N95 and Surgical Masks Are Now Available As One Unit

Surgical masks and N95 respirators serve distinct purposes in healthcare settings, each designed to offer specific types of protection.

Surgical Masks:

Purpose: Primarily intended to protect patients by preventing the release of large droplets from the wearer, such as saliva or respiratory secretions, into the surgical field. They also provide the wearer with some protection against large droplets or splashes.

Design: Loose-fitting and disposable, creating a physical barrier between the wearer's mouth and nose and potential contaminants in the immediate environment. However, they do not effectively filter smaller airborne particles and do not provide a reliable level of protection from inhaling smaller airborne particles.

N95 Respirators:

Purpose: Designed to achieve a very close facial fit and very efficient filtration of airborne particles, including smaller particles that can be inhaled. They are intended to protect the wearer from airborne hazards.

Design: Tight-fitting with a seal around the nose and mouth, filtering at least 95% of airborne particles. They are approved by the National Institute for Occupational Safety and Health (NIOSH) and, in healthcare settings, may also be cleared by the Food and Drug Administration (FDA) as surgical respirators.

Surgical N95 Respirators:

Purpose: Combine the features of both surgical masks and N95 respirators, providing respiratory protection while also offering the fluid resistance of a surgical mask.

Design: These respirators are both NIOSH-approved as N95 respirators and cleared by the FDA as surgical masks. They are designed to protect against both airborne particles and fluid hazards, making them suitable for use in healthcare settings where both types of protection are needed.

The development of N95 respirators dates back to the 1970s, with the first N95 respirator patented in 1976. A significant advancement occurred in 1980 with the application of electrostatic charge to melt-blown webs, enhancing filtration efficiency. These innovations have led to the modern N95 respirators used today.

In summary, while both surgical masks and N95 respirators are used in healthcare settings, they serve different protective functions. Surgical masks primarily protect the patient and the environment from the wearer’s respiratory emissions, whereas N95 respirators are designed to protect the wearer from inhaling hazardous airborne particles. The combination of these features in surgical N95 respirators provides comprehensive protection in situations where both fluid resistance and respiratory protection are necessary.
