3M Aura 1870+ N95 Surgical Respirator (Pack of 20)

3M Aura 1870+ N95 Surgical Respirator — NIOSH-Approved N95 Disposable Respirator

3M Aura 1870+ N95 Surgical Respirator uses 3M's three-panel Aura flat-fold construction to create more interior facial volume than a standard cup design — reducing filter media contact with lips during long clinical shifts — while retaining full FDA 510(k) surgical mask clearance and NIOSH N95 particulate approval in a single device.

The 3M Aura 1870+ N95 Surgical Respirator is a NIOSH-approved N95 filtering facepiece respirator from 3M, listed on the NIOSH Certified Equipment List. Read the complete disposable respirator guide to compare NIOSH filter classes before ordering.

Key Features — 1870+

• FDA 510(k)-cleared as a surgical mask AND NIOSH N95-approved — full dual classification
• Three-panel Aura flat-fold design creates more interior volume than cup-shaped surgical N95s
• Fluid-resistant outer layer per ASTM F1862 for blood and body fluid splash resistance
• Flat-fold geometry stores efficiently and unfolds to a larger interior breathing space
• NIOSH approval under 42 CFR 84 for minimum 95% non-oil airborne particle filtration

Hazard Coverage — 3M Aura 1870+ N95 Surgical Respirator

The 3M Aura 1870+ N95 Surgical Respirator is NIOSH-approved under 42 CFR 84 Subpart K for non-oil-based particulates at ≥95% efficiency. Approved hazards include construction and masonry dust, pollen, mold spores, smoke particulates, grain and wood dust, and certain biological aerosols. The 1870+ is NOT rated for oil-based particles — spray paint mist, cutting fluid aerosols, and lubricant mist degrade N-class electret media faster than rated. For oil environments choose an R95 (oil-resistant, one shift) or P100 (oil-proof). Compare classes in our N95 vs P100 guide and the complete disposable respirator guide.

Frequently Asked Questions

Is the 1870+ FDA-cleared as a surgical mask?

Yes. The 1870+ is FDA 510(k)-cleared as a surgical mask in addition to its NIOSH N95 classification — meaning it meets both the fluid-resistance and filtration requirements for surgical environments. This dual clearance is what distinguishes a surgical N95 from a standard industrial N95.

What is the difference between a surgical N95 and a standard N95?

A surgical N95 like the 1870+ carries both NIOSH N95 approval (particulate filtration) AND FDA 510(k) clearance (fluid resistance, biocompatibility for clinical use). Standard industrial N95s are NIOSH-approved but not FDA-cleared. Both provide N95 filtration; only the surgical version is cleared for use in environments where fluid resistance matters.

Is the 1870+ NIOSH-approved?

Yes. The 1870+ is NIOSH-approved under 42 CFR 84 Subpart K as an N95 filtering facepiece respirator. Confirm the TC approval number on the NIOSH Certified Equipment List.

Does the 1870+ require a fit test for healthcare use?

Yes. OSHA 29 CFR 1910.134 and CDC/NIOSH guidelines require fit testing before healthcare workers use N95 respirators for protection against airborne pathogens. See our fit testing guide for protocols specific to cup-shaped and flat-fold surgical N95s.

Can the 1870+ be reused in a healthcare setting?

Standard guidance is single-use or limited reuse per CDC crisis standards of care. In non-crisis conditions, the 1870+ is designed for single-use per manufacturer labeling. CDC contingency and crisis guidance allows limited reuse; consult your facility's infection control policy.

How does the 1870+ compare to KN95 masks?

The 1870+ is NIOSH N95-approved and FDA 510(k)-cleared under U.S. federal standards; KN95 is a Chinese standard that is not interchangeable with NIOSH approval. For regulated healthcare environments, a NIOSH-approved surgical N95 is the appropriate choice, not a KN95.

What size is the 1870+?

See the product title and specifications table for size. 3M offers both standard and small (1860S) sizes in this surgical N95 line. Our respirator sizing guide helps identify the right fit for your face dimensions.

Can non-healthcare workers use the 1870+?

Yes. There is no restriction on industrial workers or general public using a surgical N95 — it provides the same or higher protection than a standard industrial N95 and adds fluid resistance. Browse all surgical N95 respirators.

How many 1870+ respirators come in a box?

See the product title for pack count. Browse all surgical N95 respirators.

What is the shelf life of the 1870+?

3M lists a 5-year shelf life for the 1860 series from production date in original sealed packaging stored in a controlled environment. FDA and NIOSH may extend shelf life under emergency authorization; always check the lot expiration date before use.

Does the 1870+ protect against gases or vapors?

No. The 1870+ is a particulate filter only — it does not capture organic vapors, chemical gases, or other gaseous hazards. It is designed for healthcare aerosol protection and compatible non-oil particle environments.

What fluid resistance rating does the 1870+ carry?

FDA-cleared surgical N95s must meet ASTM F1862 fluid resistance testing. The 3M 1860-series masks are rated for blood and body fluid splash. Check the product's 510(k) summary for the specific ASTM F1862 pressure rating.
