KleenGuard 3400 FAQ
Is the KleenGuard 3400 (RA3415V) NIOSH-approved?
Yes — a NIOSH N95 under 42 CFR Part 84, 95% minimum non-oil filtration.
KleenGuard 3400 vs 3300 — what is the difference?
The 3400 adds an exhalation valve for cooler breathing; the unvented 3300 is for source control. Same N95 protection.
What does the valve on the KleenGuard 3400 do?
It vents warm, moist exhaled air to reduce heat and fogging; inhaled air is still filtered. It does not change the N95 level.
Can you reuse the KleenGuard 3400?
Single-use with limited reuse when constrained; discard when soiled, damaged, or hard to breathe through. See can you reuse an N95?.
Does the KleenGuard 3400 require fit testing?
Yes for OSHA-regulated use — medical evaluation, annual fit test, and seal check per OSHA 29 CFR 1910.134.
Can I wear the KleenGuard 3400 with a beard?
No — facial hair across the seal fails the fit test; clean-shaven along the seal is required, or use a PAPR.
Is the KleenGuard 3400 good for wildfire smoke?
Yes — a well-fitted N95 is the standard for smoke particulates; ensure a clean-shaven seal. It does not remove gases.
Does the KleenGuard 3400 protect against oil?
No — N95 is non-oil; use R95 or P100 for oil mist.
Is the KleenGuard 3400 good for silica?
An N95 is the NIOSH minimum for silica with controls under OSHA 1926.1153; step to P100 for high exposure. See silica dust respirators.
How long does the KleenGuard 3400 last?
No fixed hours — replace at end of task or when dirty, damaged, or breathing resistance rises.
Is the KleenGuard 3400 a surgical N95?
No — it is an industrial N95 without FDA clearance. See surgical N95 respirators.
What does the KleenGuard 3400 NOT protect against?
Oil mist, gases and vapors, asbestos, low-oxygen atmospheres, and anything needing more than 95% filtration.
Can the KleenGuard 3400 be used for source control?
No — the valve releases unfiltered breath. Use the unvented 3300 Series there.
Who makes the KleenGuard 3400?
KleenGuard is the industrial PPE brand of Kimberly-Clark Professional.
Is the KleenGuard 3400 good for hot weather?
Yes — the exhalation valve vents heat, making it more comfortable than an unvented cup on warm jobs.
