✓ For: HUUM Hive and HUUM Hive Mini — pre-2025 models only (2025 models include this as standard)
All 2025 HUUM Hive and Hive Mini models include the air tunnel as standard. If you have a pre-2025 model, this listing is the retrofit option. The air tunnel channels airflow through the heater core, cutting heat-up time by approximately 25% and shielding heating elements from direct water contact — the main cause of premature element failure.
Not sure if your model needs it? Call 866-861-6317 with your heater model and production date.
Why Buy From RecovAthlete
We're an authorized HUUM dealer. We confirm whether your Hive or Hive Mini needs the retrofit based on production date.
Call 866-861-6317 before ordering.
"The HUUM Air Tunnel cuts heat-up time by 25% and roughly doubles heating element lifespan — standard on 2025 models, available as a retrofit for earlier Hive and Hive Mini owners."
