Abstract: An air quality and particulate detection system comprising: an air quality and particulate detector comprising a particulate detection chamber in fluid communication via an orifice with an adjacent air quality member, the particulate detection chamber comprising a blower adjacent to a particle filter and a laser source, and the air quality member comprising a channel having substantially parallel sides for operably coupling a HEPA filter adjacent and substantially parallel to the orifice, and for operably coupling one or more ultraviolet light emitting diodes (LEDs) downstream from the HEPA filter, and an exhaust pipe for returning treated air to a protected area; one or more pipe runs fluidly connected to the particulate detection chamber, wherein each of the one or more pipe runs includes one or more sampling points configured to allow air particulate entry from the protected area, into at least one of the one or more pipe runs.
