Respiratory filters protect against numerous known contaminants which, if inhaled, can be harmful to health: toxic gases, vapors or particles, as well as many combinations with immediate or delayed harmful effects.

Requirements for Selection

The efficacy of filters designed to provide respiratory protection is dependent on the ambient atmosphere:

• The oxygen content of the inhalation air must be sufficient, at least 17 vol. %!
• Type, properties and composition of the hazardous agent in the ambient air must be known. Material Safety Data sheets may contain this information.
• Local regulations concerning the use of filtering devices, the requested oxygen content and the threshold limit values may differ and must always be observed.
• Filtering devices must not be used in confined spaces such as containers, canals, etc. due to poor ventilation.
• Never use filters that show signs of damage.

If you are in doubt concerning any of the above-mentioned points, or if you believe that the composition of your atmosphere at work has changed, use protection that operates independently of the ambient air. MSA provides you with a wide range of breathing apparatus and airline devices. In any case, final choice and use of filtering devices remain the responsibility of the user.
