Match your Dockstream model to official and third-party replacement filters—without mixing up generations, sponges, or old stock.
YOUR MATCH · PLWF116
PETLIBRO's replacement filter page says the filters suit Dockstream and Dockstream 2 but lists no model numbers, while its model comparison page marks the replacement filter for PLWF106 and PLWF116 as "Not Available For Now." Because these official pages disagree, check the model number on your fountain and the compatibility information printed on the filter package before purchase.

No. PETLIBRO assigns PLWF305 its own RFID replacement filter, which includes a pre-filter sponge alongside the cartridge. See the parts diagram.
