MASKS & AIRBORNE AWARENESS

Airborne diseases are among the easiest illnesses to catch—and the easiest to reduce with the right precautions. When it comes to masks, the only options that provide serious, reliable protection against airborne particles are N95 and KN95 respirators. These masks are engineered to filter at least 95% of the smallest particles that spread infection, including viruses, wildfire smoke, air pollution, and fine aerosols that easily pass through cloth or standard surgical masks. While public messaging has often blurred these distinctions, the evidence is clear: loose-fitting masks offer limited protection, while a properly fitted N95 or KN95 dramatically lowers exposure, especially in crowded indoor spaces, during travel, or in poorly ventilated environments. Wearing a high-quality respirator is not about fear—it is about using a tool designed for airborne risk, particularly during surges of COVID-19, influenza, RSV, or during periods of unhealthy air quality. In a world where airborne threats shift quickly, paying attention to the air you breathe and choosing proven protection is a practical form of personal resilience.

Mask tips:

- Use N95 or KN95 masks—these are the only masks designed to provide high-level protection from airborne particles

- Make sure the mask fits snugly, with no gaps around the nose, cheeks, or chin

- Wear a respirator in crowded indoor spaces, on public transportation, or while traveling

- Avoid touching the inside of the mask

- Replace masks if they become wet, damaged, visibly dirty, or no longer seal well

- Keep a spare N95 or KN95 in your bag or car for unexpected exposures

Masks remain one of the simplest and most effective tools during surges of flu, COVID-19, RSV, wildfire smoke, or pollution—especially when higher-grade respirators like N95s and KN95s are used correctly.
