Functional Differences
Aromatherapy diffusers focus more on fragrance than humidification—they fill your space with cozy scents to set the mood and boost comfort.
Humidifiers put out way more mist than diffusers, making them perfect for rooms with low air humidity.
Principle Differences
Humidifiers are made to up air moisture: they have a larger atomizing plate that creates bigger, heavier mist particles—great for effective humidifying.
Diffusers prioritize mist movement, with a more powerful vibrating atomizing plate. This spreads scents to every corner, keeps natural essential oil components intact, and produces finer, more even mist.

Material Differences
Diffuser water tanks use corrosion-resistant PP plastic—safe for different essential oils, and easy to clean and maintain.
Humidifier tanks are usually ABS or AS plastic: just add water for humidifying, but they’re harder to clean.
Key Note!
Aromatherapy diffusers do more than smart scent diffusion—they work as humidifiers too. Humidifiers? Only for humidification.
