500ML ARPSTAR Aromatherapy Essential Oil Diffuser

Sized for Bigger Rooms. Many compact diffusers hold under 300ml and need refilling mid-session; the 500ml tank here is built to outlast a full workday or overnight stretch.

Two Modes, Two Use Cases. Continuous mode suits active daytime use, while intermittent mode is the better pick for stretching a fill through the night without running dry.

A Genuine Dual-Purpose Device. Because it works as both a diffuser and a cool-mist humidifier, one unit filled with water from the tap, or paired with a bottle from our Essential Oil collection, covers two different needs.

Finish Options That Fit Most Rooms. The wood grain and pure white finishes are designed to sit comfortably in a living room or office rather than looking like a purely clinical appliance.

500ML Large Tank. A larger reservoir than most compact diffusers, it is sized for medium to large rooms that would otherwise need frequent refills.

Up to 12-Hour Runtime. Continuous or intermittent misting modes let a single fill run anywhere up to 12 hours depending on the setting.

Dual Mist Modes. Continuous mode delivers mist right away, while intermittent mode cycles output to extend runtime for longer sessions.

Humidifier & Diffuser. The same 500ml tank works with plain water for humidifying or with essential oil added for aromatherapy diffusion.

Step 1: Fill the Tank. Fill the 500ml tank with clean water, not exceeding the marked max line.

Step 2: Add Oil. Add 5 to 10 drops of your chosen essential oil for aromatherapy, or skip this step for plain humidifying.

Step 3: Choose a Mode. Select continuous mode for immediate, steady mist or intermittent mode to extend runtime.

Step 4: Power On. Plug in the unit and let the ultrasonic mechanism run through your selected session length.

Step 5: Clean Weekly. Empty and wipe down the tank once a week to keep the ultrasonic disc and mist output performing well.

What It’s Made Of. This is an electric appliance, not an ingestible or topical product, so there is no ingredient list here, only the components that make it work.

Housing. The sleek exterior is available in wood grain or pure white finishes over a durable plastic shell.

Mist Mechanism. An ultrasonic disc vibrates water (with or without essential oil) in the 500ml tank into a fine, cool mist.

Power Source. It runs on standard outlet power through an included power cord.

After Each Use. Empty remaining water from the 500ml tank rather than letting it sit between sessions.

Storage. Store the unit dry and away from direct moisture, with the power cord loosely coiled.

Longevity. Weekly cleaning of the tank and ultrasonic disc helps mist output stay consistent well beyond the first few months of use.

Water & Electricity. This is an electric device that holds water, so keep the power cord and connection dry and never submerge the unit.

Fill Level. Do not overfill the tank past the marked max line.

Children & Pets. Keep the unit out of reach of young children and pets while it is filled or running.

Before Cleaning. Unplug the unit before emptying, rinsing, or wiping down the tank.

Caution: For external use only. Keep out of reach of children and pets. Avoid contact with eyes, broken skin, and sensitive areas. This is an ambient fragrance diffusion device rather than a skincare or massage product, so it is not intended for direct application to skin.
