Indoor Air Quality (IAQ) in Hospital

This busy nonprofit hospital needed their air filtration changeout system to be optimized, so that a regular changeout schedule could be established. In order to ensure the well-being of their patients and combat incidents of hospital acquired infections (HAI), this hospital’s Facility Director wanted to make certain that the indoor air quality (IAQ) was the highest quality possible. Providing a comfortable, healthy, and odor-free environment was the highest priority, since patients’ suppressed immune systems make them more susceptible to adverse health effects.

AAF International offered to perform a thorough air filter audit of this hospital’s HVAC systems, in order to provide professional guidance and analysis for cost savings and risk reduction. By conducting this audit, AAF International would be able to optimize the hospital’s filter-related spending.

Challenges 1 – Improves Indoor air quality (IAQ)

Challenges 2 – Regular filter changeout rates

Challenges 3 – High Total Cost of Ownership (TCO)

AAF International worked with the Facilities Director and Manager to perform a complete air filter audit of all HVAC units, pointing out problems/solutions in both critical and non-critical areas where more air flow was needed. AAF International also discussed the prioritization of filter changeouts, systematically examining the air handling units serving each area, including operating rooms, labs, pharmacies, and patient areas. Finally, AAF International developed documentation for a Filtration Quality Control Program.

This hospital’s Facilities personnel now have a complete air filter matrix survey spreadsheet to plan out air filter changes on a timely basis. AAF International’s audit also yielded the following for this hospital:

  • Cost savings
  • Increased air filter performance
  • Targeted filter upgrades
  • More effective planning and scheduling
  • Improved compliance
  • Streamlined operations

The hospital is very happy with AAF International making such a concerted effort to help the Facilities Department implement the hospital’s Filtration Quality Control Program. With AAF International’s assurance that we will help the Facilities staff maintain the best air quality for their patients and employees, only AAF International filters are currently utilized in this hospital.
