Hazard Coverage — Moldex 4400P100 AirWave P100 Respirator — SmartStrap + Valve

The Moldex 4400P100 AirWave P100 Respirator — SmartStrap + Valve is NIOSH-approved under 42 CFR 84 as a P100 respirator: ≥99.97% filtration (P100), oil-proof with no time restriction on oil aerosol exposure. Appropriate for lead dust abatement, asbestos fiber removal, hexavalent chromium from stainless welding, heavy oil mist, and any application requiring maximum particulate filtration. Browse all P100 disposable respirators.

Unlike N-class and R-class, the P-class has no oil-exposure time limit. Discard when breathing resistance increases or when soiled. Read our N95 vs P100 guide.

Frequently Asked Questions

What does the exhalation valve on the 4400P100 do?

The exhalation valve opens when you breathe out, allowing warm humid air to exit directly rather than passing back through the filter media. This reduces heat and moisture buildup inside the mask — a significant comfort advantage during extended or physically demanding wear. Inhalation closes the valve, so all inhaled air is filtered normally.

Does the valve on the 4400P100 reduce filtration efficiency?

No. The exhalation valve does not affect inhalation filtration efficiency — the 4400P100 still filters inhaled air at the rated N95/R95/P100 level. The valve only controls exhaled air routing. Note: because exhaled air is not filtered, valved respirators are not appropriate as source-control devices (e.g., in surgical environments or when protecting others from the wearer).

Is a valved respirator like the 4400P100 acceptable for source control?

No. A valved respirator directs exhaled air outward unfiltered and is not appropriate where the wearer must also protect others (surgical settings, some healthcare environments). Facility policies may prohibit valved masks in sterile or at-risk patient areas. For source-control requirements, use an unvalved N95 or a surgical N95.

What does P100 mean for the 4400P100?

P100 is the highest NIOSH particulate classification: ≥99.97% filtration efficiency, oil-proof (unlike R-series which is oil-resistant for one shift only). The 4400P100 provides maximum particulate filtration with no time restriction on oil aerosol exposure. Compare classes in our N95 vs P100 guide.

Is the 4400P100 NIOSH-approved?

Yes. The 4400P100 holds NIOSH P100 approval under 42 CFR 84 Subpart K. Confirm the TC approval number on the NIOSH Certified Equipment List using the model number printed on the mask.

What hazards is the 4400P100 rated for?

The 4400P100 is rated for oil-proof particulates at ≥99.97% efficiency — covering lead dust, asbestos fibers, hexavalent chromium, heavy oil mist, paint overspray, and fine metallic particulates. Browse all P100 disposable respirators.

Does the 4400P100 require a fit test?

Yes. OSHA 29 CFR 1910.134 requires fit testing before first use in any workplace respiratory protection program. See our fit testing guide for qualitative (BitrexTM/saccharin) and quantitative options for half-face disposable designs.

Can the 4400P100 be used for lead abatement?

Yes, the P100 filter class is commonly specified for lead dust and paint chip abatement work. OSHA's lead standard (29 CFR 1910.1025) specifies a minimum APF 10 (half-face) for many lead operations. A properly fitting P100 disposable meets this requirement; verify with your site's industrial hygienist.

How long does the 4400P100 last in oil mist environments?

Unlike the R95 class (one shift limit), the P100 class has no time restriction on oil aerosol exposure. Discard the 4400P100 when breathing resistance increases noticeably, when the mask is damaged or soiled, or per your employer's change-schedule program.

Does the 4400P100 filter vapors and gases?

No. The 4400P100 is a particulate filter only — it does not capture organic vapors, acid gases, or other chemical vapors. For combined particulate + vapor protection, you need a half-face or full-face respirator with combination cartridges. See our respirator selection guide.

How does the 4400P100 compare to N95 masks?

The 4400P100 (P100) filters 99.97% of particles and is oil-proof; an N95 filters 95% and has no oil resistance. Step up to the 4400P100 for lead, asbestos, heavy oil mist, or any application where an N95's 95% baseline isn't sufficient or where oil aerosols are present. Browse N95 masks for lighter-duty comparison.

Is the 4400P100 reusable?

The 4400P100 is a disposable respirator — discard after use per manufacturer guidance. Do not wash or attempt to decontaminate a disposable P100; the filter media and structural integrity cannot be verified after washing.
