The HUUM Mini Air Tunnel is an internal performance accessory made specifically for HUUM HIVE Mini electric sauna heaters in 6.0, 9.0 and 10.5 kW. Installed in the center of the stone cage, this high-grade stainless steel insert creates a chimney effect that draws fresh air up through the stones, helping the sauna heat up faster and hold a more even, consistent warmth throughout the room.
By improving airflow, the Mini Air Tunnel speeds heat-up by up to 25% and reduces the required stone load by roughly 66 lb, about two boxes, making loading and maintenance easier. It also eases thermal stress on the heating elements for steadier, longer-lasting operation, without changing the rich, stone-driven character of HUUM's signature löyly. Designed and made in Estonia, it is a simple internal upgrade for faster, more responsive HIVE Mini sauna sessions.
