The CompAir Compressor Nebulizer System (NE-C801) is a small, lightweight and convenient tabletop nebulizer that features OMRON advanced design and engineering. With only 52 decibels of sound while operating, it is similar to the sound of an electric toothbrush.* And at 9.5 ounces, it is 3.5x lighter than most tabletop compressor models. This small but mighty compressor nebulizer helps deliver medicine particles with an average size of 3 μm, which have a greater probability to penetrate into the deep lung. † The advanced engineering of this small nebulizer administers medication as effectively as tabletop models three times its size. The CompAir nebulizer system offers an affordable and efficient alternative for patients experiencing asthma, COPD or other respiratory conditions.
