Is $19.40 a good price for this diffuser?

It is the lowest new price among the two stores that list it as of November 8, 2026, so it is the best new price available. With so few sellers there is no long price history to compare against.

What bulb does it use?

A G40 E12 bulb at 25W. That is a small screw-base bulb, so keep a spare on hand.

How big a room will it scent?

Mocosa does not publish a coverage area or tank size. Treat it as a small-room or desk diffuser.

It is a bulb-heated diffuser, so it works with essential oil rather than a water tank. Follow the maker's instructions for how much oil to add.

Is it safe to leave on?

A 25W bulb gets warm. Do not leave it running unattended or near anything flammable.

Our take on the Mocosa Metal Essential Oil Diffuser

The Mocosa Metal Essential Oil Diffuser is a black metal diffuser for indoor use, sold with a G40 E12 25W bulb. Its metal body is the main selling point at this price, since most budget diffusers are plastic. At $19.40 at eBay as of November 8, 2026, it is the lowest new price among the two stores that list it, so there is little recent range to judge it against.
