Ultrasonic diffusers use high-frequency vibrations to break essential oils into microscopic particles, dispersing them into the air as a fine mist. These devices are among the most popular choices for home use because they're quiet, efficient, and add humidity to your space.
When using an ultrasonic diffuser, add 3-10 drops of your essential oil blend to the water reservoir, depending on the size of your room and your sensitivity preferences. For small rooms (under 100 square feet), 3-5 drops is usually sufficient. Medium rooms (100-300 square feet) work well with 5-8 drops, while larger spaces may need 8-10 drops.
It's important to clean your diffuser regularly to prevent oil buildup and maintain optimal performance. After each use, empty any remaining water and wipe the reservoir with a soft cloth. Weekly deep cleaning with white vinegar helps remove any residue.
