Lux Electrostatic (powered by InCharged) is an electrostatic spray cleaning mechanism that electrically charges the chemical solution so that when released the solution quickly bonds to surfaces instead of falling straight to the floor. This technology, typically used to sterilize offices, restaurants, universities and public transportation, is now available commercially for faster sanitizing times thanks to LuxElectroStatic. Nozzle options: There are two: 15 micron (metal nozzle) and 40 micron (plastic) - metal is recommended for disinfecting.
