Wholesale Ultrasonic Electric Aroma Diffuser

What is Ultrasonic Electric Aroma Diffusers?

An ultrasonic electric diffuser is a device that uses high-frequency ultrasonic vibration to turn water mixed with essential oils into an ultra-fine, cold mist, then gently disperses the mist into the air to spread fragrance, humidify dry air, and create a scented atmosphere—ideal for wholesale and bulk purchase.

How it works

A small ultrasonic transducer inside the unit vibrates at a very high frequency (usually 1.7MHz–2.4MHz). We use a 2.4MHz ceramic atomizer from Jiayeda, ensuring stable performance for your bulk and OEM orders.It breaks the water–essential oil blend into micro mist particles without heating.A fan or natural airflow releases the mist, so the scent and beneficial components of essential oils are preserved— a key advantage for your wholesale and Private Label products.

FAQ About Our Wholesale Ultrasonic Aroma Diffusers

A: Ultrasonic aromatherapy diffusers use high-frequency ultrasonic vibration to turn water and essential oils into cold mist, which helps preserve the natural nutrients of the essential oils. Unlike heat diffusers (which may damage the components of the essential oils) or nebulizers (which require oily essential oils), ultrasonic electric diffusers are more energy-efficient and quieter, making them perfect for daily use at home and in the office, and also a popular choice for wholesale and bulk purchases. Besides, they also have a humidifying function that most other types of diffusers don’t have. However, they’re not as quiet as ultra-high frequency diffusers, need regular cleaning, and aren’t very portable—factors to consider for your bulk order planning.
A: Sure! We support custom colors for the diffuser body (made of high-end ABS/food-grade PP material) to match your brand aesthetic for wholesale, OEM and Private Label orders. We have standard colors in stock for quick bulk order fulfillment, and we also accept custom colors for OEM and wholesale bulk orders. In addition, we offer services like laser engraving your logo on the diffuser surface, as well as silk-screen printing, labeling, custom packaging and user manuals—all tailored for your Private Label and bulk order needs. Even small trial orders are acceptable to help you test the market before placing a large wholesale bulk order. We also support customizing different exterior materials, such as glass, resin, ceramics, carbon fiber, solid wood, Spanish marble, etc., and can add battery customization.
