HJTHJT 500ml Essential Oil Diffuser - Black Ultrasonic Humidifier, 14-Color LED & Remote

HJTHJT 500ML Essential Oil Diffuser is a large-capacity ultrasonic humidifier and aroma diffuser with 14 LED colors, adjustable mist levels, remote control, and whisper-quiet operation designed for home use.

This compact black diffuser combines a substantial 500 ml water tank with ultrasonic misting technology to gently disperse fragrance and increase ambient humidity across bigger rooms. It offers flexible mist output, a multi-color LED system that can be fixed or cycled, convenient remote control, and built-in safety shut-off. The unit is intended to refresh living spaces, bedrooms, nurseries, or offices without creating excess moisture on furniture.

How does the HJTHJT diffuser deliver scent and humidity throughout a room?

The diffuser uses ultrasonic vibrations to convert water and a few drops of essential oil into a fine, cool mist that spreads scent evenly. Two mist settings let you tailor output to room size and desired intensity, while the 500 ml reservoir runs longer between refills.

• Ultrasonic atomization for consistent, cool mist
• Two flow rates: low 30 ml/h and high 60 ml/h
• 500 ml tank supports extended operation without frequent refilling

Can I control lights, mist, and timing without touching the unit?

Yes — the diffuser includes a remote that works up to about 15 feet away, enabling you to change light modes, mist level, and set timers from across the room. Built-in timer options and a steady-ON mode give you flexibility for daytime use or overnight diffusion.

• Remote adjusts mist settings, LEDs, and timer functions
• Timers: 1 hour, 3 hours, 6 hours, or continuous ON
• Auto shut-off protects the unit if water runs out

What lighting options does the diffuser offer and how do they work at night?

The diffuser features 14 LED color variations arranged as seven base colors with two brightness settings, which can be set to a single hue or allowed to cycle through hues. Lights can be turned off independently, so you can enjoy aromatherapy without illumination while sleeping.

• Fourteen-color LED system with fixed or rotating modes
• Light and mist operate independently for customizable use
• Low-light and night-friendly settings for sleeping areas

Does the HJTHJT diffuser make noise and is it safe for overnight use?

This model uses a low-noise fan and upgraded quiet technology to keep sound levels under roughly 25 dB, making it suitable for bedrooms, nurseries, and workspaces. An automatic shut-off engages when the tank is empty to avoid overheating and protect the unit.

• Noise-reduction design produces a peaceful environment
• Under ~25 dB operation compatible with sleep and study
• Auto power-off prevents running dry and protects electronics

Who is this for? The HJTHJT 500ML diffuser is ideal for people who want a reliable, longer-running aroma diffuser and humidifier for medium to large rooms — homeowners, apartment dwellers, office workers, and those who prefer remote operation and adjustable lighting. It's a practical option for anyone seeking to boost indoor humidity gently, add scent to living spaces, or create a calming atmosphere without a noisy appliance.
