Saunum Air 5 Sauna Heater Package 5kW with Wi-Fi

Most saunas suffer from extreme temperature variance from floor to ceiling — the ceiling can exceed 200°F while the floor stays under 100°F, leaving your head overheated and your feet cold. Saunum's patented heat equalizing module solves this entirely. It draws hot, oxygen-poor air from near the ceiling, mixes it with cooler, oxygen-rich air near the floor, and redistributes blended, breathable air evenly throughout the room — resulting in a more comfortable, longer, and more intensely sweating session at any temperature preference.

Seven Himalayan salt spheres are positioned within the air stream so that salt ions are propelled throughout the sauna during every session. The AirIQ Wi-Fi control allows full remote management from the Saunum mobile app — set temperature, session duration, and sauna style, then schedule sessions for a specific day and time so your sauna is ready when you arrive.

Six sauna styles

• Russian Banya — air blending, massive stone volume, intense heat, and steam
• Finnish Sauna — intense, dry heat with huge rock mass for consistent radiant heat
• Estonian Sauna — long sweats, soothing heat, and rich steam
• Yoga Sauna — oxygenated, equalized airflow for hot yoga at floor level
• Salt Sauna — patented system propels Himalayan salt ions throughout the room
