## Long description

The Clean Air Optima AD-302 ultrasonic aroma diffuser is a compact, USB-powered device designed for fragrancing and light humidifying of indoor spaces up to 60 m² (volume up to 150 m³). Its transparent water tank and white cylindrical housing create a discreet appearance suitable for home or office. The diffuser uses ultrasonic atomization to disperse essential oils as a fine mist while operating with low energy consumption (5 W). Controls on the front panel allow selection of continuous or interval diffusion and activation of seven subtle colour-change lighting effects or a fixed light colour.
Advantages
The AD-302 offers ultra-quiet operation and energy-efficient performance, consuming a maximum of 5 watts. A visible water level indicator helps ensure the correct water-to-oil ratio for effective atomization. Seven integrated lighting modes provide ambient illumination that can alternate automatically or remain on a single colour. Simple two-button control makes operation straightforward, and the USB power option supports flexible placement near computers, chargers or USB adapters.

Living rooms and bedrooms

How to use
Place the diffuser on a flat, stable surface and connect it to a USB power source rated for AC 220–240 V via an appropriate adapter. Remove the tank cap and fill the transparent reservoir with fresh water to the indicated level; add a few drops of essential oil if desired. Replace the cap, press the Power button to choose continuous or interval diffusion, and press the Light button to select alternating lighting or one fixed colour. The built-in water level indicator helps maintain the recommended water and oil ratio for optimal atomization. Turn off and unplug the unit before refilling or cleaning.
Usage recommendations
For routine use, operate the diffuser in a well-ventilated room and start with two to three drops of essential oil in the reservoir to assess fragrance strength. Clean the water tank, ultrasonic transducer and base at least once a month, and replace water frequently to avoid scale or residue. If the unit will be unused for a long period, empty and dry the tank before storage. Use high-quality essential oils suitable for ultrasonic diffusers; avoid undiluted viscous substances and solvents.
