A transparent hand pump filter, 0.2 micron, 11.2 oz.
Katadyn states a lightweight 11.2 oz microfilter pumping 1 liter of clean water
per minute, connecting directly to most water bottles and hydration packs; a
transparent body giving a clear view of the cartridge so there is no guesswork
about when to clean or replace; a 0.2 micron glass fiber cartridge filtering up to
1,150 liters, with activated carbon granules to improve taste, a filter protector
to extend cartridge life and a pre-filter on the intake hose to protect the
cartridge from debris; and three-step use with the supplied quick-connect fittings
and Easy Fill adapter.
No thread size. No backflush tool.
A liter a minute, the fastest here
And the only pump in this group.
The only other published flow figures on this shelf are 700 ml per minute. The
straws and squeezes publish none, because flow there is whatever you produce.
A pump also draws from a puddle, a rock pool or a silty margin, which is the
reason this shelf’s introduction gives for the format existing at all.
Eleven hundred and fifty liters, at ninety-nine dollars
The figure the buying tip is written for.
About 8.7 cents a liter. The Sawyer Mini in this group is eight thousandths of a
cent.
That is a factor of roughly a thousand, and it is not a mistake on either page:
this is a glass fiber and carbon cartridge, and carbon is consumed rather than
cleaned.
What the carbon buys is taste, which no membrane filter on this shelf claims.
You can see it loading
Which no other listing here allows.
Every element on this shelf loses flow as it loads, and on an opaque housing the
only symptom is slower water.
A clear body shows the cartridge darken. With the intake pre-filter and the
filter protector, this is the one listing in this group that treats loading as a
design problem rather than a disclaimer.

What people ask before buying
Is a pump worth the weight and the price?
For particular water, yes. A pump draws from a puddle, a rock pool, a silty river margin or a tap you cannot submerge a bag in, and it delivers a liter a minute into a bottle or a hydration pack through quick-connect fittings — none of which a straw or a squeeze pouch can do. The pre-filter on the intake hose is the other half of that case: silty water destroys a membrane, and this is the only listing in this group with a pre-filter. What you pay is 11.2 ounces, ninety-nine dollars, and moving parts that can fail where a straw has none.
Why is the cartridge life so short?
Because it is a glass fiber cartridge with carbon, not a hollow-fiber membrane, and because the carbon is consumed rather than cleaned. Eleven hundred and fifty liters is the figure this shelf's buying tip exists for: divided into ninety-nine dollars it is about 8.7 cents a liter, against eight thousandths of a cent for the Sawyer Mini in this group. That is not a small difference — it is a factor of about a thousand. What the carbon buys in exchange is taste, which no membrane filter on this shelf claims, and the transparent body means you see the cartridge darken instead of guessing.
What does the transparent body actually help with?
It removes the guesswork this shelf's introduction warns about. Every filter on this shelf loses flow as the element loads, and on an opaque housing the only symptom is that the water comes more slowly — by which point you are standing in a river wondering whether to clean or replace. A clear body shows the cartridge, so cleaning and replacement happen on sight rather than on a bad morning. Combined with the filter protector and the intake pre-filter, this is the one listing in this group that treats cartridge loading as a design problem rather than a disclaimer.
