The Hydrex nebulizer mouthpiece with pacifier is intended for inhalation by infants and young children. The mouthpiece resembles a regular pacifier, which makes the inhalation process easier for little ones. It helps the child get used to the inhalation process and is a great alternative to masks, which can cause anxiety when applied to the child's face. The Hydrex mouthpiece is easy and comfortable to use and can be used repeatedly.
