While more than 50 percent of the U.S. population are fully vaccinated, COVID-19 positive cases still haven't declined as expected. The Centers for Disease Control and Prevention (CDC) therefore advises all staff, students, and teachers to continue to mask up regardless of vaccination status as plans for booster shots are being put into place.

Masks that are approved by the government for use in indoor settings could offer the highest possible protection by blocking particulates at the micron-level. Furthermore, these masks are widely available as N95 and KN95 masks. They differ slightly in terms of standards and regulations, but are said to offer 95 percent protection against airborne particles.

What Are N95 Masks?

N95 masks are manufactured in alignment with the U.S standards and are approved and regulated by the CDC and the National Institute for Occupational Safety and Health (NIOSH).

These masks comprise several layers of propylene and are said to offer 95 percent protection against airborne particles as small as 0.3 microns. Generally, N95 masks are worn around the face with the help of adjustable straps that form a protective seal around the nose and mouth.
