EASY CONNECTION Simply download the Saunum app and pair it with your installed, Wi-Fi-connected Saunum AirIQ control unit. IMPORTANT SAFETY INFORMATION Before starting your sauna remotely, always ensure that the heater and its surrounding safety area are free from objects, as specified in the heater's manual. After each session, verify that the heater has switched off and heating has stopped. ABOUT SAUNUM Saunum is redefining the traditional sauna experience with its patented air-blending technology. Saunum's patented air-blending system captures the scorching steam that rises near the sauna ceiling, mixes it with cooler, oxygen-rich air near the floor, and distributes the softer steam evenly throughout the sauna. This creates a more balanced temperature from head to toe and makes breathing more comfortable. The result is softer, longer-lasting steam, more even warmth, and the freedom to enjoy richer steam and more intense sweating without excessive heat around your head.
