3M 6098 AXP3 Filter only
Limitations on the use of these filters may differ from one country to another but in
the absence of any limitations in your country the following should be applied.
a) Low boiling point organic compounds will be divided into four groups.
Low boiling point organic vapours with an Occupational
GROUP 1
Exposure Limit (OEL) of less than or equal to 10 (ppm).
GROUP 2 Low boiling point organic vapours with an OEL greater than 10 ppm.
Low boiling point organic vapours where protection is provided by
GROUP 3
filters other than AX (e.g. B, E or K).
Low boiling point organic vapours where no or insufficient
GROUP 4
protection is provided by gas filters.
b) Against compounds of groups 1 and 2, gas filters complying with EN371 can be
used up to the maximum concentrations shown in the table below or 100 x TLV,
MAK, WEL etc (depending on National requirements), whichever is lower.
GROUP Max Concentration (ppm)
GROUP 1 100 ppm
GROUP 1 500 ppm
GROUP 2 1000 ppm
GROUP 2 5000 ppm
c) Only new, unused filters from their original packaging should be fitted to your
facepiece. During one 8 hour shift, repeated use of an AX filter is permitted,
provided the maximum usage time shown in the table above is not exceeded.
The filter should not be used on a second shift even if these maximum usage times
are not exceeded. When changing filters ensure that both filters are replaced
simultaneously.
