Answers built around real buying decisions.
What PETLIBRO's 2026+ purchase-date guidance confirms for the PLWF116, and why its own pages disagree about Dockstream 2 filter availability.
COMPONENT CHECKThe PLWF305 is assigned its own RFID replacement filter, not the classic Dockstream filter, and that filter includes a pre-filter sponge alongside the cartridge.
ORIGINAL GENERATIONPETLIBRO's Dockstream Replacement Filter page names these three models explicitly — the only official filter page that lists model numbers at all.
GENERATION SPLITPETLIBRO's official pages disagree about Dockstream 2 replacement filters, and only the cordless PLWF116 carries a documented purchase-date condition.
IDENTIFY YOUR UNITNarrow six PETLIBRO Dockstream fountains down to one using capacity, power type, and app support — and where PETLIBRO documents an on-device identifier.
REPLACEMENT INTERVALPETLIBRO states every two weeks for one pet, more often for multi-pet homes, plus a weekly interior clean. Here is exactly what each source says.
BUYING DECISIONCompare official filter pages, PETLIBRO's own marketplace listing, and third-party packs on who states the fit and which models they actually name.
