Method: Fourteen backpacking water filters/purifiers verified 2026-08-11 primarily by live-fetching manufacturer product pages (sawyer.com, cascadedesigns.com for MSR/Platypus, lifestraw.com, grayl.com, hydroblu.com, aquamira.com); Katadyn's own site (katadyn.com) blanket-redirected every path tested, including its bare domain, /en/, /ch/en/, and sitemap.xml, to the katadyngroup.com marketing homepage during this session's automated checks (and katadyngroup.com itself returned 403 on deeper paths), so the three Katadyn entries (BeFree, Hiker Pro, Vario) could not be live-verified this session and are corroborated instead from well-established, repeatedly-published manufacturer spec sheets, with the source URL left pointing at Katadyn's standard current US product-page path as the correct manufacturer page despite the fetch block; their priceUsd figures use the long-standing published US MSRP rather than a session-confirmed figure. Two seed products from the suggested list were not found in the current catalog and were substituted with their real, currently-sold successors, matching the pattern used for prior discontinued-product corrections in this dataset series: (1) "LifeStraw Peak Squeeze" no longer exists under that name — LifeStraw's current squeeze-bottle filter in the Peak Series is sold as "LifeStraw Peak Series Collapsible Squeeze 1L Bottle with Filter" (confirmed live on lifestraw.com), which is used here as the direct successor. (2) "LifeStraw Flex" is discontinued and absent from LifeStraw's current 3-page full catalog (checked exhaustively); it has been replaced with "LifeStraw Peak Series Gravity Filter System – 3L", the closest current multi-use (bottle/gravity/hose) system in the same product family, confirmed live. Flow rate is left null wherever a manufacturer explicitly declines to publish a number rather than being estimated (Sawyer's three hollow-fiber models state flow varies with filter cleanliness and altitude and give no L/min figure; Aquamira does not publish one for Frontier Max). Filtration micron rating is left null for Grayl GeoPress (an electroadsorption/activated-carbon purification cartridge with no stated pore-size rating) and for Aquamira Frontier Max (not published on its own product page). accessedAt 2026-08-11 throughout.
