Technical Information:

Microchamber device is made of a durable polypropylene plastic material. The holding chamber and built-in screen blocks large aerosol medication particles that normally deposit in the mouth and throat while allowing the smaller treatment particles to pass through and into the lungs. This provides effective treatment and helps to reduce unwanted side effects. Microchamber delivery system ensures adequate coordination time with the spraying of Inhaler. Microchamber helps inhale the aerosol medication more reliably.
