Overhead, out of sight, the patented UV24 system provides continuous ultraviolet protection against airborne pathogens, all safely hidden behind standard-sized fluorescent or LED ceiling lights. The fast, continuous UV24 air purification system works around the clock to provide fresh, clean air to breathe. UV24 combines an ultraviolet germicidal irradiation (UVGI) chamber and air circulating fans with an overhead ceiling light to allow for 24/7 operation in occupied spaces. UV24 can treat a volume of air equivalent to a 10 x 10 x 8 room, four times per hour.
