Ultrasonic Aroma Diffuser Manufacturer
Professional Diffuser Wholesale & OEM/ODM Supplier
√ Fine Mist & Long Lasting
Professional Diffuser Wholesale & OEM/ODM Supplier

An ultrasonic aromatherapy diffuser uses high-frequency ultrasonic vibrations to transform water and essential oils into a fine, cool mist. Unlike heat-based diffusers, it preserves the natural properties of essential oils while providing consistent fragrance distribution. Designed for home fragrance brands, gift companies, hotel projects, and appliance distributors, our models combine quiet operation, modern appearance, and stable performance. K-Star provide wholesale supply, OEM/ODM services, custom packaging, and compliance support for global B2B buyers.
The diffuser’s ultrasonic plate vibrates millions of times per second, breaking water and essential oil molecules into microscopic particles. These particles are released as a gentle mist that disperses fragrance evenly throughout the space. Most ultrasonic diffusers also feature adjustable mist settings, timer functions, LED lighting, and automatic shut-off protection, making them a reliable and safe scenting solution for both residential and hotel applications.

Creates a fine, consistent mist for better fragrance coverage and enhanced user experience.
Multiple lighting modes add visual appeal and increase diffuser attractiveness in retail markets.
Automatically powers off when water runs low, improving safety and reducing after-sales concerns.
Efficiently disperses essential oils, helping users enjoy long-lasting aroma with less consumption.
Low-noise operation makes it ideal for bedrooms, offices, spas, and wellness environments.
Simple structure enables quick cleaning, improving daily usability and customer satisfaction.
Flexible timing options support ultrasonic fragrance diffuser needs while improving convenience.
Supports logo, packaging, and product customization to help brands build market differentiation
