Description

The 3M

 Particulate Respirators 8825+ and 8835+ meet the 

requirements of European Standard EN 149:2001 + A1:2009, 

filtering facepiece respirators for use against particles. They 

provide effective respiratory protection for use in industries 

where workers will be exposed to solid (dust) particles and/or 

non-volatile liquid particles.

Technical Data Sheet

Applications

These respirators are suitable for use in concentrations of 

solid (dust) particles and/or non-volatile liquid particles up to 

the following limits:

Product

EN 149:2001+A1:2009 

Classification

*Many countries apply Assigned Protection Factors (APFs) 

which reduce the maximum concentrations of particles in 

which these products can be used. See national regulations 

and EN 529:2005.

Respiratory protection is only effective if it is correctly 

selected, fitted and worn throughout the time when the 

wearer is exposed to hazards.

Standards

Products are classified by filtering efficiency and maximum 

total inward leakage performance (FFP1, FFP2 and FFP3), also 

by usability and clogging resistance.

Performance tests in this standard include filter penetration; 

extended exposure (loading) test; flammability; breathing 

resistance and total inward leakage. Reusable products are 

also subjected to cleaning, storage and mandatory clogging 

resistance tests (clogging is optional for non-reusable 

products). A full copy of EN 149:2001+A1:2009 can be 

purchased from your national standards body.

Filter penetration

The filter penetration, initial and after 120mg of loading with 

both 120mg of NaCl* and Paraffin Oil, shall not exceed the 

following limits:

EN 149:2001+A1:2009 

Classification

Maximum Filter Penetration

FFP2

6%

FFP3

1%

*Loading of NaCl may be stopped if filter penetration during 

loading is observed to decrease.

Total inward leakage

Ten subjects perform five test exercises whilst wearing the 

respirator. The total inward leakage inside of the respirator 

due to face seal leakage, filter penetration and valve leakage 

is measured for each subject exercise. The subject mean total 

inward leakage for 8 out of 10 subjects shall not exceed the 

following limits:

EN 149:2001+A1:2009 

Classification

Maximum Total Inward 

Leakage

FFP2

8%

FFP3
