This page describes products and general use; it is not medical advice.
Anyone placing a first case-quantity order for N95 respirators, such as a clinic manager, facilities buyer or small-business owner, can use this page as a verification checklist. It covers what to check on the approval, which records apply, and which label elements to look for on inner and outer packaging before the order is placed. It lists no prices and ranks no suppliers.
What should I verify before placing a first order?
Verify that the exact model is NIOSH-approved, and that the packaging carries the markings federal regulation requires. NIOSH guidance says the easiest confirmation is to search the NIOSH Certified Equipment List (CEL) using the approval number, which has the format TC-84A-XXXX. A respirator missing any required label component is not a NIOSH-approved respirator, according to the same NIOSH page (checked 2026-11-01).
- Get the approval (TC) number and model number from the seller before ordering, then look both up on the CEL yourself. See how to search the NIOSH approved respirator list.
- Confirm the filter designation. Under 42 CFR 84.170, N95 means a minimum filter efficiency of 95 percent; N-series filters are restricted to workplaces free of oil aerosols, while R and P series filters cover oil-based particulates.
- Confirm the listing matches the product class you intend to buy. The guides on what an N95 respirator is, N95 sizes and N95 versus N100 explain those classes.
What documents should I ask the seller for?
Ask for records that tie the product to its approval, so you can check them yourself instead of relying on a listing title. The list below follows what the regulation and NIOSH say a legitimate product carries.
- The NIOSH approval number (TC prefix plus serial number) for the exact model, in writing, so you can search the CEL.
- The approval holder’s name and address, which the label must show under 42 CFR 84.33(b). The holder and the seller are not necessarily the same company; approval labels may only be used by the applicant to whom they were issued (84.33(d)).
- A photograph or sample of the full label and of the respirator marking, so you can compare them with the elements in the table below before committing to a case quantity.
- For a product described as a surgical N95, the FDA record for the device as well (see the section on surgical N95s below).
What the label must show
The table is drawn from 42 CFR 84.33 and the NIOSH page “Identifying NIOSH Approved Respirators” (both checked 2026-11-01).
| Element | What the source says | Source |
|---|---|---|
| NIOSH emblem and HHS seal | Approval labels bear the NIOSH emblem and the seal of the Department of Health and Human Services. | 42 CFR 84.33(b) |
| Applicant name and address | Shown on the approval label. | 42 CFR 84.33(b) |
| Approval number | Assigned by NIOSH, prefix TC followed by a serial number. | 42 CFR 84.33(b) |
| Trade name or number, plus lot number, serial number or approximate date of manufacture | Each respirator or container is labeled to show the applicant’s name, the trade name or number, and the lot number, serial number or approximate date of manufacture, as NIOSH requires. | 42 CFR 84.33(g) |
| Where the full label appears | For particulate respirators, the entire label goes on the respirator container and the filter container; filters carry an abbreviated label. | 42 CFR 84.33(e) |
| Elements on a filtering facepiece | Approval holder name or logo, “NIOSH” in block letters, TC number, model number and filter designation such as N95. | CDC/NIOSH |
Because the full label is required on the container, an outer case alone does not tell you everything: check the inner box and the respirator itself against the table.
N95 versus surgical N95: which record applies?
A surgical N95 is a subset of N95 filtering facepiece respirators. NIOSH regulates N95s under 42 CFR Part 84, and FDA regulates surgical N95s as Class II devices under 21 CFR 878.4040 (FDA page current as of 10/21/2024, checked 2026-11-01). Some N95s are exempt from 510(k) review, but the FDA page notes the exemption does not apply in cases such as a claim to filter specific viruses or bacteria. If a listing calls the product a surgical N95, ask for the NIOSH approval and the FDA record. FDA says all FDA-cleared N95 respirators are labeled single-use or disposable. Compare the related surgical mask and face mask types guides.
What lot and date information should be on the label?
Regulation requires the lot number, serial number or approximate date of manufacture on the respirator or its container (42 CFR 84.33(g)); the NIOSH identification page describes lot number and manufacture date as recommended but not required label elements. Ask which of these the product carries, and keep it with your receiving records so a lot can be traced to the manufacturer later. For any dated shelf-life or expiration marking, ask the seller to state it in writing for the lot you are buying, and see PPE stockpile and surge demand planning.

Common mistakes
- Treating a product title that says “N95” as proof of approval. The approval is tied to the TC number and model, which you check on the CEL.
- Checking only the outer case. The entire label belongs on the respirator container and filter container (84.33(e)).
- Assuming the seller is the approval holder. The label names the applicant, and only that applicant may use the approval label.
FAQ
What should I verify before placing a first order?
Check the TC approval number and model on the NIOSH Certified Equipment List, and confirm the label shows the elements in the table above. A missing required label component means the respirator is not NIOSH approved.
What documents should I ask the seller for?
The TC number and model in writing, the approval holder’s name and address, a picture of the full label and, for a surgical N95, the FDA record as well.
What lot information should be on the label?
Federal regulation calls for a lot number, serial number or approximate date of manufacture; ask the seller to state any shelf-life or expiration date for the lot in writing.
