This diffuser features a large 400 ml water reservoir for extended humidification in spacious rooms, delivering a steady mist and aroma without frequent refills. It offers multiple operation modes including continuous mist and timed settings of 1 hour, 3 hours, or 6 hours, with 2 mist intensity levels to match comfort needs. When the selected time elapses or the water runs dry, the device automatically powers down to prevent overheating. A seven-color LED ring around the base provides a gentle ambient glow that can be left on or turned off as desired, creating a calm atmosphere without glare. Built from durable PP and ABS materials, the diffuser stays cool to touch and is easy to wipe clean; a wide base helps with cleaning access. The set includes ten essential oil options, each 10 ml, with scents such as peppermint, orange, lavender, tea tree, rosemary, eucalyptus, lemongrass, lemon, clove, and vanilla, enabling easy pairing with the diffuser for a blended fragrance. For safe operation, avoid refilling under running water and use a measuring cup to prevent splashing or circuit damage. Keep the water level below the max line, and power off before topping up. Do not drain from the air outlet; drain only from the drain side to prevent water ingress and circuitry damage. Color: Black.
