MSA Flexi-Filters N95 Organic Vapor Pads
MSA Flexi-Filter N95 pads for MSA Advantage series respirators — NIOSH-approved N95 particulate filtration plus nuisance-level organic vapor protection in MSA's flexible pad format. The combination of particulate and nuisance OV protection in one filter is practical for environments with both dust and low-level organic vapor presence that doesn't reach OSHA PEL concentrations.

Application
MSA Advantage respirator users in environments with dust plus low-level organic odor that stays below OSHA PEL concentrations — general manufacturing and light industrial settings.
Buying Guide: Nuisance OV vs. Full OV Cartridge
A nuisance-level OV filter pad is appropriate when organic vapor concentrations are below OSHA NIOSH-recommended exposure levels — the filter reduces odor and low-level vapor discomfort but is not rated for environments where OV concentrations meet or exceed OSHA permissible exposure limits. If your environment has measurable OV concentrations at or above regulatory limits, a full organic vapor cartridge is required. If your environment has occasional low-level organic odors alongside dust, the nuisance OV filter pad is the practical solution.
FAQ - MSA8181347 Filters
What does “nuisance-level organic vapor protection” mean?
These N95 filter pads are formulated to help reduce unpleasant organic vapor odors that are present at levels below OSHA Permissible Exposure Limits (PELs). They are not a replacement for organic vapor cartridges and should only be used where nuisance odors—not hazardous vapor concentrations—are present.
Are these filters suitable for welding applications?
Yes. The low-profile, swept-back design allows the filters to fit comfortably under welding hoods while maintaining a secure respirator face seal. The spark-resistant outer layer also makes them well-suited for welding and grinding environments.
Which respirators are these filters compatible with?
These filter pads are specifically designed for use with MSA Advantage® Flexi-Filters® series air-purifying respirators, ensuring proper fit, balance, and performance.
Can these be used for asbestos abatement?
They are suitable for certain asbestos abatement tasks that require N95 particulate filtration. Always verify site-specific safety requirements and regulatory compliance before use.
Do these filters restrict breathing during long shifts?
No. The low breathing resistance, multi-layer construction is engineered to support all-day comfort while maintaining effective filtration.
How is nuisance OV protection different from a full OV cartridge?
Nuisance OV filters reduce low-level vapor presence and odor; full OV cartridges are rated against specific concentration limits at OSHA PELs. Never substitute a nuisance filter for a rated cartridge in environments where OV concentrations reach regulatory limits.
