Preventing the Spread of COVID-19
To help prevent illness from this virus you should:
- Get vaccinated
- Wear a mask or face covering if inside in areas where social distancing is not possible and immunization status of others is unknown (even if you are vaccinated)
- Social distance when immunization status of others is unknown
- Get tested when exposed or experiencing symptoms
- Wash hands often with soap and warm water or use alcohol-based sanitizer

KN95/N95 Mask Distribution

N95/KN95 Mask Information
N95/KN95 masks are designed for use by adult healthcare professionals. When fitted correctly, N95/KN95s provide protection against COVID-19. But other protective options are also available. We recommend speaking to your healthcare provider to determine which mask is best for you and for each member of your household. Remember: the most effective mask is the one you will wear properly and consistently. Masks should be worn indoors in public spaces, around those whose vaccine status is unknown, and anywhere they are required.
What to Know About Your KN95/N95 Mask
- It is highly effective if worn properly.
- There must be a tight seal between the mask and skin for best protection.
- After repeated uses, it loses it’s shape and may not fit as tightly.
- May cause some difficulty breathing, shortness of breath, fatigue, and dizziness. (Discontinue use if you experience any of these symptoms.)
