Make replacement part of your routine
Follow your fountain manual for filter preparation and replacement. Clean the fountain and pump regularly; a fresh filter does not replace cleaning.

Do these filters fit D2431?
No. D2431 uses a separate filter, sold as an 8-pack. Choose the dedicated D2431 filters from the parts page.
How often should I replace a filter?
Follow the replacement guidance for your fountain. Water conditions and use affect maintenance needs. Contact PetNF if you need your model’s instructions.
Is the fountain included?
No. This listing includes four replacement filter cartridges, not the fountain.
