Face masks have become a crucial part of our daily lives, especially as many states are now mandating their use in public spaces. It’s important to understand the different types of face masks, their levels of protection, and when each type should be used. This guide will walk you through the essentials to help you stay safe in our "new normal."
Types of Face Masks and Their Uses
There is a wide variety of face masks available, each designed for specific levels of protection and duration of use. Some masks only prevent bacteria from being shed in droplets from the wearer’s mouth and nose, while others protect against dangerous airborne pollutants and gases.
In situations where the risk of illness from airborne contaminants is high, wearing the appropriate face mask can safeguard your respiratory system. Below, we explain the most common types of face masks:
N95 and N100 Respirator Masks
The 'N' in N95 and N100 masks stands for "Not Oil Resistant". These masks are ideal for filtering particles but not oil-based contaminants. The number indicates the percentage of airborne particles the mask filters:
- N95: Filters at least 95% of airborne particles.
- N100: Filters at least 99.97% of airborne particles.
N95 and N100 respirators are classified as Air-Purifying Escape Respirators (APER). They are commonly used by the general public for protection during chemical, biological, radiological, and nuclear incidents. These masks are also effective in protecting against viruses, such as COVID-19, and bacteria transmitted through airborne particles.
While N95 masks are disposable and inexpensive, they must be replaced after one-time use. Always ensure the mask covers both your nose and mouth for optimal protection.
Homemade Masks: A Last Resort
In settings where commercial masks are unavailable, homemade masks—like bandanas or scarves—can serve as temporary alternatives. However, they are not classified as PPE (Personal Protective Equipment) because their effectiveness is uncertain.
When using homemade masks, it’s best to combine them with a face shield that covers the entire front of your face, extending below the chin and along the sides.

CDC Recommendations
“If used correctly, face masks and respirators may help reduce the risk of getting influenza, but they should be used along with other preventive measures, such as avoiding close contact and maintaining good hand hygiene.”
Key Takeaways
- Use N95 or N100 respirators for high-risk situations requiring significant protection.
- Ensure your mask covers both your nose and mouth to prevent the spread of illness.
- As a last resort, opt for homemade masks, ideally paired with a face shield for added protection.
Final Thoughts
Face masks play a crucial role in preventing the spread of airborne illnesses like COVID-19. Choosing the right mask depends on the level of protection you need. Whether you’re using N95 respirators or DIY face coverings, remember to follow safety guidelines and practice good hygiene.
