What Is a Nebulizing Diffuser?

• Stronger scent output

• Larger coverage area

• Suitable for premium brands and professional aromatherapy

• Often made with glass & wood for purity

📌 This aligns with luxury essential oil brands that emphasize purity, therapeutic effect, and natural wellness.

What Is an Ultrasonic Diffuser?

Ultrasonic diffusers use water + vibration to create a scented mist.

Key Features

• Requires water

• Lighter scent throw

• More budget-friendly

• Widely used in mass retail

📌 Ideal for consumers who want a decorative mini humidifier or mild scents.
