Is the Homedics ARMH-800ST worth it?

It suits shoppers who want scent without water, mist or cleanup and are fine using SereneScent oils. At $79.99 at eBay as of November 7, 2026, it is the lowest of the four new listings, but budget for replacement oils.

Does it need water or a refill tank?

No. It is waterless and runs on SereneScent 120ml fragrance oils, so there is no tank to fill or rinse.

How long does the battery last per charge?

Homedics does not publish a runtime figure in the listed specs. Expect to recharge it periodically, and output is intermittent rather than continuous.

Can I use my own essential oils in it?

No. It is built for Homedics SereneScent oils, so other brands may not fit or perform as intended.

How big a room does it cover?

Homedics positions it for larger spaces such as bedrooms, living rooms and dining rooms. Scent strength depends on the intensity level and room airflow.

What comes in the box?

The diffuser unit and its rechargeable battery setup are included; fragrance oil is sold separately. Check the listing for the exact contents before ordering.

Our take on the Homedics ARMH-800ST-WW Waterless Home Fragrance Diffuser

The Homedics ARMH-800ST is a cordless, waterless fragrance diffuser that runs on SereneScent oils and releases scent intermittently at three intensity levels. It skips water, heat and mist, so there is no refilling or cleaning of a tank, and the rechargeable battery lets you place it anywhere in a room. It is compact at about 11.5 inches tall and 4.5 inches wide, with a fabric-wrapped body in black, blue or grey. The best new price is $79.99 at eBay as of November 7, 2026, the low end of what the four stores listing it new charge.
