HIGHKA pods feature a dual-channel turbine ventilation system maintaining active airflow throughout occupancy, with air actively refreshed every 30 minutes when unoccupied and a post-use odour clearance cycle after each session. The microwave radar breathing sensor maintains the ventilation system throughout occupancy including during stationary work — preventing the CO₂ accumulation that would otherwise develop during an extended focus session in an enclosed space. All materials are EU E1 formaldehyde-compliant, contributing no additional VOC load to the enclosed air environment.
