Pur Water filter is not foolproof. A lot of giardia
infections occur not because the Pur water filter
malfunctioned, but because the person using it screwed
up. Usually, the filter, or bottle or hose with good
water is accidentally dunked or dropped in the water.
Ever worse, sometimes backwash is allowed to contaminate
the filter. When you consider that enough giardia
can reside in the drop of water around the screws
of a canteen or bottle to cause in infection, you
can see how easy it is for a small amount of bad water
in the filter to mess things up in a Pur water filter.
It's especially easy to make a mistake when you're
tired, which all backpackers are after a great day,
or when you do lots and lots of water for a group.
When we become careless.
Water Filter and kids
need to be taught how to properly filter water. The
safest and only really foolproof way I've found is
to have them put water in bottle, set it on the bank,
and filter a few feet away from the stream or lake.
That way when they drop something like the exit hose,
it doesn't plop into untreated stream water. It falls
on the grass.
So, let's say the unit is dropped in the stream. It's
contaminated. You can just keep using it, and probably
get away with it. Probably. If you want to make certain
it must be disinfected with Aqua Mira, Polar Pure
or Iodine, or even chlorine (Clorox). It's easier
to not drop it in the water. Backflushing with one
of the above disinfectants is always a good idea once
you get home and get ready to store the Pur water
- the latest hot thing in backpacking water purification,
and highly recommended.
