It's an extension of the tech that L'Oréal introduced at CES 2024 with the Airlight Pro hairdryer. In a nutshell, most conventional hair styling tools rely on heated coils and motors. The Airlight Pro hairdryer introduced infrared light to help speed up drying while reducing the overall heat required. (I've been doing some long-term testing of the high-tech hair dryer versus a standard one over the past year, and I can confirm that it is much faster.)
Home heating is notoriously hard to get right. Most of us have that one room that's never quite warm enough, so we reach for a plastic, fan-blasting space heater that's loud, dries the air, kicks up dust, and looks out of place. Central systems often overheat empty rooms and underheat the ones we're in, wasting energy along the way. What's missing is a safe, efficient, affordable way to warm the spaces that need it, right when they need it.
