300ml Capacity Ultrasonic Car Humidifier With AI Scent Spray 36db Noise Level

This 300ml Capacity Car Humidifier redefines on-the-go comfort with a blend of functionality and innovation, tailored for modern commuters and small-space users. As an ultrasonic humidifier, it operates at a whisper-quiet 36db—barely audible over soft car radio or office chatter—ensuring undisturbed relaxation during drives or work sessions.

Its compact, sleek design (matching the stylish blue finish in the image) fits seamlessly in cup holders, desk corners, or backpacks, making it versatile for cars, bedrooms, or cubicles. The 300ml water tank delivers long-lasting mist output: on continuous mode, it runs for 4–6 hours, while intermittent mode extends use to 8–10 hours, perfect for full workdays or road trips. The transparent water level window lets users monitor reserves at a glance, preventing unexpected shutdowns.

A standout feature is the AI Scent Spray function: paired with essential oil pads (included), it intelligently disperses subtle, customized fragrances (e.g., lavender for calm, citrus for energy) based on usage duration—no overpowering scents, just balanced aromatherapy. The ultrasonic technology atomizes water into fine, 1–5μm mist particles that absorb quickly into dry air, relieving dry skin, irritated sinuses, or static cling (a common woe in heated/cooled vehicles).

Safety is integrated: auto-shutoff activates when the water tank is empty, protecting the device and preventing hazards. The one-touch control button simplifies operation—press once for continuous mist, twice for intermittent, and hold for 3 seconds to activate the scent spray.

Constructed with durable, BPA-free materials, it’s easy to clean (the tank and mist nozzle disassemble quickly) and built to withstand daily use. Whether combatting dry winter air in your car, refreshing a stuffy office, or adding a calming aroma to your workspace, this humidifier merges practicality, quiet performance, and smart scent technology into a single, portable essential. It’s not just a humidifier—it’s a compact wellness tool that elevates daily routines with minimal effort.
