These Gas/Chemical Filters are designed for MSA Advantage® Single Filter Respirators; MSA Advantage® 410, Advantage® 3100, Ultra Elite® and 3S single filter cartridge respirators.
These high-performance filters provide strong protection against gases and gas/particles. Reliable against both organic and inorganic vapours. MSA’s PlexTec particle filter technology increases filtering surface for easier breathing. Available in gas filter classes 1 or 2, single array or multiple range.

The following are all indicators that its time to replace your filter:
The expiration of the service life of gas filters can be detected by odour or tasted on the clean air side. The filters must then be replaced.
The expiration of the service life of particle filters or combined filters that are used against particles can be detected by an increase in inhalation resistance.
With combined filters – depending on the predominant protective function – both criteria must be observed. Particle filters must only be used once against radioactive contaminants, spores, bacteria,viruses and proteolytic enzymes.
Some filters have a specified maximum service time (CO filter cartridges, combined filters 93 Hg/St) or they have an incorporated warning system (CO filter canisters).
Filters that are used against hazardous gases whose infiltration cannot be detected by odour, taste or irritation, are subject to special regulations concerning duration and usage that depend on the conditions of use. Otherwise a form of protection that functions independently of the ambient air must be used.
Further conditions of use in each individual workplace and of each user affect the service life of respiratory devices, such as:
Pace of breathing – the higher the rate of breathing the higher the contamination rate of the filtering device
Temperature of the ambient air – the higher the temperature, the shorter the service life
Humidity – the higher the humidity the lower the intake capacity of activated carbon against organic gases and vapours
Mixtures of hazardous agents – less absorbent components in the activated carbon can be replaced with components that offer higher rates of absorption (desorption)
For factory sealed and properly stored gas and combined filters the following storage lives can be expected:
Filters type A, AX, B, E, K, Hg, Reactor : 6 years Filters type CO, NO : 4 years
Proper storage conditions are indicated on the filter packaging. The expiration date is marked on the individual filters. Gas and combined filters that have been opened must be replaced after 6 months at the latest, or earlier if they are exhausted.
