## Filtration & Fit

### N95 filtration, at least 95%

NIOSH approved under TC-84A-5726. The 3M proprietary filter media captures at least 95% of airborne particles, with greater than 99% bacterial filtration efficiency (BFE).

**Filters at least 95% of:**
- Airborne particles
- Bacteria-size particles
- Biological aerosols
- Fine particulates

### Keeps eyewear clear

An embossed top panel directs warm, exhaled breath away from the eyes to help reduce fogging of glasses, goggles, and face shields.

### Sculpted nose, close seal

A sculpted nose panel follows the contours of the face, while an adjustable aluminum nose clip with soft foam shapes to a secure, comfortable seal.

### Built for the operating room

As a fluid-resistant surgical mask, the 1870+ helps protect against splash and spatter of blood and other fluids, meeting the highest ASTM F1862 fluid-resistance level at 160 mmHg. Approved by NIOSH and cleared by the FDA for surgical, patient-care, and TB-exposure settings.

### Comfort for full-shift wear

- **Stapled head straps** - Two braided polyisoprene straps go over the head and behind the neck to keep pressure off the ears. Latex-free.
- **Innovative chin tab** - A built-in chin tab makes the respirator easy to position, don, and adjust in a single motion.
