Curator's pick: Berkey Gravity-Fed Water Filter
While heavy, the vertical flow rate on these is the only thing that keeps a group of four hydrated in camp without constant monitoring. Just watch the rubber washers on the lower assembly; if you overtighten them, they'll weep slowly and drain your reservoir overnight.
⚠ Worth knowing: Gravity filters are notorious for air-locking if the ceramic elements aren't fully primed; you cannot simply pour water in and expect an immediate flow if the filters have been stored dry. Also, if you are in freezing alpine conditions, any residual water in these elements will crack them, rendering the unit useless.
