Medicare switched me to Lincare as my service provider for nebulizer equipment. When a new compressor and cups were delivered I was given directions for use. The provider told me that Lincare believes that washing the nebulizer cups with soap is to be avoided because bubles can form and interrupt the flow. The care provider showed me how to simply rinse all equipment ( except hose of course) under a faucet with my hands in warm water. I had always been washing the pieces with soap and water and then rinsing them after each use and actually boiling the pieces for 10 minutes once a week. . What do others do?
