Yes dvdegeorge ,
but it is also filtering liquid and gaseous wastes too . How do you know your suits weren' t working , did you get busted ? I' ll agree with most that carbon isn' t bulletproof , but It does seem to help with odor reduction . I haven' t tried AbScent or Contain products personally , but the tech behind them seems sound . Bacteria cause most of the odors we emit from the skin , and anything that suppresses bacteria must work at some level .
