Disposable Respirators

What is the difference between a cloth face mask and an n95 mask?

A cloth mask is a disposable, loose-fitting barrier to protect against infectious droplets. The material is not desgined to protect against the smallest infectious materials. Medical grade face masks do provide protection agaisnt bacteria and fluid resistance, but don't make claims to protect against viruses like covid-19. The CDC recommends people wear face masks such as Curad masks because N95 respirators are prioritized for health care workers (1).

There are surgical n95 masks that protect against fluids and viruses like covid-19, but you can't get these at your local walgreens or walmart. Harmony sells Gerson surgical n95 masks but prioritizes health care staff. These surgical N95 respirators are class II devices regulated by the FDA, under 21 CFR 878.4040, and CDC NIOSH under 42 CFR Part 84.

N95 and higher rated respirators provide protection against viruses and particles that are smaller than droplets and bacteria. You can read more about the differences between face masks and respirators on the FDA's website (2). The significant difference between surgical masks and respirators lies in their usage and protection levels. No matter the type of personal protective device you use, always ensure that your respirator is always fresh. The respirator should also be able to protect you from any airborne infection.
