This is a pair of Cartridges to suit our Half and Full Face Respiratory Masks
They are specifically for protecting you against Organic Acid Vapour or Acid Gas - Perfect for Vaporising Oxalic Acid or using with Formic Acid
The service life of any acid gas cartridge filter is affected by many factors.
Replace both the filters: -
- When the expiry date stamped on the sealed packet has elapsed.
- Once opened, maximum use time is 6 months (even if not used). The carbon will absorb contaminants from the general environment.
- When contaminant can be detected by smell or taste.
