Faith that a $20 cartridge can out-promise an entire municipal water system.
means A device that strains particles, chemicals, or microbes out of water to make it cleaner or better-tasting.
from 'Filter' traces back through French 'filtre' to Medieval Latin 'filtrum,' meaning a piece of felt — because felt cloth was literally used to strain liquids in early chemistry and brewing. 'Water' is one of the oldest words in the language, rooted in Proto-Indo-European 'wed-,' the same ancient root behind 'otter' and 'vodka' (literally 'little water'). So a water filter is, etymologically, just 'felt for your water' — the felt is long gone, but the straining spirit remains.
