Introducing the Umbra Stream Water Fountain – modern style and convenience meet relaxation! This tabletop fountain offers more than just ambiance to any home or office space; it also helps improve air quality and can double as a humidifier. Plus, the integrated MAX and MIN water line indicators allow you to control how loud you want your streamed water, whether you prefer a peaceful murmur or a steady, soothing trickle. The Umbra Stream has plenty of room for 3.5" planters or stationaries, so you can add elements to this piece that will complement your décor perfectly. And since it's powered by a simple USB plug, you won't have to worry about cords and can easily control it with the on/off switch on the cord. Will run for 50 hours between refills at max water line. ⓘ Do not place on surfaces or tabletops that have potential to be water-damaged. Please ensure water does not fall significantly under the MIN water line indicator, as it will damage the motor. Use with distilled water only. Made of recycled plastic & wood fiber.
