Replacement F033-GPC Complete 2nd stage Filter for Both Quatro Fume Hoods-Burnout & Rhodium

 

This is the complete metal framed 2nd stage replacement filter for both Quatro fume hoods.  It contains activated charcoal filtering material that can be replaced when no longer effective. Effectiveness is a function of use, so it is impossible to say how often your filter will need to be changed.  This is the odor stage, so when it starts to smell, it's time for a change.

You can purchase the charcoal material separately.  Order Otto Frei part number 147.628D (Quatro part number NC-GPC), for a package that will be enough for 3 refills.
