950ml water dispenser with ultra-quiet pump and water-softening filter, USB powered, and a user-friendly dish design. - Brand: GEX - Model Name: muty - Capacity: 950ml - Features: Ultra-quiet pump, USB power, water-softening filter - Ease of Use: User-friendly dish design - Recommended Use: For large dogs, indoor use I set it up with water, but my dog didn't even go near it. So, the dog hasn't even touched the water dispenser. It originally comes with one filter, but I'll include a set of 3 replacement filters (sold separately).
