what's the difference between a nebulizer and an inhaler?

NEBULIZERS:

Nebulizers, or "breathing machines", are battery operated or electric machines that dispense liquid medicine into a fine mist that you breathe in. The mist comes up through a tube that is dispensed through either a face mask (especially for babies and young children who don't have to do anything during this time but breathe normally) or through a mouth piece (more common for adults or older children who know to breathe in when prompted to receive the medicine dosages).

Depending on the amount or types of medication, a standard nebulizer breathing treatment can take up to ten minutes to finish. This is the most common asthma treatment namely in infants or young children who are not required to breathe in and out upon prompting.

INHALERS:

There are two types of asthma inhalers. One is a metered dose inhaler which which is the most commonly used inhaler. They are like small aerosol cans that push out a spray of medicine for you to breathe in through your mouth. The second type is a dry powder inhaler which delivers medicine in dry powder form. The inhaler does not spray out any medicine and the user must inhale deeply to extract the powder out.
