Product Description:The Yuwell 405A Air Compressing Nebulizer is a light, a hand-held device meant to deliver medication via an inhaled mist. It uses an air compressor to pump air through the device. The compressed air through the nebulizer turns the medication into an aerosol, relieving symptoms such as asthma, Chronic Obtrusive Pulmonary Disease (COPD), or other pulmonary disorders. Its new, improved compact version is quieter, more efficient, and the DC motor reduces the atomization time significantly. Included in Package: Nebulizing machine, drug cup, mask, mask belt, filter, adapter, and tube.
