Oh yes, they do. But there is another component that many do not know about as well. There is a filter on the air intake that can become clogged and lessen the effectiveness of the machine. For daily use it need to be replaced every 3-6 months on compressor type nebulizers. This will extend the life.

The Pari Vios, what I call the "old green machine" will work up to 10 years if well maintained without a noticeable loss.

The small, impeller type nebulizers only last from 6 months to a year with twice daily use. My InnoSpire Go need the head replaced each year, the battery pack can last quite a bit longer.

Which nebulizer did you wear out?
