WC Safety Editorial Pick: The S-433S-5 is the small/medium version of 3M's best-fit Versaflo hood — if your workers need a large, order the S-433L-5; if they need S/M, this is the one. Don't let workers wear an oversized hood; proper fit is required for PAPR protection levels to hold.
The 3M Versaflo S-433S-5 is the small/medium size variant of the S-433 premium hood with integrated head suspension — functionally identical to the S-433L but sized for workers with smaller head circumferences. Proper hood sizing is not cosmetic: an oversized PAPR hood can shift out of position during work, and the visor dropping or twisting compromises both visibility and the neck-and-shoulder coverage that the hood is designed to provide. The S-433S-5 delivers the same suspension-equipped, stable-fit design as the large version in a size matched to S/M headforms.
The 5-pack format makes the S-433S-5 practical for facilities with mixed-size workforces. If your team includes workers who need both large and small/medium hoods, maintain separate inventory of S-433L-5 and S-433S-5 to ensure correct fit for each worker. The hoods are otherwise identical in construction, compatibility, and coverage — only the internal sizing differs. All S-433 hoods connect to Versaflo TR-300, TR-300N+, TR-600, and TR-800 series motor units via the BT-30 breathing tube.
Facility safety managers should include hood size verification in their PAPR fit assessment process. OSHA's respiratory protection standard (29 CFR 1910.134) requires that employers select respirators that properly fit workers. For loose-fitting hoods like the Versaflo S-series, NIOSH specifies a fit check procedure in the user instructions that confirms adequate seal and coverage. Providing both S/M and Large size options ensures workers can be properly equipped regardless of headform.

Frequently Asked Questions
What is the difference between S-433S and S-433L?
S-433S is the small/medium size; S-433L is the large size. The hoods are identical in construction and features — only the internal sizing differs. Confirm worker head size before ordering.
How do I know if my worker needs the S or L size?
Use 3M's Versaflo sizing guide, which provides head circumference measurements to match each worker to the S (small/medium) or L (large) size. Do not guess — proper hood sizing is a PAPR program requirement.
How many hoods are in the S-433S-5?
Five hoods per pack.
Which motors work with the S-433S-5?
All 3M Versaflo TR-series motors: TR-300, TR-300N+, TR-600 (all variants), and TR-800 (including intrinsically safe versions).
Does the S-433S include the breathing tube?
No. The BT-30 breathing tube is sold separately and is required to connect the hood to the PAPR motor.
Is the S-433S appropriate for pharmaceutical clean rooms?
Yes. The low-linting S-433 fabric is used in pharmaceutical and medical device manufacturing. Confirm cleanroom classification requirements with your facility's environmental monitoring program.
How often should I replace the S-433S hood?
Replace when visually contaminated, physically damaged, or per your facility's scheduled replacement program. For high-exposure environments, weekly replacement is common.
Can the S-433S be used with the TR-800 intrinsically safe PAPR in hazardous locations?
Yes. The S-433S is compatible with the TR-800 series intrinsically safe motors, enabling PAPR use in Zone 1 and Zone 2 classified environments when required.
Is the S-433S NIOSH approved?
The S-433S is part of the NIOSH-approved 3M Versaflo PAPR system when used with an approved motor unit and filter combination.
What breathing tube do I need for the S-433S?
The S-433S uses the 3M Versaflo BT-30 breathing tube, sold separately.
Is there a difference in coverage between the S and L size hoods?
No. The S-433S and S-433L provide identical coverage areas — head, face, neck, and shoulders. Only the internal sizing differs to match the headform of the wearer.
How does the head suspension in the S-433S adjust?
The integrated suspension includes an adjustable headband that can be sized within the small/medium range. Adjust until the hood sits securely without shifting during work — the visor should remain centered in the field of vision.
