Source: sawyer.com (verified 2026-08-11). Sawyer's own product page confirms 0.1 micron absolute hollow-fiber membrane, removal of 99.99999% of listed bacteria, 99.9999% of listed protozoa, and 100% of microplastics, plus an included cleaning plunger and coupling for backflushing. No L/min flow-rate figure is published; the page states flow depends on filter cleanliness and altitude. Rated lifetime capacity of up to 100,000 gallons (378,541 L) and the 3 oz (85 g) filter-only weight are the long-standing, widely corroborated figures for this SKU; Sawyer's own page separately states an 8.19 oz figure that appears to be the packaged-kit weight including the included pouch and cleaning accessories rather than the bare filter. The Squeeze is a single sealed hollow-fiber unit with no separately swappable cartridge, so cartridge_replaceable is false.
