3M Versaflo TR-6820N HEPA/Nuisance OV Filter 5-Pack for TR-600/TR-800

The 3M Versaflo TR-6820N HEPA and Nuisance OV Filter is a 5-pack of replacement filters for the 3M Versaflo TR-600 and TR-800 PAPR systems — providing HEPA-level 99.97% minimum particulate filtration alongside nuisance-level organic vapor activated carbon in a single filter for operations with heavy particulate loads and incidental organic vapor exposure in environments where nuisance-level odor reduction is beneficial but full organic vapor cartridge protection is not the primary respiratory protection requirement. The TR-6820N's HEPA particulate filtration addresses the full range of airborne particulate hazards — fine dust, biological aerosols, welding fume, metal particulate, pharmaceutical powder, and other submicron particles at HEPA efficiency — while the integrated activated carbon layer provides nuisance-level reduction of organic vapors that accompany many industrial particulate operations. The distinction between nuisance OV and full OV cartridge protection is critical for correct selection: the TR-6820N's carbon component is appropriate for nuisance odor control in operations where organic vapor concentrations are low and the primary hazard is particulate, not for operations where measured OV concentrations approach or exceed OSHA PEL/action levels. For those environments, the TR-6510N OV/HE cartridge or TR-6530N OV/Acid Gas/HE cartridge provides the full organic vapor adsorption capacity required for OSHA-compliant vapor protection. The TR-6820N is the appropriate choice for environments where HEPA particulate filtration is the primary protection need and organic vapor odors are a nuisance-level comfort concern rather than a documented overexposure hazard.

3M Versaflo TR-6820N HEPA/Nuisance OV Filter — Key Features

• HEPA particulate filtration — 99.97% minimum efficiency for fine dust, biological aerosol, and submicron particulate
• Nuisance OV activated carbon — odor reduction for incidental organic vapor exposure
• Compatible with TR-600 and TR-800 PAPR systems
• 5-pack — efficient replacement supply for HEPA PAPR programs
• Not rated for full OV protection — for nuisance odor only, not measured OV overexposures

Specifications

HEPA vs. HE Filtration: What HEPA Means in PAPR Context

In PAPR filter terminology, HEPA (High Efficiency Particulate Air) and HE (High Efficiency) refer to the same 99.97% minimum particulate filtration efficiency standard when applied to NIOSH-approved PAPR systems. The TR-6820N's HEPA designation aligns with the HEPA standard for particulate capture efficiency, providing equivalent particulate protection to HE-rated filters at the 99.97% minimum efficiency level for 0.3-micron test particles. HEPA-level filtration is appropriate for the most demanding particulate environments: pharmaceutical manufacturing with API powder and aerosol exposure, healthcare operations with biological aerosol risk, metal powders and fine welding fume, laboratory biological work, and any operation where submicron and ultrafine particulate capture is required. The addition of nuisance OV activated carbon in the TR-6820N provides useful comfort benefits in lightly contaminated organic vapor environments — reducing detectable odors from solvents, coatings, and organic process chemicals present at nuisance concentrations — without replacing the full service-life OV protection that a cartridge like the TR-6510N or TR-6530N provides when OV concentrations constitute a measured overexposure hazard.

Compliance and Certifications

• NIOSH — HEPA particulate filtration for NIOSH-approved 3M Versaflo TR-600/TR-800 PAPR
• OSHA 29 CFR 1910.134 — respiratory protection standard; written program required for mandatory PAPR use

Real-World Benefits

HEPA filtration provides maximum particulate capture efficiency for pharmaceutical, healthcare, and fine particulate industrial operations. Workers in pharmaceutical API manufacturing, healthcare settings with biological aerosol exposure, and high-particulate industrial operations receive HEPA-level protection from the TR-6820N's filter media — the same 99.97% efficiency standard applicable to the highest-demand particulate applications.

Integrated nuisance OV carbon reduces organic odors in light-vapor environments without requiring a separate cartridge change schedule for full OV protection. Operations where incidental organic vapors generate detectable odors at nuisance levels — but where measured OV concentrations are well below OSHA action levels — benefit from the nuisance carbon's odor reduction without the change schedule management overhead of a full OV cartridge program.

Applications and Use Cases

• Pharmaceutical manufacturing — API powder and aerosol handling — TR-6820N for PAPR-equipped pharmaceutical production workers in API weighing, blending, and granulation operations with fine pharmaceutical powder and organic solvent odors at nuisance concentrations
• Healthcare and laboratory biological operations — HEPA PAPR for healthcare workers and laboratory personnel in biological aerosol environments where HEPA-level filtration is indicated alongside incidental chemical odors
• Industrial operations with fine particulate and incidental organic vapor odor — combined HEPA + nuisance OV for production workers in environments with heavy fine particulate and ambient organic vapor odors at nuisance-level concentrations

Frequently Asked Questions

Can I use the TR-6820N as an organic vapor cartridge for operations above the OSHA OV action level?

No. The TR-6820N's activated carbon component provides nuisance-level organic vapor reduction only — it is not rated or tested for OV service life at OSHA action level or PEL concentrations, and does not provide a cartridge change schedule basis for operations with measured OV overexposure. For operations where measured organic vapor concentrations approach or exceed OSHA action levels, specify the TR-6510N (OV/HE) or TR-6530N (OV/Acid Gas/HE), which carry full OV cartridge ratings and support the change schedule requirements of OSHA 1910.134. Using a nuisance OV filter in place of a full OV cartridge where measured overexposures exist creates a respiratory protection gap in your OSHA compliance program.
