Type B2 Prefilter Replacement 

A Type B2 biosafety cabinet has a prefilter on top of the cabinet, to the left of the 
electronics module.  This prefilter removes large particulate from the room air drawn into 
the biosafety cabinet by the supply blower. When this prefilter becomes loaded with 
particulate, replace it as follows. 
 
 

Note:

 The prefilter is not washable, it must be replaced when dirty. 

 

1. 

Turn off the biosafety cabinet’s blower. 
 

2.  Following all facility safety requirements, use a step ladder to access the prefilter 

atop the biosafety cabinet. 
 

3.  Remove the two thumbnuts that hold the prefilter in place.  See Figure 12-46. 

 

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 

4.  Remove and replace the prefilter.
