MSA 818342 P100 Flexi-Filters, 2-Pack
MSA 818342 P100 Flexi-Filters are replacement particulate filters for approved MSA Advantage respirator configurations. This pack contains two filters. Their flexible, low-profile shape and swept-back position help preserve the wearer's field of view and provide clearance around other PPE. Choose this particulate-only model when the exposure assessment calls for P100 filtration without gas or vapor protection.
Key Features
- P100 filtration: For oil and non-oil particulate aerosols within the approved system's limitations.
- Low profile: Helps accommodate welding hoods and other PPE, subject to a clearance check.
- Swept-back shape: Keeps the filters closer to the facepiece and away from the forward viewing area.
- Flexible pads: Provide an alternative form to rigid particulate filter cartridges.
- Replacement pair: Supplies two matching filters for the respirator configuration.
Applications
Consider these filters for assessed particulate exposures during sanding, grinding, surface preparation, and industrial maintenance.
Welding applications require evaluation of the metals, coatings, gases, and ventilation involved. A particulate filter does not remove welding gases.
For painting preparation, distinguish sanding dust from solvent vapors or spray hazards. Select the appropriate cartridge, combination filter, or supplied-air equipment when the process requires additional protection.
Compatibility and Selection
Check that a hood or face shield does not press against the filters or disturb the respirator seal during normal head movement. Filter shape can help with clearance, but it cannot guarantee fit with every accessory.
Confirm the exact Advantage facepiece and approved filter combination before ordering. The MSA brand name alone does not establish compatibility with every respirator or cartridge attachment.
Review the MSA manufacturer filter chart for the 818342 part identification and differences between Flexi-Filter models. This historical chart supplements the current approval label and instructions supplied with your respirator.
Compare respirator cartridges and filters when the task includes gases or vapors.
FAQ
Does 818342 remove nuisance odors?
No nuisance-odor capability is listed for this model. MSA identifies separate Flexi-Filter part numbers for nuisance organic vapor, ozone, or acid gas applications.
Does P100 mean unlimited service life?
No. Follow MSA replacement instructions and applicable time limitations. Leave the exposure area if breathing becomes difficult or the filters become damaged.
Are P100 filters enough for asbestos work?
The P100 rating alone does not authorize an asbestos task. Required respiratory protection depends on exposure, work classification, and applicable regulations. Some operations require powered or supplied-air equipment. Have the complete respirator selection determined through the employer’s asbestos protection program before work begins.
