High Efficiency (HE) Particulate Filter, Pre-filter and Spark Arrestor
NOTE: The high efficiency (HE) filter, pre-filter and spark arrestor must always be used. The pre-filter is designed
to extend the service life of the HE filter by capturing many of the larger particles. The spark arrestor is a metal screen.
Inspect the spark arrestor each time the filters are changed. If it is dirty, remove it and clean with a solution of clean
water and mild detergent. Dry the spark arrestor with a clean cloth and ensure the spark arrestor is completely dry before
reinstalling. If the spark arrestor is damaged, replace with a new spark arrestor. The HE filter and pre-filter CANNOT be
cleaned; do not attempt to remove contamination from the HE filter or pre-filter using compressed air or other means.
Always correctly use and maintain the filter assembly. Failure to do so may reduce respirator performance, overexpose
you to contaminants, and may result in sickness or death.
a. Inspect filter and filter seal before each use and immediately replace if damaged.
b. Do not press on the filter grill when installing the filter into the filter cover. This may result in damage to the filter
membrane allowing hazardous particles to enter the breathing zone.
c. Keep filter seal clean.
d. Never attempt to clean filters by knocking or blowing out accumulated material. This may result in damage to the
filter membrane allowing hazardous particles to enter the breathing zone.
The filter-loading indicator reflects particle clogging only. It does not provide any information about gas & vapor service
life. Attempting to use the filter loading indicator for gases and vapors may result in sickness, or death.
The nuisance odor pad should only be used for concentrations of organic vapors not exceeding the OSHA permissible
exposure limit (PEL) or applicable government occupational exposure limits, whichever is lower. Replace if smell or
taste is detected. Use of the nuisance pad for concentrations exceeding applicable exposure limits may result in
sickness or death.
The service life of the optional organic vapor/acid gas cartridge must be pre-determined before use. The organic
vapor/acid gas cartridge must be replaced according to an established change-out schedule, regulations, or sooner if
smell, taste, or irritation from contaminants is detected. Failure to do so may result in sickness or death.
Do not use the 3M™ Adflo™ PAPR system with a heavily loaded spark arrestor or without the spark arrestor screen
properly installed. Exposing a heavily loaded spark arrestor, or filter assembly to direct contact with sparks or molten
metal spatter may damage the filter, allowing unfiltered air into the breathing zone, which may result in sickness or
death, and may cause the filter or blower housing to ignite, resulting in serious injury, sickness or death.
1. Inspect the HE filter to be installed. Make sure:
• Filter material is intact and dry with no tears or other damage.
• Filter gasket is present and intact with no particulates, cuts, distortions or indentations. Wipe gasket with clean,
dry cloth, if dirty. Dispose and replace filter if damage is noted.
2. Remove the filter cover (Fig. 4).
3. Place the spark arrestor, pre-filter and HE filter into the filter cover, ensuring that the ribs on the HE filter are aligned
with the slots on the latch side of the filter cover (Fig. 5). Ensure all are squarely seated in the filter cover. Do not press
on the filter grill when installing the filter into the filter cover (Fig 6).
4. To reinstall the filter cover in the 3M™ Adflo™ PAPR, hook the left side of the filter cover into the left side of the 3M™
Adflo™ PAPR. Press down on the right side of the cover until the catch fully engages with an audible click.
Install the 3M™ Adflo™ PAPR Organic Vapor/Acid Gas (OV/AG) Cartridge or Nuisance
Odor Pad Assembly
The 3M™ Adflo™ PAPR has a "stackable" chemical cartridge capability that helps provide protection from certain organic
vapors and acid gases and a "stackable" nuisance odor pad assembly to help reduce nuisance odors and nuisance ozone.
NOTE: Nuisance odor refers to concentrations of organic vapors not exceeding the OSHA permissible exposure limit (PEL)
or applicable government occupational exposure limits, whichever is lower.
NOTE: The OV/AG cartridge and nuisance odor pad assembly must always be used with the HE filter, pre-filter and spark
arrestor. Do not use the OV/AG cartridge or nuisance odor pad assembly alone or in combination with one another.
1. Remove the filter cover as noted above (Fig. 4).
2. Inspect the HE filter to be installed. Make sure:
• Filter material is intact and dry with no tears or other damage.
• Filter gasket is present and intact with no particulates, cuts, distortions or indentations. Wipe gasket with a clean,
dry cloth, if dirty. Dispose and replace filter if damage is noted.
3. Inspect the filter cover, the pre-filter and the spark arrestor. Replace as needed (Fig. 5, 6).
4. Inspect the OV/AG cartridge or nuisance odor pad assembly to be installed. Make sure:
• Gasket is present and intact with no particulates, cuts, distortions or indentations. Wipe gasket with a clean, dry
cloth, if dirty. Dispose and replace if damage is noted
5. Place the spark arrestor, pre-filter and HE filter into the filter cover, ensuring that the ribs on the HE filter are aligned
with the slots on the latch side of the filter cover (Fig. 5). Ensure all are squarely seated in the filter cover. Do not press
on the filter grill when installing the filter into the filter cover (Fig 6).
6. Hook the left side of the OV/AG cartridge or nuisance odor pad assembly into the left side of the PAPR and press the
cartridge down until its catch engages with an audible click (Fig. 7).

(Fig 8).
Replacement of the Nuisance Odor Pad
The nuisance odor pad may be replaced by pressing the expired nuisance odor pad out of the nuisance odor pad assembly
from the backside, or side with the gasket or multiple square holes. It is easiest to press the nuisance odor pad out on
the vertical edges, nearest to the frame edge, and then work the entire nuisance odor pad free from the assembly. Install
a new nuisance odor pad by pressing it into the nuisance odor pad assembly. The nuisance odor pad may only be used
to help provide relief from concentrations of organic vapors not exceeding the OSHA permissible exposure limit (PEL) or
applicable government occupational exposure limits, whichever is lower. Replace when smell or taste occurs.
Install the Breathing Tube
Select an approved breathing tube for the headgear to be used. Refer to the 3M™ Adflo™ PAPR NIOSH Approval Label for
approved headgear-breathing tube combinations.
NOTE: The SG-50W breathing tube can only be used with 9100 Air, 9100 FX Air, 9100 MP and M-series headgear. The
SG-50W breathing tube must be used when using the 9100 Air or 9100 MP welding helmets with HE filter-OV/AG cartridge
combination and must be used with M-400 headgear when used with any Adflo PAPR configuration.
