Regular cleaning and maintenance are crucial for the proper functioning and longevity of your nebulizer. Always unplug the unit before cleaning.

5.1 Cleaning the Nebulizer Kit (Chamber, Mouthpiece, Masks, Tubing)

1. After each use, disassemble the nebulization chamber, mouthpiece, and mask.
2. Wash these components thoroughly with warm water and a mild detergent.
