Difference of Nebulizer and Inhaler

Inhalers and nebulizers are devices that both deliver asthma medications to your lungs. However, they differ in their structural design and mechanism of action.

Nebulizers are electric- or battery-powered machines that turn liquid asthma medicine into a fine mist, which is breathed in through a mouthpiece or mask worn over the nose and mouth. A nebulizer is generally used for people who can’t use an inhaler, such as infants, young children, people who are very ill or people who need large doses of medication.

Inhalers are hand-held, portable devices that deliver asthma medication to the lungs. There are three main types of inhalers.

  1. Metered dose inhalers (MDIs) consist of a pressurized canister containing medication that fits into a boot-shaped plastic mouthpiece.
  2. Dry powder inhalers (DPIs) release medication by breathing in a deep, fast breath. DPIs can either be multiple-dose devices holding up to 200 doses or single-dose devices, which you fill with a capsule before each treatment.
  3. Soft mist inhalers (SMIs) are the newest technology that deliver a pre-measured amount of medicine in a slow-moving mist.
