These smaller particulates can cause an array of potential health issues if inhalation or ingestion occurs. Even though this is a downfall for HEPA, the potential for particles smaller than 0.3 microns in environment is unlikely.
  • Mold & Bacteria Growth on Filter. When mold and bacteria accumulate inside the air system on the HEPA filter, these organisms have the potential to grow within the filter. They are microorganisms and when they become collected, they can multiply and become released back into the air.
