Not sure wet, but probably not much less than a Sawyer.
Of course showing up at the medical supply office with your scale to weigh BP bulbs might land you in the loony bin.

BER, I'm in the same boat.... I have the MSR Autoflow too but I've been thinking about a DIY Sawyer filter with a Silnylon or
Cuben bag for the weight savings (~6oz). Only problem is, the darn Autoflow is just rock solid. It's fast, super easy to back-flush,
and I like the bag with disconnects. But it is 12oz's!! Hmmmmm..... decisions.... decisions.
P.S. ... Sorry Tammons, I didn't mean to hijack this thread. I am actually really intrigued by your project.

Hijack away.
That's cool. I have thought about a Cuben gravity too.

A chopped 2L platy weighs 1.2 oz. You just need the cap with the nozzle and some tubing.
That should also weigh about 6-7 oz.

I just bought one of those Geigerrigs with the Frontier Pro, after seeing it displayed at Damascus Trail days. Loving this thread.
It's a sweet system and the air pressure aspect works very well.

You will probably have to use a short piece of silicone tubing between the Geigerrig bag and the frontier pro, because the frontier
pro does not have barbs. You might be able to get a piece of tiewrap down in there, but its pretty hard to get to.

What it looks like at 9oz wet.
Stripped frontier pro.
Drilled a hole in the side of the bottle connector of the frontier pro to access
a zip tie to hold the silicone tube on. See pic.
Everything else is vinyl tubing from home depot. Had it a while.
Its just the right size to fit either end of the frontier pro.
It did not blow off when I tested it without, but I could see it loosening up after a while.

Just came across this thread and am very impressed with your rig. I'm in the market for a new bladder, I've got a Camelbak
unbottle now but was looking for more of a bare bones bladder with the slider opening. This thing looks awesome. I'm going to do
some more research, but I think I've found a new toy. Thanks for sharing!

FYI...the bag is dishwasher safe. You can turn the bag inside out and stick it in the dishwasher if you so desire. Or the opening is
so big you can just reach in there and wash it by hand. I love this thing.
