may be detected by odor, taste, and/or irritation. Replace cartridges daily, at the

damage. Always replace cartridges in pairs. Replace cartridges as follows:
A. Return to fresh air.
B. Remove cartridges by turning counterclockwise. Dispose of used cartridges
in accordance with Federal, state, and local guidelines.
C. Install new cartridges, taken only from sealed packages, as described in sec-

D. Perform a fit check as described in section VII.
