The Squeeze filter with a 2 liter Cnoc bladder, clear.
Sawyer states a lightweight portable filter removing harmful bacteria, protozoa,
cysts, sediment and 100 per cent of microplastics; a reusable, easy-to-clean
filter lasting up to 100,000 gallons, whose hollow-fiber walls are thicker and
therefore stronger than typical hollow fiber, allowing more rigorous
backwashing; a Cnoc 2 liter bladder in extra-durable TPU with a wide mouth for
fast filling, BPA- and PVC-free; a system weight under 6 ounces including a
cleaning coupling and a cleaning plunger; and 0.1 micron absolute filtration,
meaning no pore is larger than 0.1 microns.
No flow rate. No thread named. Nothing on freezing.
Two liters at a time, through a wide mouth
Filling is the slow part.
The maker’s Mini comes with a 16 oz pouch, so two liters is four fills. This is
one.
Extra-durable TPU, wide mouth, BPA- and PVC-free, and it goes into a stream and
comes out full.
A claim about cleaning, not about pores
Thicker fiber walls.
Hollow fiber is a bundle of straws with pores in their walls. Backflushing pushes
water the wrong way through them to clear silt, and fibers split under it.
Thicker walls tolerate more of that — which is the claim that supports a 100,000
gallon life, because that life is only reached by cleaning the element many
times.
No thickness, no pressure, no backflush count is published. It is a comparative
claim.
A coupling and a plunger.
At least four of the sixteen listings in this group supply no backflush tool at all.
This shelf’s buying tip is explicit about why it matters: a neglected element loses
flow long before it reaches its stated liters.

What people ask before buying
Why pay double the Mini for the same micron rating?
For the bladder and for the element. The two-liter Cnoc pouch in extra-durable TPU with a wide mouth is the real difference in daily use: the Mini comes with a 16 oz pouch, so filtering two liters means four fills. The element difference is the maker’s own claim — fiber walls stated to be thicker than typical hollow fiber, therefore stronger, therefore tolerant of more rigorous backwashing, which is what keeps flow up over a 100,000 gallon life. No figure is given for the thickness, so it is a comparative claim. Both tools for using it come in the box: a coupling and a plunger, where the Mini supplies only the plunger.
What does a wide mouth on the bladder change?
Filling time, which is the slow part of filtering water. A narrow-necked pouch has to be dipped and coaxed and often needs a scoop; a wide-mouth two-liter TPU bag goes into a stream and comes out full. The listing states the mouth is wide for fast, easy filling, and that the TPU is extra durable and both BPA- and PVC-free. For a camp where two people want liters rather than sips, that is the format this shelf's introduction describes as a gravity bag’s advantage, applied with a squeeze.
Does the thicker fiber claim mean anything?
It is a real engineering argument with no number attached. Hollow-fiber membranes are bundles of straws with pores in their walls; backflushing pushes water the wrong way through them to clear silt, and the fibers can split under that pressure. A thicker fiber wall tolerates more of it, which matters precisely because the stated life here is 100,000 gallons — a life you only reach by cleaning the element many times. What the listing does not give is a wall thickness, a pressure, or a backflush count, so the claim has to be taken as stated. The maker’s instructions on backflushing and storage govern.
