Asthma is a chronic respiratory condition that affects millions of people worldwide, including children and adults. One essential tool in managing asthma symptoms is the use of an asthma spacer. For individuals who use metered-dose inhalers (MDIs), a spacer helps ensure that medication is delivered efficiently to the lungs, improving the overall effectiveness of asthma treatment. In recent years, disposable spacers have gained popularity due to their convenience and cost-effectiveness, especially in settings like hospitals and schools.
