Abstract
Embodiments described herein relate to a method for utilizing a roomside replaceable fan filter unit having an integral aerosol injector ring. The method begins by replacing a used filter from the fan filter unit with a replacement filter from a roomside of the fan filter unit. Air is then pulled into a housing of the replaceable fan filter unit and out through the replacement filter to the roomside by a fan module. Finally, an aerosol challenge is provided at a location adjacent and upstream of the fan module.
