The Kogan SmarterHome™ 1.9L Pet Water Fountain is designed to keep your pet’s water fresh and purified. It features a 6-stage filtration system and a built-in UV light that sterilizes the water. It also has an angled lid to protect your pet’s spine and low voltage power for safety. You can monitor water and filter levels from the SmarterHome™ app and receive low water and filter replacement alerts. The fountain has a 1.9L capacity, and the top lid holds up to 80mL of water in case of a power outage, plus an anti-dry burn protection feature. To ensure the best filtration, it is recommended that you replace the filter once a month.
