TECHNICAL BULLETIN : HEPA Filters for Infection Control – Retrofitting in Various Scenarios
Date: 22nd May 2020

This technical bulletin aims to explain various scenarios and methods of using HEPA filters to introduce infection control in the workplace, hospitals, homes, schools, and other indoor environments.

Improved ventilation and infection control are becoming a requirement in all indoor environments in light of the Corona Virus Pandemic. In some scenarios this will include HEPA filters which can be difficult to retrofit into situations due to their high resistance to airflow, bulky nature and specialist installation requirements.

The following scenarios show how the Airclean HEPA Air Purifier, or Airclean Fan + Filter Indoor Air Quality Filtration System, can be used to quickly retrofit HEPA filtration into your indoor environment, with minimal disruption.
