What is the most important thing about respirator maintenance?

The most important aspect of respirator maintenance is indeed the storage of cartridges in an airtight bag. Proper storage helps to ensure that the cartridges remain effective for as long as possible by preventing contamination and degradation from environmental factors such as humidity, dust, and other pollutants. Respiratory protection is critical in pesticide application to safeguard the user from harmful inhalation of pesticides, and unprotected cartridges may not function correctly when needed.

While cleaning respirators with soap and water is important for hygiene, it does not directly relate to the maintenance of cartridge efficacy, which is crucial for protecting the user. Monthly replacement of cartridges is not a universal requirement, as the replacement schedule can vary greatly depending on usage, exposure levels, and the manufacturer's recommendations. Using cartridges until they show visible damage is counterproductive, as it defeats the purpose of employing a respirator to protect against hazardous materials. Therefore, storing cartridges properly provides the best assurance of their effectiveness when required.
