Air Series, 5kW Sauna Heater Package

Experience a new standard in sauna comfort with perfectly balanced heat, breathable air, and a fully customizable wellness experience.

Unlike traditional sauna heaters that create intense heat near the ceiling and cool air at your feet, Saunum's patented Air Blending System transforms the way you experience every session. By continuously drawing hot air and steam from the ceiling, blending it with cooler, oxygen-rich air near the floor, and redistributing it evenly throughout the sauna, Saunum creates a more comfortable and consistent environment from head to toe.

The result is a room with over 60% greater temperature consistency, allowing you to enjoy longer, deeper, and more relaxing sauna sessions with improved comfort and more intense sweating.

Breathe Easier with Balanced Air

Traditional saunas often leave your head overheated while your feet remain cool. Saunum eliminates this imbalance by equalizing both temperature and oxygen levels throughout the room, creating softer, more breathable air for a noticeably better sauna experience.

Himalayan Salt Therapy

A patented Himalayan salt chamber releases natural salt ions into the circulating air, filling your sauna with beneficial salt aerosols. Long valued for their ability to support respiratory health, reduce inflammation, and provide natural antimicrobial benefits, these ions add another level of wellness to every session.

Elevate Your Experience with Aromatherapy

Enhance relaxation by adding your favorite sauna aromas. Saunum's advanced airflow and humidity create the ideal environment for aromatherapy, allowing essential oil scents to circulate evenly throughout the room for a truly immersive experience.

Six Sauna Experiences in One Heater

Customize every session by adjusting airflow, humidity, and temperature to match your mood and wellness goals.
