Large-capacity essential oil diffuser with 2 mist settings and adjustable lighting

The QUOOZ Lull Ultrasonic Aromatherapy essential oil diffuser boasts an impressive 200-ml capacity and two settings, so you can choose to run the diffuser continuously, or in 20-second bursts. Using essential oils with the diffuser promotes peace and calm, while the adjustable lighting joins in with settings to help deep breathing and relaxation. If you want a large oil diffuser that can run all day, but won’t suck up a lot of energy, consider the Lull.

200-ml capacity

This is one of the larger oil diffusers. It holds 200 ml, so it can run for 8-10 hours, depending on whether you’re running it continuously or not. Adding essential oils to this water purifies the air and helps you fight illnesses like the flu, dry skin, coughs, and more. This makes it ideal for misting all through the night or at your office, where dust and all kinds of allergens are more consistent.

Adjustable lighting

Most essential oil diffusers have lighting, but the QUOOZ has adjustable lighting. You can turn it off, or adjust it to different brightnesses. It also has a “breathing mode,” where the light fades in and out, mimicking the rhythm of a breath. This can help relax you when you’re trying to sleep and ease anxiety.

2 mist settings

Operate your Lull diffuser on two settings – a continuous misting or one that emits every 20-seconds. The benefit of using the 20-second burst is a longer runtime, while the continuous misting is good for especially dry or smelly days.



Assuming you don’t want to keep track of how long the diffuser has been on, you’ll be glad for the safe auto shut-off. Once the water level reaches a certain point, the diffuser turns itself off, so it doesn’t continue operating and wasting energy. This is especially convenient if the diffuser runs out of water during sleeping hours.

No condensation

The Lull is able to do its job – misting cool and fragrant moisture – without building up condensation. This helps prevent the buildup of mold, which is bad for your health.


For a diffuser this large, it is actually pretty compact. It takes up about as much space as a smaller diffuser, and its stylish flower-bud design makes it a beautiful addition to bookcases, counter spaces, coffee tables, and more.


Tips over easily

The Lull isn’t super sturdy. It can tip over pretty easily, so you want to keep it out of reach of curious pets and children. You don’t want the diffuser to break from a bad fall. If you do want to keep it lower, just be sure it is on a flat, smooth surface so it doesn’t wobble.

Overall Review

The QUOOZ Lull Ultrasonic Aromatherapy essential oil diffuser offers the benefits of all oils diffusers – clean air, good fragrance, health-promoting mists – but in a larger package. It holds 200 ml of water and can run for up to ten hours. Combine that with the adjustable lighting, with a setting that imitates deep breathing, and you have an oil diffuser that’s perfect for people who suffer from insomnia and nighttime anxiety. A safe auto-shut off ensures no energy is wasting if the diffuser runs out of water during the night.
