miruto's USB-connected automatic water dispenser with filter, white. - Type: Automatic water dispenser - Color: White - Power: USB connection - Materials: Plastic and stainless steel - Features: The filter needs to be replaced regularly. The first filter is included. Thank you for viewing. I purchased three, but my cat only uses one, so I'm selling the others. It's hardly been used, but please refrain from purchasing if you are concerned about storage by a private individual. Please comment if you have any questions.
