Description
The 3M™Particulate Respirators 8825+ and 8835+ meet the
requirements of European Standard EN 149:2001 + A1:2009,
ltering facepiece respirators for use against particles. They
provide eective respiratory protection for use in industries
where workers will be exposed to solid (dust) particles and/or
non-volatile liquid particles.
3M™Particulate Respirators
8825+ and 8835+
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
Classication
Maximum
Workplace Exposure
Limit (WEL)*
8825+ FFP2 R D 12
8835+ FFP3 R D 50
*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 eective if it is correctly
selected, tted and worn throughout the time when the
wearer is exposed to hazards.
Standards
Products are classied by ltering eciency and maximum
total inward leakage performance (FFP1, FFP2 and FFP3), also
by usability and clogging resistance.
Performance tests in this standard include lter penetration;
extended exposure (loading) test; ammability; 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 lter penetration, initial and after 120mg of loading with
both 120mg of NaCl* and Paran Oil, shall not exceed the
following limits:
EN 149:2001+A1:2009
Classication Maximum Filter Penetration
FFP2 6%
FFP3 1%
*Loading of NaCl may be stopped if lter penetration during
loading is observed to decrease.
Total inward leakage
Ten subjects perform ve test exercises whilst wearing the
respirator. The total inward leakage inside of the respirator
due to face seal leakage, lter 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
Classication
Maximum Total Inward
Leakage
FFP2 8%
FFP3 2%

Breathing resistance
The breathing resistance of the respirator is tested during
inhalation (continuous ow) and exhalation (cyclical ow). The
breathing resistance of the respirators shall not exceed the
following limits:
EN 149:2001+A1:2009
Classication
Maximum Breathing Resistance
Inhalation at
30l/min
Inhalation at
95l/min
Exhalation at
160l/min
FFP2 0.7 mbar 2.4 mbar 3.0 mbar
FFP3 1.0 mbar 3.0 mbar 3.0 mbar
Clogging
For single shift use respirators (NR), the clogging test is
optional. For re-usable respirators (R) this test is mandatory.
The respirators are loaded with very high amount of Dolomite
dust which will tend to clog the lter. After loading with the
required amount of dust, the breathing resistance of the
respirators shall not exceed the following limits:
EN 149:2001+A1:2009
Classication
Maximum Breathing Resistance
Inhalation at 95l/min Exhalation at 160l/min
(continuous ow)
FFP2
5.0 mbar (valved
respirator)
4.0 mbar (unvalved
respirator)
3.0 mbar (valved
respirator)
FFP3
7.0 mbar (valved
respirator)
5.0 mbar (unvalved
respirator)
3.0 mbar (valved
respirator)
Flammability
Tested respirators are mounted on a metallic head which
rotates with a linear speed of 60mm/s. The respirators are
passed within 20mm of the tip of an 800oC (±50oC) propane
burner ame. The respirator shall not burn or continue to burn
within 5 seconds of removal from the ame.

– Suitable for the application;
– Fitted correctly;
– Worn during all periods of exposure;
– Replaced when necessary.
ŔProper selection, training, use and appropriate
maintenance are essential in order for the product to help
protect the wearer from certain airborne contaminants.
Failure to follow all instructions on the use of these
respiratory protection products and/or failure to properly
wear the complete product during all periods of exposure
may adversely aect the wearer’s health, lead to severe or
life threatening illness or permanent disability.
ŔFor suitability and proper use follow local regulations,
refer to all information supplied or contact a safety
professional/3M representative.
ŔBefore use, the wearer must be trained in use of the
complete product in accordance with applicable Health and
Safety standards/guidance.
ŔThese products do not contain components made from
natural rubber latex.
ŔThese products do not protect against gases/vapours.
ŔDo not use in atmospheres containing less than 19.5%
oxygen. (3M denition. Individual countries may apply their
own limits on oxygen deciency. Seek advice if in doubt).
ŔDo not use for respiratory protection against atmospheric
contaminants/concentrations which are unknown or
immediately dangerous to life and health (IDLH).
ŔDo not use with beards or other facial hair that may
inhibit contact between the face and the product thus
preventing a good seal.
ŔLeave the contaminated area immediately if:
– Breathing becomes dicult.
– Dizziness or other distress occurs.
ŔFor single shift use or reusable devices: Discard and replace
the respirator if it becomes damaged, breathing resistance
becomes excessive or at the end of the shift*.
*The respirators are re-usable and can be cleaned and used
for more than one shift.
ŔNever alter, modify or repair this device.
ŔBefore initial use, always check that the product is within
the stated shelf life (use by date).
Fitting Instructions
See Figure 1.
Before tting device, ensure hands are clean.
All respirator components should be inspected for damage
prior to each use.
1. Thread top elastic strap through top buckles. Repeat for
bottom strap and buckles.
2. Hold respirator under chin, with nosepiece up.
3. Locate the upper strap across the crown of the head and
the lower strap below the ears. Straps must not be twisted.
4.
4A. Adjust tension: Increase - pull evenly on both ends of the
top/bottom straps.
4B. Adjust tension: Decrease - without removing respirator,
push out on the back of the buckles.
5.
5A. Ensure face seal is properly formed around the nose.
5B. The face seal must not be folded in.
6. The seal of the respirator on the face should be t-
checked before entering the workplace.
Fit Check
1. Cover the front of the respirator with both hands being
careful not to disturb the t of the respirator.
2. VALVED respirator - INHALE sharply.
3. If the air leaks around the nosepiece, re-adjust the
respirator and face seal upon the face to eliminate leakage.
Repeat the t check.
4. If air leaks at the respirator edges, adjust the tension of the
straps to eliminate the leakage. Repeat the above t check.
If you CANNOT achieve a proper t DO NOT enter the
hazardous area. See your supervisor.
Users should be t tested in accordance with national
requirements. For information regarding t testing
procedures, please contact 3M.
