A spacer makes it easier to use an inhaler. It attaches to the inhaler on one end and to a mouthpiece or mask on the other end. When the medication from the inhaler is released, it's held in the spacer until the person is ready for it. Using an inhaler alone, the person needs to inhale immediately after releasing the spray medicine. If the person doesn't inhale at exactly the right moment, the medicine may end up in the person's mouth instead of in the lungs. Using a spacer helps prevent this from happening.
