✅ Ensures Clean Surgical Environments – Used in operating rooms & ICUs.
✅ Protects Immunocompromised Patients – Critical for bone marrow transplant units & NICUs.

🔹 Key Applications:

  • Hospital HVAC systems (airborne disease control).
  • Negative pressure isolation rooms (e.g., for tuberculosis, COVID-19).
  • Sterile air in operating rooms.

🔹 Filtration Requirements:
✔ HEPA (H13-H14) filters in ventilation systems.
✔ Negative & positive pressure room balancing.

5. Aerospace & Defense Industry
