How does AS150MM differ from a HEPA filter?
HEPA filtration devices capture particles (down to 0.3 micron in size), and the filters need to be replaced. AS150MM is a cold incineration device which actually destroys the airborne contaminants. Different contaminants are neutralised and destroyed in different manners, depending on their chemical properties. AS150MM is not a filtration device, and no parts need to be replaced or serviced.
