They may exhaust hepa filtered air back into the lab or may be exhaust outside using a canopy connection.
Biosafety level 1 practices safety equipment and facilities appropriate for work with defined and characterized strains of viable micro organisms not known to cause disease in healthy adult humans.
Biosafety level 1 overview.
Purifier cell logic type a2 and b2 biosafety cabinets have features specialized for cell research.
Special containment practices and devices are generally not required but institutional laboratory practices must be implemented to reduce risk to laboratory personnel.
Biosafety level 1 is specified as work with well characterized agents that are known not to cause disease in healthy non immunocompromised adults.
Purifier logic class ii type a2 and type b2 biological safety cabinets provide personnel product and environmental protection from hazardous particulates and agents that require biosafety level 1 2 or 3 containment.
