Sawyer Micro Squeeze Filter with Cnoc Premium 750 ml Pouch

What it removes from water, and how well that is proved. 6: A bit better than average.

0.1 µm hollow-fibre membrane. Sawyer claims 99.99999% of bacteria and 99.9999% of protozoa and says this exceeds EPA recommendations, but names no standard and links no test report for the Micro Squeeze. Its published reports cover the Mini (USEPA 1987 protocol) and the full-size Squeeze (NSF P231), not this filter, so the Micro is claimed with no published test: 3. No virus claim.

How fast clean water comes through when it is new. Real flow drops as it clogs: see Ease of use. 5: Does the job. Average for wild-camping gear.

Estimate from maker's specs

How much it adds to your pack. 8: Clearly better than most.

Sawyer says the kit weighs under 113 g, and Adventure Alan's comparison table lists this exact kit, the Micro with its 750 ml Cnoc pouch, at 96 g: 90–149 g. Ultralight Outdoor Gear heads its page 87 g, which would be the under 90 g band, but the specification table on that page is headed for the Cnoc 1 L bottle kit, so we take the figure that names this kit. The 145 g on Sawyer Europe's page is a shipping weight.

Filling, squeezing or pumping effort, how fast it clogs in peaty or silty water, and how easy it is to clean. 7: Better than most.

Easy to set up, but the small filter clogs sooner. Oscar Hikes (nine months) and Campology rate it simple and effective; Jeremiah Stringer's flow dropped after a week on a three-week trail despite daily backflushing, and Adventure Alan calls the Micro slower and more clog-prone than the Squeeze and finds the 750 ml pouch too tall with the filter on. Two score 4 and two score 3: average 3.5 out of 5, so 7 out of 10. These reviews cover the Micro filter; Adventure Alan is the only one to test it with the Cnoc Hydriam 750 ml.
