3M Versaflo S-133L+5 PAPR Hood Review — General Industry Loose-Fitting Headtop
Is the 3M Versaflo S-133 the right PAPR hood for general-industry use?
Short answer: Yes for general industrial use — the 3M Versaflo S-133 is a loose-fitting PAPR hood that pairs with Versaflo TR-300/TR-600 blowers, offering APF 25 protection without a face seal or fit test, suitable for dust, fume, and light-chemical environments.
3M Versaflo S-133L+5 PAPR Hood Review (2026)
The 3M Versaflo S-133 sits at the entry tier of the Versaflo PAPR hood ecosystem — a loose-fitting hood designed for general industrial use with TR-300 and TR-600 blowers. Buyers choosing between S-series hoods are typically deciding on coverage level (hood length), visor size, and whether sealed-collar comfort matters for their application. This review covers the S-133 within the S-series and how it compares to the S-433 and economy S-403. Selection context is in our 3M Respiratory Protection Buyer's Guide.
Editorial verdict — 4.3/5
The 3M Versaflo S-133L earns 4.3/5 as a clean, practical general-industry PAPR hood: loose-fitting (no fit test), standard visor, and compatible with the full Versaflo TR blower range. Choose the S-433 for a larger visor; choose the S-403 for economy quantity packs.VIEW ON WC SAFETY →CHECK PRICE ON AMAZON →

Who it is for
- General-industry workers running 3M Versaflo TR-300 or TR-600 blowers who need a standard PAPR hood with clear visor
- Beard wearers who cannot seal a half-mask or full-face respirator — see our beard PAPR guide
- Safety managers choosing between S-133, S-433, and S-403 for their PAPR fleet
What the S-133L+5 does well
No fit test, no seal dependency
The S-133 is a loose-fitting hood — OSHA APF 25 without a quantitative fit test. This is the core advantage of PAPR hoods over tight-fitting facepieces: no facial hair restrictions, no seal-check dependency, reduced training burden. See fit-testing context and beard PAPR use.
Clear visor for situational awareness
The S-133 visor provides a clear field of view, relevant in industrial environments where peripheral visibility matters for safety. Tinted or coated visor versions are available for high-brightness welding-adjacent applications.
Versaflo ecosystem compatibility
The S-133 is part of the 3M Versaflo S-series hood ecosystem — all S-series hoods connect to the same Versaflo TR blower line (TR-300 and TR-600). Industrial programs that standardize on the Versaflo blower platform can add S-series hoods as task-specific headtops without buying a new blower per headtop.
Where the S-133L+5 falls short
APF 25 for loose-fitting hood
Environments requiring APF above 25 need a tight-fitting Versaflo facepiece with a fit-tested seal. The S-133, like all loose-fitting S-series hoods, is limited to APF 25 per OSHA 1910.134.
Requires a separate Versaflo blower
The S-133 is a headtop only — it requires a compatible Versaflo TR-300 or TR-600 blower to function. It is not a self-contained PAPR.

When to step up from the S-133L+5
Want a larger visor? The 3M Versaflo S-433L offers expanded facial coverage. Need economy bulk packs? See the S-403S+20. For an added inner collar for extended coverage, see the S-655 collar accessory. For the Drager alternative, see the Drager X-plore 8500 with long hood or short hood.
Category context
The 3M Versaflo S-series hoods are the consumable headtop layer in the Versaflo PAPR platform — the blower is the capital item, the hoods are the application-specific headtops. S-133 is the standard entry hood; S-433 adds a larger visor; S-403 is the economy/volume pack; S-655 adds a sealed inner collar for extended coverage. Selecting the right hood tier depends on visor area preference, task duration, and whether neck/collar sealing matters. See our respirator sizing guide for fit context.
Total cost of ownership
Hood replacement frequency depends on soiling, physical damage, and your program's replacement protocol. The S-133 is priced for periodic headtop replacement — many programs replace hoods per campaign or per defined interval rather than only at failure.
Final verdict
The 3M Versaflo S-133L+5 earns 4.3/5 — a solid general-industry PAPR hood for Versaflo TR blower programs. Choose the S-433 if you want a wider visor, the S-403 for economy packs, or the S-655 when you need added collar coverage.

S-133L+5 FAQ
What PAPR blower is the 3M Versaflo S-133 compatible with?
The S-133 is compatible with 3M Versaflo TR-300 and TR-600 series PAPR blowers. It is not compatible with non-Versaflo PAPR platforms unless tested and approved.
Does the 3M Versaflo S-133 require fit testing?
No — the S-133 is a loose-fitting hood (APF 25) that does not require a quantitative fit test per OSHA 1910.134.
What APF does the 3M Versaflo S-133 provide?
APF 25 per OSHA Table 1 to 1910.134(d)(3)(i)(A) for loose-fitting PAPR hoods.
S-133 vs S-433 — what is the difference?
The S-433 features a larger visor providing greater facial coverage; the S-133 has a standard visor. APF and blower compatibility are the same. Choose S-433 for maximum face visibility.
S-133 vs S-403 — what is the difference?
The S-403S+20 is an economy quantity pack of a similar loose-fitting PAPR hood. The S-133 is a standard 5-pack. Choose S-403 for high-volume consumption programs.
Can I use the S-133 with a beard?
Yes — the S-133 is a loose-fitting hood with no face seal requirement, making it suitable for beard wearers. See our beard PAPR guide.
Is the 3M Versaflo S-133 reusable?
Yes — the S-133 is designed for reuse with regular inspection. Replace when the visor is scratched or damaged, the hood material is compromised, or per your facility's replacement protocol.
What hazards does the 3M Versaflo S-133 protect against?
Protection depends on the filter/cartridge installed in the Versaflo blower. The hood itself is the headtop — the blower and filter determine the hazard coverage.
Is the S-133 suitable for welding?
Standard S-133 visor is clear — not suitable for arc welding (requires a welding headtop with appropriate shade lens). For general welding-adjacent environments (grinding dust, fume), the S-133 with HEPA filter is applicable.
What is the S-655 inner collar and does the S-133 need it?
The S-655 is a separate inner collar accessory that extends the coverage at the neck/shoulder interface. The S-133 does not include this collar; add the S-655 when task conditions require an extended neck seal.
How do I clean the 3M Versaflo S-133?
Follow 3M's cleaning procedure for S-series hoods — the visor and hood fabric have specific care requirements. Avoid solvents on the visor; wipe with approved cleaning solutions per the 3M S-series maintenance guide.
S-133 vs Drager X-plore 8500 hood — which PAPR headtop?
The S-133 runs on 3M Versaflo TR blowers; the Drager long and short hoods run on Drager X-plore 8500 blowers. Headtop choice is determined by your blower platform — they are not interchangeable.
What size is the 3M Versaflo S-133L+5?
The 'L' in S-133L denotes the large/standard size. '+5' refers to the pack quantity (5 hoods per case). Confirm sizing against 3M's current S-133 documentation.
Does the S-133 work for asbestos abatement?
With HEPA-level filters in the Versaflo blower, the S-133 hood provides the particulate protection class for asbestos. Confirm regulatory requirements per OSHA 1926.1101 for your specific application.
Where can I find 3M Versaflo S-133 replacement hoods?
Via the Amazon link above or through our PAPR accessories catalog. See S-403 economy packs for bulk quantities.
