The Quantum Collection elevates the level with five Sejoy humidifiers in a set for a large family or office with maximum savings. Each device disperses ultrasonic mist at 15–20 ml/h, supports oils, timer, seven colors, and touch control. USB 5V/2A, water-shortage protection, noise below 36 dB — all for comfort. This is a gift pack for five zones or corporate gifts. Savings are greater than in Vertex Collection.
