Maintaining a clean evaporator coil optimizes air conditioning system performance. A clean air conditioning coil not only enhances system efficiency but also minimizes maintenance and improves indoor air quality. BLU QR UV Stick Lights offer a simple solution by safeguarding your evaporator coil against biofilm, mold, and odors. Our Series I Indoor Air Quality kit features two BLU QR UV Stick Lights in combination with the HALO Connect power module. HALO Connect provides central power to your IAQ equipment along with a Countdown Day Timer, offering a convenient visual indicator for when it’s time to replace the UV lamp.
