Product Information

Overview

The Saintdeland 1500mL Ultrasonic Diffuser is designed for large rooms and open spaces. Combining a generous water tank, whisper-quiet operation, and Saintdeland’s cutting-edge dual-fluid atomization technology, it delivers a fine, even cool mist that fills spaces quickly and maintains a stable, long-lasting fragrance experience.

Key Benefits

Advanced Atomization for Uniform Scent

Our proprietary dual-fluid atomization creates ultra-fine droplets that spread evenly across the room. This means a consistent scent profile with less oil waste and a smoother, longer-lasting aroma compared to ordinary diffusers.

Large 1500mL Capacity & Extended Runtime

The large tank supports extended continuous operation—ideal for living rooms, studios, offices, and hospitality spaces. Fewer refills and uninterrupted fragrance make it perfect for busy homes or commercial areas where consistent scent matters.

Whisper-Quiet Cool Mist

Engineered for low noise, the unit produces a quiet cool mist that won’t disturb sleep, work, or conversation. The gentle operation keeps the air comfortably humidified while dispersing scent without heat, preserving fragrance nuances and essential oil integrity.

Smart, Simple Controls

Intuitive buttons and multiple mist settings let you customize intensity. Easy-to-read indicators and safety features like auto shut-off on low water bring peace of mind. The sleek design blends into modern interiors and is easy to clean and maintain.
