How long does one fill last?

The 15ml reservoir is rated for about 30 days of use. Actual life depends on how often and how long you run it each day.

Do I need to add water?

No. It is a waterless diffuser, but it is made for diluted oils rather than neat essential oils, so check your oil's dilution before use.

Is it quiet enough for a bedroom?

It uses ultrasonic diffusion and is described as super-quiet, so it should not disturb sleep. It still makes a faint hum when running.

Can I use it in a large living room?

It is better suited to small and medium rooms. The 15ml reservoir and low output mean scent will be faint in large open spaces.

The diffuser unit itself. Oils are not included, and you supply your own diluted oils.

Our take on the Essential Plugin Waterless Oil Diffuser

The Essential Waterless Oil Diffuser is a plug-in ultrasonic diffuser that runs on diluted oils from a 15ml reservoir, which the brand says lasts about 30 days. It is waterless, so there is no tank to fill or clean, and it is built in pearl white polypropylene. At $49.87 at Best Buy as of November 7, 2026, it is the lowest new price among the two stores that carry it.
