The present invention is directed to a device consisting of a portable and multi-band UV light device that uses a combination of UVA, UVB, and UVC wavelength band of UV emitters. For detection, UV emitters are energized to a particulate collector that will fluoresce and glow when there is the presence of a wide range of different harmful aerosol droplet particles in the air that may be collected. This instant and positive visual detection with an available audio alarm alert indicates the presence of harmful aerosol droplet particles in the vicinity of this Instant Particulate Detector or IPD device, allowing the user to take immediate and corrective action. The user can also subsequently select disinfection utilizing UVC wavelength light to sterilize the particulate collector and Instant Particulate Detector or IPD device.
