KleenGuard 3400 Series N95 Particulate Respirator (RA3415V)

The KleenGuard 3400 Series RA3415V is a molded cup-style N95 particulate respirator with exhalation valve — NIOSH-approved under 42 CFR Part 84, rated at 95% minimum filter efficiency against non-oil-based particles. The 3400 series represents KleenGuard's updated cup respirator platform relative to the 3300 series, with the RA3415V designation indicating the valved configuration in a regular-fit cup. Available in a 10-respirator box, the RA3415V is currently out of stock on Amazon; pricing reflects the comparable 3300V (54626) listing at $22.89 per 10-box. For in-stock N95 alternatives, see the disposable respirators collection.

Construction and Design

The RA3415V molded cup uses a rigid shell that maintains filter media position and face standoff regardless of humidity and breathing load — the standard structural benefit of cup-style over flat-fold N95 designs. The exhalation valve routes exhaled air out of the cup without passing through the N95 filter media, reducing exhalation breathing resistance and internal heat and moisture accumulation during sustained wear. A two-strap headband distributes retention across crown and nape; an adjustable noseclip provides the nose-bridge seal required for proper N95 fit. The 3400 series cup geometry represents KleenGuard's current-generation design versus the 3300 series, with refinements to seal surface and interior comfort relative to the earlier RA3315V platform.

Compliance and Ratings

The KleenGuard 3400 RA3415V is NIOSH-approved under 42 CFR Part 84, N95 class. OSHA 29 CFR 1910.134 and 29 CFR 1926.103 medical evaluation, fit test, and written respiratory protection program requirements apply before workers use tight-fitting N95 respirators. The exhalation valve is a compliance consideration: exhaled air is not filtered through the N95 media, making the RA3415V inappropriate for environments requiring source control of exhaled particles — surgical settings, aseptic manufacturing, and some food processing environments where valved respirators are prohibited. Confirm that valved N95 respirators are permitted under the site respiratory protection program before specifying the RA3415V.

Performance Assessment

The exhalation valve reduces exhalation breathing resistance — operationally significant for workers performing sustained moderate to heavy physical labor in warm or humid environments where exhalation heat buildup is a fatigue and comfort factor. Inhalation filtration is unaffected by the valve; N95 efficiency applies on inhalation through the cup media. The 3400 series cup platform addresses the 3300 series' fit geometry with an updated design, though the filtration standard is identical between generations: both are NIOSH N95 under 42 CFR Part 84. The RA3415V is currently out of stock with no Amazon price listed — this product is imported to maintain catalog coverage and should be treated as a back-order or future restocking item. For current in-stock N95 valved alternatives, see the N95 respirators collection.

Strengths

• NIOSH N95, 42 CFR Part 84 — confirmed 95% minimum filter efficiency against non-oil aerosols
• Exhalation valve — reduces exhalation breathing resistance and heat buildup for high-exertion work in permitted environments
• 3400 series updated cup platform — current-generation KleenGuard cup design with refined seal geometry versus 3300 series
• Two-strap headband and adjustable noseclip — standard cup N95 retention and seal system
• KleenGuard brand — established industrial respiratory protection with NIOSH documentation for compliance records

Limitations

• Currently out of stock — no confirmed availability; price is a placeholder based on the analogous 3300V at $22.89/10-box; verify before ordering
• Exhalation valve restricts use in source-control environments — not appropriate for surgical, aseptic, or food processing settings that prohibit valved respirators
• Fit test required per OSHA 1910.134 — individual seal qualification required regardless of filter rating
• 10/box quantity only — no multi-box or bulk quantity under this listing; for large-crew supply needs, evaluate bulk options in the disposable respirators collection

Recommended Use Cases

When in stock, the KleenGuard 3400 RA3415V is appropriate for construction, renovation, and general industry personnel in environments with confirmed particulate hazards where valved N95 respirators are permitted and exhalation comfort is a specification consideration — grinding, demolition, masonry, and abrasive operations at moderate-to-high physical exertion. Workers in environments prohibiting valved respirators should specify the non-valved equivalent or evaluate non-valved N95 options in the disposable respirators collection. For immediate supply needs, in-stock N95 alternatives are available in the N95 respirators collection.

Verdict

The KleenGuard 3400 RA3415V is an N95 molded cup respirator with exhalation valve — KleenGuard's current-generation valved cup platform — currently out of stock on Amazon. Price shown is a placeholder. When available, it is the correct specification for general industry and construction environments where valved N95 respirators are permitted and exhalation comfort is prioritized.
