Refillable Carbon Module for SC-150 - DOES NOT INCLUDE CARBON.
This is a permanent module that gets filled with bulk carbon. The carbon can be changed by dumping it out and re-filling. This carbon module is standard on all NEW MicroAir SC-150 models and you DO NOT NEED TO PURCHASE it. If you have on older version of the SC-150 and are ordering the P1992, you will need to purchase this item ONCE. Bulk carbon can be purchased here.
After approximately 6 months of use, the charcoal will need to be replaced. Remove the filter, dump the old carbon and add new carbon.
