No Masks and No Carrying Case. For those who do not use a nebulizer mask, this Lumiscope nebulizer is a wise option. Updated in design, this quiet, lightweight, efficient compressor nebulizer has a piston driven compressor motor. This compact medical device is designed to efficiently deliver physician prescribed nebulizer medication to the bronchial lung passages. For pediatric through geriatric use. Physician's prescription is required by Federal Law before a nebulizer can be shipped to customers within the United States of America. Developed for the treatment of asthma, allergies and other respiratory disorders, the Lumiscope nebulizer creates a stream of air that travels through clear tubing to the nebulizer. Air entering the compressor nebulizer converts the medication into aerosol mist for easy inhalation.
