Do N95 masks protect against mold?

Yes, N95 masks can provide some level of protection against mold spores. The "95" in N95 refers to the mask's ability to filter out at least 95% of airborne particles, including mold spores, which typically range in size from 1 to 100 microns. This makes N95 respirators effective at reducing inhalation of mold spores, which can cause allergic reactions, respiratory issues, and other health concerns, particularly for individuals with sensitivities or weakened immune systems.

However, it's important to note that N95 masks are primarily designed to filter particles and may not offer adequate protection against mold-related mycotoxins (toxic chemicals produced by mold) or other gases associated with mold growth. If you're working in an environment with significant mold contamination, or if you need protection against specific mold-related hazards, it's a good idea to use a respirator with appropriate filters or cartridges designed for those risks. Always ensure a proper fit to maximize the effectiveness of the mask.
