How to use

Before fitting a replacement filter, inspect the mask and ensure it is compatible with size S Dragon cartridges. Remove the old filter following the mask manufacturer’s instructions and dispose of it according to local regulations for used PPE. Insert the new Dragon N99 filter into the mask’s cartridge receptacle until it seats securely and check the seal around the connection. Perform a basic fit check by covering the mask surface and inhaling to confirm a proper seal and normal airflow. Replace filters regularly or sooner if breathing resistance increases, the filter becomes visibly soiled, or after periods of heavy exposure.

Usage recommendations

Store unused filters in a dry, cool place away from direct sunlight and contaminants. Follow the mask manufacturer’s guidance on replacement intervals and fit testing. Do not attempt to wash or reuse disposable N99 cartridges; replace them when performance or cleanliness is compromised.
