The full FreshBed technology is housed in a full metal insulated unit – and the Active Climatized Airflow System is well hidden inside the bed’s base at the foot end away from the body. The silent fan operates on a 24 Volt low-voltage current, making it extremely safe to use and the enclosure of the unit has a Cage of Faraday construction for preventively blocking possible electromagnetic fields. The Active Climatized Airflow System is compliant with US Federal regulations and approved against UL 499 and FCC Part 15.107 & 109. During sleep, WIFI can be switched off to eliminate the EMF radiation. Features like: Promote Falling Asleep, Waking up and Bed Hygiene Boost can still be used while the WIFI is switched off. Instead of using WIFI the FreshBed can also be controlled with a Remote Cable Control without an internet connection. Disclaimer: The FreshBed consumption can be cost neutral since you power usage of the heating system and AC unit can be reduced during sleep as well as humidity control in the FreshBed reducing the number of times bed linens may need to be washed.  Environmental factors and personal preferences can impact the energy consumption of the heating systems and AC unit.
