IAQM has been decontaminating exotoxins since 2002. No other company has as much success as IAQM, with millions of cubic air space successfully decontaminated.

An exotoxin is a toxin secreted by bacteria. An exotoxin can cause damage to the host by destroying cells or disrupting normal cellular metabolism. They are highly potent and can cause major damage to the host. Exotoxins may be secreted or, similar to endotoxins, released during lysis of the cell. Gram-negative pathogens may secrete outer membrane vesicles containing lipopolysaccharide endotoxin and some virulence proteins in the bounding membrane. These vesicles may also contain other toxins as intra-vesicular contents, thus adding a previously unforeseen dimension to the well-known eukaryote process of membrane vesicle trafficking, which is quite active at the host-pathogen interface.

Exotoxins are susceptible to antibodies produced by the immune system, but many exotoxins are so toxic that they may be fatal to the host before the immune system has a chance to mount defenses against them. For this reason, antitoxin – anti-serum containing antibodies – is injected to provide passive immunity.
