The LUMENA USB Bottle Desktop Humidifier will instantly make your workspace feel more comfortable. This USB humidifier also acts as an LED mood lamp, so it has two ways to create a warm environment. The subtle LED mood light displays through the glass-like bottom of the humidifier, illuminating in a unique way. Additionally, this device looks somewhat like a water bottle, and it has a 500-milliliter water capacity. Furthermore, it can continuously humidify or provide moisture in intervals. This, along with the fact that it produces 50 milliliters per hour of moisture, allows it to run for 24 hours on the interval humidification setting. If the air conditioning or heater makes your office extra dry, this compact humidifier will make you more comfortable.
