Olivia Bennett — Diffuser Hardware Editor

Diffuser Hardware Editor

Olivia Bennett leads diffuser-hardware coverage at Aroma Paradise. She tests every category we sell — waterless cold-air, ultrasonic humidifying, nebulizing, plug-in, car, and HVAC-integrated — and writes the comparisons that help readers choose the right device for the right room size, oil format, and use case.

Olivia is an industrial designer by training and spent four years working in product design for home appliances before joining Aroma Paradise. She approaches diffuser reviews the way an engineer approaches a teardown: capacity, coverage area, intensity-step granularity, droplet size, BPA-free plastics, motor noise at every speed, app pairing reliability for the Tuya and Smart Life devices.

Her hardware cluster — the waterless-vs-ultrasonic explainer, the diffuser-format comparison, the HVAC+ home-system integration guide, and the regular reviews of new tower and plug-in releases — is the most frequently cited reference in support-team replies to pre-purchase questions.
