How often should I replace the filter?

Replace the DIANU filter and pre-filter sponge every 1-2 weeks for best results. Homes with multiple pets, hard water, or heavy use may need a faster routine.

How should I clean the fountain?

Unplug the fountain, empty the water, and rinse water-contact parts with warm, soapy water. Keep the pump path clear and refill with fresh water.

Can cats and dogs use it?

Yes. DIANU is designed as a pet water fountain for everyday home hydration, with moving water that can feel more inviting to many cats and dogs.

How loud is the pump?

The pump is designed for quiet indoor use at about 25 dB. Keep the water level topped off and the pump path clean for the quietest operation.
