No. HIGHKA pods feature a dual-channel turbine ventilation system that maintains active airflow throughout occupancy. The microwave radar breathing sensor ensures the system detects presence via respiration and maintains ventilation even during stationary work — unlike PIR-based systems that can time out during still, focused sessions. When unoccupied, the system actively refreshes the air every 30 minutes. After each use, a post-use odour clearance cycle prepares the pod for the next user.
