Gateway Safety PeakFit 80101 N95 Respirator, Unvented

The Gateway Safety PeakFit 80101 is a molded cup-style N95 particulate respirator — NIOSH-approved under 42 CFR Part 84, unvented, in a 20-respirator box at $20.43 ($1.02 per unit). The PeakFit designation identifies Gateway Safety's contoured cup geometry, engineered to improve facial seal conformance across a range of nose-bridge and cheekbone profiles compared to a standard flat-base cup. No exhalation valve is installed — the 80101 is compliant for environments where valved respirators are restricted.

Construction and Design

The PeakFit 80101 molded cup is constructed with a contoured profile at the nose bridge and lateral seal perimeter, intended to reduce the contact-gap leakage that occurs with standard flat-base cups on faces with pronounced nasal structure or prominent cheekbones. The shell is rigid injection-molded polycarbonate, maintaining its shape under humidity and breathing load. A two-strap headband distributes retention force across the crown and nape; an adjustable noseclip provides the nose-bridge seal required for adequate N95 fit. No exhalation valve is present; exhalation passes through the N95 filter media in the cup wall. The contoured profile is the 80101's primary engineering distinction from the standard TruAir 80301 cup at a similar price tier.

Compliance and Ratings

The Gateway Safety PeakFit 80101 is NIOSH-approved under 42 CFR Part 84 — at least 95% filter efficiency against non-oil-based aerosols. OSHA 29 CFR 1910.134 (general industry) and 29 CFR 1926.103 (construction) require a written respiratory protection program, medical evaluation, and fit testing before workers use tight-fitting respirators. The non-valved construction is acceptable in all standard N95 environments including those requiring source control of the worker's exhaled particles — surgical support, food processing, and aseptic manufacturing settings that prohibit exhalation valves. A contoured cup designation does not substitute for individual fit testing; fit test pass rates may improve with the PeakFit geometry in a diverse workforce, but each worker must qualify individually on this specific make and model before use.

Performance Assessment

The PeakFit contoured cup addresses the most common failure mode in molded cup N95 fit testing: leakage at the nose bridge and lateral cheek interface where a standard flat-base cup does not seat accurately on faces with pronounced facial structure. In a workforce fit-test program, the contoured geometry tends to improve fit test pass rates across a diverse face profile population — an operational benefit that compounds across large crews where each fit test failure requires re-testing with an alternative respirator model. The PeakFit's $1.02/unit cost positions it at a slight premium over basic cup N95 options, reflecting the contoured shell design. Non-valved exhalation means breathing resistance is higher than valved alternatives — the PeakFit 80102V (vented version) is available for environments where exhalation comfort is a priority and valved respirators are permitted. Current stock is available.

Strengths

• NIOSH N95, 42 CFR Part 84 — confirmed 95% minimum filter efficiency against non-oil aerosols
• PeakFit contoured cup — improved facial seal conformance at nose bridge and lateral cheek interface; better fit test pass rates in diverse workforces
• Non-valved — compliant for all N95 environments including those prohibiting exhalation valves
• Two-strap headband and adjustable noseclip — stable retention and seal adjustment
• 20-respirator box at $1.02/unit — crew-level quantity, in stock for immediate procurement

Limitations

• Non-valved increases exhalation breathing resistance — valved alternative (PeakFit 80102V) available in the disposable respirators collection for high-exertion environments where valved respirators are permitted
• Contoured cup improves fit probability but does not guarantee fit — individual fit testing per OSHA 1910.134 is required regardless of shell geometry
• Slight price premium over basic cup options — programs that prioritize per-unit cost minimization over fit consistency should evaluate the TruAir 80301 in the N95 respirators collection

Recommended Use Cases

The Gateway Safety PeakFit 80101 is appropriate for general industry and construction environments where a non-valved N95 is specified and fit test pass rate across a diverse workforce is an operational priority — welding fume, sanding, grinding, demolition dust, and airborne particulate environments. Fit-test programs managing mixed-profile workforces will find the PeakFit geometry reduces fit test failure rates compared to standard cup designs. Environments prohibiting exhalation valves — food handling, clean rooms, surgical support — are correctly served by the non-valved 80101. Workers in oil-mist or chemical hazard environments should evaluate R95 or P100 respirators in the respiratory protection collection.

Verdict

The Gateway Safety PeakFit 80101 delivers NIOSH N95 filtration with a contoured cup shell designed to improve facial seal conformance at $20.43 for 20 units ($1.02/unit). The PeakFit geometry is the primary differentiator from a standard cup N95 at this price point — it improves fit test pass rates in diverse workforces, which is operationally relevant for programs managing large crews through respirator qualification. Non-valved and in stock. For the complete disposable respirator selection, see the disposable respirators collection.
