Air Filtration Expert Matthew Crouch from Camfil Explains How to Calculate Air Changes Per Hour in a New Video.

As a significant portion of the workforce makes the transition from remote work back to their offices, companies and employees are using air purifiers to protect themselves against the spread of COVID-19. Similarly, school districts are looking to air filtration solutions to protect their students. Air purifiers with true HEPA filtration technology remove infected respiratory droplets from the air as well as supplementing ventilation provided by the building's HVAC system.

However, in order to provide adequate ventilation per CDC recommendations and industry standards, the size or number of air purifiers needed will depend on the volume of the space and airflow of the purifier in question.

In a new video, Camfil air filtration expert Matthew Crouch answers a common query: how do you know how many air purifiers you need and how large?

The video guides viewers through each step of the process:

  • Calculating the volume of air in a room
  • Finding out how many air changes per hour your HVAC system is providing
  • Determining how many air changes per hour desired
  • Identifying the number of air purification units you will need
