However, I also noticed that they sure didn't spend much effort on printed
material. The brochure showing their product line was a nice glossy one, but
the instructions were two photocopied computer-printed sheets with NO
illustrations. Now how do I assemble this thing. Oh, back on the second page
they cover Filter Replacement. Still, it took some looking to see where the
filter element installed. A couple of simple drawings, nothing fancy, would
have been very helpful. Also, I had to look hard to find which end was "in"
and which was "out." A big arrow imprinted on the body to show water flow
would have made that easier.
There were no instructions on cleaning the filter. Should it be brushed or
backwashed? Without complete instructions, the part I've heard refered to as
a backwash device I assumed to be for filtered faucet water as shown in
their brochure as the Tap2Pure filter. I agree it would made a great
I also noticed a bit of blackish grit in the filter system, apparently from
the filter element itself. The filter element looked fragile, like a bit of
foam pipe insulation. A gentle brush with a finger tip would remove more
grit. I gently screwed the element into the body of the filter, worried I
would tear the element. I flushed as instructed and the water appeared to be
Once assembled on my platy system, the filter primed quickly. I was
impressed with how easy it was to draw water through the filter to my bite
tube. It sure was easier than pumping my MSR, and a whole lot lighter! I
wondered how well it worked, and proceeded to the dye test.
I added a bit of yellow food coloring to the platy, and saw that the yellow
color was only slightly faded on the output of the filter. I'm not sure it's
not filtering the germs out, but my other filters have all taken all the
color out. I could just imagine how silty desert stream water will look.
I then removed the filter element to look at the O-ring that has been
questioned. It looked ok, so I again carefully screwed the element back into
the filter. The threaded nipple then BROKE OFF where the O-ring was located.
If this was my only filter in the field I would be out of luck, or using my
backup tablets. I am concerned that, being careful in my kitchen, I broke
the filter. I could see damage being easier to inflict when tired after a
hard hike or in bad weather. Also, a bit of sediment in the threads would
increase the chances of damage.
So, in summary:
Can they provide better and illustrated instructions?
Why did the filter fail the dye test?
Why did the filter element nipple break off so easily?
How would this filter perform in silty conditions?
I still need to find a replacement for my too-heavy MSR miniworks, but until
I can trust something else, the MSR has never failed me.

_how_ the filter goes about removing all the nasties I don't want to
drink, and I doubt any consumer who has just purchased the product would
be either. What I AM concerned about is how to put the thing together and
assure that I use it correctly so it WILL remove the nasties. And
although it was fairly simple to assemble, some directions would have been
2) Relating back to #1, for a while I had no idea what the rubber piece
was for. I read the "directions" several times, and made myself feel like
a complete idiot because I couldn't figure out where the rubber piece was
supposed to go. It made no sense to me that it would go in the filter,
but I figured they wouldn't include the thing if it didn't serve a
purpose. It wasn't until I looked through their brochure and saw their
Tap2Pure system that I figured out that it's just a faucet hookup. One
that could be improved by making it a tighter fit to the filter, I might
3) When I screwed in the filter element, it appeared to not go in
straight, and was perched at an angle (despite being fully screwed in).
This made it somewhat difficult and consternating to screw the rest of the
casing on, although I did manage it with some care.
4) I am yet to hook the filter up to my hydration pack, for I am wary of a
couple of things. Will it leak? Will it force me to change how I carry
and use my hydration pack (I keep it in a special pouch at the top of my
Gregory Shasta, and run the tube down under my arm and up to a hook on my
shoulder strap)? Perhaps anyone who has already hooked theirs up can
assuage or confirm my fears.
5) After giving it a test run on the faucet, I blew the remaining water in
the system out with my mouth, and got a TERRIBLE taste in my mouth. The
taste wasn't as strong on the out side (either that or I was used to it),
but I am still concerned about whether the filter could affect the taste
of the water when used in the hydration pack as intended.
And now for the positives . . .
1) Water seems to flow through the filter very easily, which is always a

leaking or otherwise failing.

5) The element appeared to flush very quickly.
I will give it a more rigorous test this weekend on a small trip, but I
thought I'd send a few initial comments. SO far my main observation is
INSTRUCTIONS, INSTRUCTIONS, INSTRUCTIONS!!!! They don't cost that much,
and it would have helped me out a lot.

Personally, like any filter I would expect it to eventually clog in
silty conditions. What we need to know is how does it perform after
rinsing it out. Does it flow freely again until sediment clogs it
again? If so, that would be very acceptable, IMO. If it didn't clog
in silty conditions, I'd be pretty worried.

If it clogs in those conditions and a simple rinse allows it to flow
freely again before clogging again, then I couldn't as for more than
that from a filter. If it didn't eventually clog under those
conditions, I'd be pretty worried.
