ASAKUKI Essential Oil Diffuser for Home, 500ML Aromatherapy Humidifier

Why it's worth it

The 500ml tank runs for hours without attention, and the included remote lets you kill the light or change the mist from bed. It's plastic and the yellow finish is a choice, but functionally it's the most convenient ultrasonic diffuser here.

If refilling is the thing that makes you stop using a diffuser, this solves it. The 500ml reservoir is more than three times the top pick's, and on the lowest mist setting ASAKUKI claims up to 16 hours. In practice, you fill it before dinner and it's still going when you go to bed. Owners with master bedrooms and open living rooms are the ones who rate it highest.

The remote is the underrated feature. It works from about 16 feet, and it handles mist intensity, LED color and the 60/120/180-minute timers. Being able to shut the light off from bed without getting up is a small thing that you'll use every single night. Most diffusers at any price don't include one.

• –A 500ml tank means 15 to 25 drops of oil per fill if you follow the usual guidance
