Deciding between a respirator parts lot and a complete hard hat with face shield isn't as simple as comparing two similar products. The real question is what your job site requires today. If you're maintaining older Willson respirators, a source of original facelets can be exactly what keeps them from being retired. If you need head and face protection for general industrial work, a ready-to-wear hard hat with a mounted shield does the job without assembly. That's the trade-off between the RARE WILLSON Respirator FACELET LOT and the Blue HexArmor Hard Hat with Full Face Shield. Both are workplace safety buys, but they serve very different needs. The choice isn't about which is better overall; it's about which one matches the task you're preparing for.
Quick verdict
The RARE WILLSON Respirator FACELET LOT is the right pick for maintaining classic Willson respirators. The Blue HexArmor Hard Hat with Full Face Shield is the right pick for ready-to-wear head and face protection. Priced at USD 99.99 and USD 50.00, the HexArmor is the cheaper, more immediate option.
Side-by-side comparison

|---|---|---|
| Price | USD 99.99 | USD 50.00 |
| Condition | New - Open box | Used |

| Best match | Classic Willson respirator owners | Immediate head-and-face protection |
Where each product wins
The Willson lot wins on parts coverage. It bundles Style No. 2 facelets and part number 20-20931, with compatibility across many classic Willson respirator series. If you already own one of those respirators, this lot gives you a single source for spares. For respirator owners, the Willson lot is the difference between shelving a unit and keeping it in active rotation. The HexArmor wins on speed and simplicity. It's a complete hard hat and full face shield in one unit, ready to put on when you get to the job site. You don't need to find a separate shield, mount hardware, or additional components. For general job sites, the HexArmor is the difference between a slow assembly process and walking straight onto the floor.
Product notes
RARE WILLSON Respirator FACELET LOT

Choose this lot if you maintain classic Willson respirators. It comes as New - Open Box, meaning it's vintage new old stock in five original boxes, with Style No. 2 facelets and part number 20-20931. The NOS designation means these facelets are unused, so they're closer to new old stock than to salvaged parts. The facelets are compatible with a long list of Willson respirator series, including the 1B, 2B, 5D, 6, 11B, 22B, 45D, 55, 400, and 750DC. For someone restoring or repairing those respirators, this is a rare source of original spares. The limitation is that you're getting facelets, not a complete respirator, and the open-box state means the packaging shows previous handling.
Blue HexArmor Hard Hat with Full Face Shield

Go with this unit if you need a hard hat and face shield that work together right away. The shield is mounted to the hat and has a scratch-resistant coating, so you can wear it straight off the rack. The blue shell and full shield cover both head and face, and the hat-mounted suspension keeps everything in place without a separate bracket. It's a straightforward choice for a worker who wants one piece of gear for the head and face. The clear drawback is the used condition: you're getting a pre-owned unit rather than a factory-sealed product, so you'll want to give it a quick inspection before relying on it for critical protection.
Final choice by use case
Choose the RARE WILLSON Respirator FACELET LOT if you already own one of the compatible Willson respirators (1B, 2B, 5D, 6, 11B, 22B, 45D, 55, 400, or 750DC) and need original facelets to keep it in service. Choose the Blue HexArmor Hard Hat with Full Face Shield if you need a complete head-and-face protection solution today. Both are purpose-driven PPE lots, but they solve different problems.
