Nebulizers disperse a condensed amount of essential oil, and are good for an acute or short-term illness.
Do not use with pets or young children. Do not use for longer than recommended amount of time. If you want to diffuse for a longer period of time, then I would suggest an ultrasonic diffuser, they disperse a blend of essential oil and water.
Place 2-4 milliliters (40-80 drops) of essential oil into the glass basin or other holding area. Turn the diffuser on. The standard recommended time for a nebulising diffuser is 15 minutes for every 60-80 minutes. The ionized micro droplets will stay suspended in the air during the time the diffuser is off.
