Which Drinkwell fountains do these filters fit?

PetSafe says they work with most Drinkwell fountain models. Check your fountain's model number against the filter compatibility list before buying, since a few models use a different shape.

How often should I change the filter?

PetSafe recommends every 2 to 4 weeks to keep water fresh. Homes with multiple pets or heavy drinking may need the shorter end of that range.

Do these filter more than the standard Drinkwell filters?

Yes. The six compartments hold more charcoal than the standard filters, which PetSafe says gives longer-lasting, deeper filtration.

Should I rinse the filter before use?

Rinse it under running water before installing to wash out loose charcoal dust. Some owners still see a little dust in the bowl for the first day.

Will these filters work in other brands of pet fountain?

No. They are shaped for Drinkwell fountains, so they generally will not fit other brands without modification.
