1. An apparatus comprising:
an air filter configured to filter particulates from air passing in a fluidic path through the filter;
a detachable sensor frame including attachment points for removably mounting the sensor frame on the air filter, ahead in the fluidic path of the air filter:
a sensor mesh that is supported by the detachable sensor frame and that includes multiple biological sensor elements that are (i) sensitized to fluoresce when in contact with a particular pathogen, and (ii) distributed across the detachable sensor frame to cover a face of the air filter that comes after the detachable sensor frame in the fluidic path;
an optical sensor that is affixed to the detachable sensor frame that is configured to detect, and to output a signal indicating, fluorescence from any of the biological sensor elements that are distributed on the detachable sensor frame; and
a control unit that is affixed to the detachable sensor frame and that is in data communication with the optical sensor, the control unit being operable to perform operations comprising:
receiving, from the optical sensor, an indication that fluorescence was detected from one or more of the biological sensor elements that are distributed on the detachable sensor frame;
in response to receiving the indication, generating, by the control unit, a pathogen alert response; and
providing, by the control unit, the pathogen alert response.
