·      PX-UV lamps do not contain mercury, unlike their ultraviolet-C irradiation bulb 
       counterparts (Nerandzic et al., 2015). 

·      Minimal disruption to patient flow (Hosein et al., 2016)

·      Well received by hospital cleaning and unit staff (Hosein et al., 2016)

·      Short, 10-minute exposure time (Nerandzic et al., 2015)

·      Several safety mechanisms to prevent accidental UV exposure

·      Each Xenex costs about $80,000, and they can 
       be bought or leased. An average-sized hospital 
       with 120 beds would require two devices to 
clean all its rooms (Zimmerman, 2012).
