Final answer:
HEPA filters in air-purifying respirators provide effective protection against aerosols.
Step-by-step explanation:
An air-purifying respirator with high-efficiency particulate air (HEPA) cartridges may provide effective protection against aerosols. HEPA filters are designed to remove small particles, including microbes, endospores, and viruses, from the air as it passes through the respirator. By capturing these particles, the respirator can help prevent the inhalation of harmful airborne contaminants.
