Facelets are the first part to wear out on a respirator, and for older Willson models, replacements don't show up very often. That's why this RARE WILLSON Respirator FACELET LOT NOS Industrial PPE 20-20931 400 750DC 800C, priced at USD 99.99, deserves a second look. It bundles vintage New Old Stock facelets in original Willson boxes, aimed at anyone keeping classic 400, 750DC, or other listed Willson series in service.
Quick verdict
Buy this lot if you maintain a Willson respirator on the compatibility list and want a ready stash of matching facelets. The NOS condition means you get original packaging and a scarce part number rather than a modern reproduction. The trade-off is the same vintage status that makes it collectible: it is a specific Style No. 2 facelet for specific classic series, not a universal modern replacement.
Who it suits
This is a good fit for three kinds of buyers: repair technicians who service old industrial respirators, safety officers stocking spare parts for legacy equipment, and collectors of original-box industrial PPE. If you already own one of the compatible Willson respirators, the facelets give you a practical consumable stock at a plausible price.
What stands out
The lot includes five original WILLSON boxes and Style No. 2 facelets under part number 20-20931. It is listed as New Old Stock with an open-box condition, meaning it's authentic inventory that has been sitting in storage rather than assembled for resale. The compatibility list covers a long line of classic Willson respirators, including 1B, 2B, 5D, 6, 11B, 22B, 45D, 55, 400, and 750DC; the title also references the 800C model. With 12 facelets in original packaging, this gives a periodic maintenance supply instead of a single spare.
Meaningful trade-offs
Because the lot is built around one facelet style, you need to match it to your respirator model from the list: 1B, 2B, 5D, 6, 11B, 22B, 45D, 55, 400, 750DC, and 800C as noted in the title. If your respirator isn't one of those, this won't help you. Also, since it's New Old Stock, the facelets may have been stored for years; buyers who intend to use them for live safety applications should handle them carefully and confirm they meet their own workplace requirements. That's a reasonable caution, not a defect in the product.

RARE WILLSON Respirator FACELET LOT NOS Industrial PPE 20-20931 400 750DC 800C

Priced at USD 99.99, this lot is a strong choice for anyone who needs authentic spare facelets for a listed vintage Willson respirator. What stands out is the original-box NOS presentation and the number of facelets included. The obvious limitation is that this is a specific Style No. 2 facelet for a defined compatibility list, so you must already use one of those respirator series.
Bottom line
At USD 99.99, this NOS Willson facelet lot is worth it for the right owner. It solves the very real problem of locating obsolete replacement parts for classic Willson respirators, and it does so with original packaging. Buy it for a listed respirator series or for your industrial PPE collection. Skip it if you need a universal, newly manufactured facelet.
