Introduction
The Earnest Living 100ml Waterless Diffuser is designed to disperse pure essential oils as a fine, visible mist without the need for water or humidification. This system allows for a pure scent experience, with intensity varying based on the essential oil type and room size. It is ideal for personal spaces up to 150 sq ft for optimal results. Crafted from high-quality metal with intricate engravings, this diffuser combines durability with elegant design, complementing modern interiors.
The diffuser features a built-in handle for easy portability, making it suitable for various active environments such as living rooms, offices, and entryways. Please note that this diffuser produces a gentle humming sound during operation, which is a natural characteristic of its nebulizing mechanism. It is best suited for ambient spaces rather than environments requiring absolute silence.

Setup Instructions
- Unpack the Diffuser: Carefully remove all components from the packaging. Ensure you have the diffuser unit, power adapter, and user manual.
- Place the Diffuser: Position the diffuser on a flat, stable surface. For optimal performance and to prevent oil residue on walls, ensure it is placed at least 30 cm (11.8 inches) away from any walls.
- Add Essential Oil: Gently remove the top cover of the diffuser. Insert your preferred 100% pure essential oil bottle into the designated slot. The nebulizing system works directly with the oil bottle, eliminating the need for water.
- Replace Cover: Carefully place the top cover back onto the diffuser unit.
- Connect Power: Plug the power adapter into the diffuser's power port and then into a suitable electrical outlet.
