Does Yale recommend air purifiers or other local filtration systems? If so, what products are recommended and how will they be purchased and provided?

In areas that are served by centralized HVAC systems providing filtered air and mechanical ventilation, local air filtration devices are not required or recommended to supplement these existing systems currently in place.

In areas that are special use or limited in ventilation capability and are generally less than 500 sf, EHS may require the use of a local air filtration device. In this case, purchase, installation, and maintenance of the device will be provided by the University. All other air purification and filtration devices would be the responsibility of individual departments and users.
