-Nozzle and pump system: Common materials include polypropylene (PP), silicone, or TPE thermoplastic elastomers, which are soft, non-toxic, corrosion-resistant, and suitable for contact with nasal mucosa.

-Dust cover: usually made of polyethylene (PE) or polypropylene, used to protect nozzle hygiene.
