About: Ultrasonic Aroma Diffuser & Humidifier with LED – 300ML/500ML

300ml or 500ml Capacity

Choose the tank size that fits the room — a smaller desk or a larger bedroom setup.

Up to 300ml/h Mist Output

A strong ultrasonic output is rated for coverage up to about 10㎡, suited to a bedroom, car, or office desk.

Remote & Manual Control

Adjust the mist timer and 7-color LED from the included remote or the unit's own buttons.

Auto Shut-Off Safety

Built-in auto shut-off is designed to help the unit power down safely once water runs low.

Product Details

A bedroom that gets stuffy overnight, or a car that could use fresher air on a commute — the Ultrasonic Aroma Diffuser & Humidifier with LED is sized to handle both, in 300ml and 500ml versions. It pairs cool ultrasonic mist with a 7-color LED base, controlled from a remote instead of just the buttons on the unit.

Both sizes share the same CE-certified, BPA-free ABS/PP build, with mist output rated up to 300ml/h and rated coverage up to about 10㎡. Prices run from roughly $30.52 to $43.46 across the WYQS500, WYSS500, WYSS300, WYBS500, and WYBS300 finishes, each sold with EU or US plug options, and each currently listed below its compare-at price of up to $54.33.

A few drops of essential oil per 100ml of distilled water is enough to scent the mist, and the adjustable timer means it can be set to run for a fixed stretch rather than left on indefinitely. Operation stays under 36dB, quiet enough for a bedroom or a small office.

The 300ml size is a reasonable match for a desk, car interior, or smaller bedroom, while the 500ml option is worth the extra size for a primary bedroom or a space that needs to run mist through a full night without a refill. Either way, the shared remote control and 7-color LED come standard across both sizes.

Auto shut-off is built in to help the unit power down once the tank runs low, and weekly cleaning is enough to keep mist output consistent — a low-maintenance addition to a nightstand, desk, or car console. Because the LED, mist mode, and timer are all reachable from one remote, it also tends to suit anyone who'd rather adjust settings from bed than get up and press buttons on the base itself.

Top off the tank with a pick from our essential oil collection for a scented mist.

Why Choose Ultrasonic Aroma Diffuser & Humidifier with LED – 300ML/500ML

Two Sizes, One Design. Instead of committing to a single fixed tank size, this design comes in 300ml and 500ml versions, so the capacity can be matched to the room rather than compromising on either end.

Real Remote Convenience. Many compact diffusers only offer manual buttons on the base. Here, mist mode, timer, and LED color can all be adjusted from the included remote without getting up.

CE-Certified Build. The BPA-free ABS/PP housing is CE certified, which is worth knowing when choosing between this and a no-name alternative for daily use with a rotation of oils from our essential oil collection.

A Fair Price for the Feature Set. Priced from roughly $30.52 to $43.46 depending on size and finish, it sits well below its listed compare-at pricing of up to $54.33, without giving up remote control or the larger 500ml option.

Ultrasonic Aroma Diffuser & Humidifier with LED – 300ML/500ML Benefits

300ml or 500ml Sizing. Available in two tank sizes, so the same design can be matched to a compact desk setup or a larger bedroom that needs longer run time.

Remote-Controlled Misting. An adjustable timer and remote control mean mist settings can be changed from across the room instead of reaching for the unit itself.

7-Color RGB LED. Seven LED colors cycle through the base or hold on a single shade, adding customizable ambient light alongside the mist.

Auto Shut-Off Safety. Auto shut-off is built in to help the unit power down once water runs low, supporting safer daily and unattended use.

Shelf Life & Storage

After Each Use. Empty the tank and wipe it dry to reduce mineral buildup or mold growth.

Weekly Cleaning. Clean the tank weekly, or more often with frequent use, to keep mist output consistent.

Storage. Store in a dry place away from direct moisture, with the power adapter and remote nearby.

Longevity. With regular cleaning, ultrasonic diffusers of this kind typically hold up well over repeated use; we don't publish a fixed warranty length for this listing.

Safety Instructions

Water & Electricity. Never submerge the base, adapter, or cord in water.

Placement. Place on a flat, stable surface for even mist dispersion and to reduce tipping risk.

Fill Line. Do not overfill past the marked maximum line for your tank size.

Around Children & Pets. Keep out of reach of children and pets during operation.

Before Cleaning. Power off before cleaning or refilling the tank.

Running Dry. Avoid running the unit without water, as ultrasonic elements can be damaged if run dry for extended periods.

Oil Use. Do not apply essential oils undiluted directly to skin; this device is for ambient room diffusion only.

Caution & Disclaimer

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.

FAQs

Q: What's the difference between the 300ml and 500ml versions?
A: They share the same remote-controlled ultrasonic design; the 500ml tank simply holds more water for longer run time between refills, which suits larger rooms.

Q: How long does one fill last?
A: With mist output rated up to 300ml/h, a full tank is designed to run for a solid stretch of continuous use before needing a refill, depending on the mode selected.

Q: What oils should I use?
A: Use distilled water with about 2-3 drops of essential oil per 100ml of water; avoid thick, undiluted oils that could clog the ultrasonic disc.

Q: Is it safe to run all day or overnight?
A: Auto shut-off is built in to help power the unit down once water runs low, but as with any water-and-electricity device, keep the base and cord away from moisture and don't run it dry.

Q: How do I maintain it?
A: Clean the tank weekly to prevent mineral or residue buildup, empty and dry it after each use, and store it away from direct moisture.
