DIANU FD01 Cat Water Fountain, 3.2L Stainless Steel with Four-Stage Filtration

Size & fit

For a home where cats or a small dog need a steady place to drink, the DIANU FD01 holds 3.2 liters (108 oz) of water. Its visible water-level window lets you check the supply at a glance, while the larger capacity can reduce how often you need to refill it.

The stainless steel design gives this fountain a practical alternative to a plastic water bowl, with a gentle, continuously moving stream for everyday indoor use.

Where it shines

The four-stage filtration system combines a cotton layer, activated carbon, and ion exchange resin to help capture pet hair, dirt, and food particles and reduce odors. A pre-filter sponge catches larger debris and helps protect the pump. Together with the circulating flow, these features support a fresh water source pets can return to throughout the day. The flowing design is intended to encourage drinking by mimicking a natural water source, individual pets may respond differently.

Made from 304 stainless steel, the fountain is corrosion-resistant and supports high-temperature cleaning. The water-level window makes routine checks straightforward, so you can see when it is time to top up without opening the lid. Its 5V pump operates at a stated noise level of 25 dB or less, a useful detail for indoor spaces where a quieter water station is preferred.

Customer feedback commonly appreciates the quiet operation, simple setup, and ease of cleaning, with some owners saying it is easier to clean than plastic alternatives. Reports about durability are mixed, so feedback varies on how well the fountain holds up over time.
