Ultrasonic foggers are devices that use high-frequency sound waves to create a fine mist of water droplets. They work by vibrating a metal diaphragm, which breaks the water into tiny particles, producing a fog-like effect. This technology is commonly used for humidifying air, creating special effects in theaters, or even in gardening to maintain moisture levels. These foggers are often used in various settings, including homes, greenhouses, and aquariums. They are energy-efficient and can operate quietly, making them suitable for indoor use. Ultrasonic foggers can also be enhanced with essential oils or other additives for aromatherapy or pest control purposes.
