Product Overview

A More Balanced Way to Experience Traditional Sauna

The Saunum Air 5 Sauna Heater with Climate Equalizer is not a typical electric sauna heater. It combines traditional sauna heat with Saunum’s patented air blending technology to create a more even, comfortable sauna climate from head to toe.

In many traditional sauna rooms, the hottest air collects near the ceiling while cooler air remains closer to the floor. This can create intense heat around the head and shoulders while the legs and feet stay noticeably cooler. Saunum’s climate equalizing system was designed to help reduce that temperature layering by drawing hotter air from the upper sauna room, blending it with cooler air from the lower room, and circulating the mixed air back into the sauna.

The result is a softer, more balanced heat experience while still preserving the ritual of authentic sauna bathing: hot stones, water-pouring löyly, deep warmth, and a calm, immersive atmosphere.

The Air 5 is ideal for compact to mid-size traditional sauna rooms and is especially compelling for customers who want the feeling of a true sauna with more full-body comfort than a standard electric heater can provide.

Key Features

More Even Heat from Head to Toe

Saunum’s patented air mixing system helps blend hotter air near the ceiling with cooler air near the floor, creating a more balanced sauna climate throughout the room.

Traditional Sauna Heat + Modern Climate Control

Use the Air 5 as a traditional electric sauna heater, or activate the climate equalizer when you want softer, more even heat.

Designed for Authentic Löyly

The Air 5 is built for traditional sauna bathing, allowing you to pour water over heated sauna stones to create steam and humidity.

Large Stone Capacity

With approximately 110 lbs of stone capacity when used with the protective grille, the Air 5 provides a generous stone mass for steady heat and beautiful steam.

Includes Himalayan Salt Spheres

The Air 5 includes Himalayan salt spheres designed for placement in the outgoing air path when the climate equalizer is active.

Premium AirIQ Control Compatibility

When paired with the required Saunum AirIQ controller, the Air 5 gives you digital control over temperature, air circulation, humidity settings, and optional WiFi app control.

Ideal for Compact to Mid-Size Sauna Rooms

The Saunum Air 5 is designed for sauna rooms approximately 106–212 adjusted cubic feet, making it a strong choice for many residential indoor and outdoor traditional sauna builds.

Available in Black or Stainless

Choose a finish that complements your sauna interior, from modern black contrast to clean stainless steel.

What Makes Saunum Different?

Climate Equalization, Not Just Heat

Most electric sauna heaters create heat and rely on natural convection to move that heat through the room. Saunum goes further by integrating a climate equalizing system directly into the heater design.

The Air 5’s fan system draws hot air from the upper sauna room and cooler air from the lower sauna room, blends the two, and circulates the more balanced air back into the cabin. This helps reduce the sharp temperature difference between upper and lower bench levels and creates a more consistent sauna environment.

For customers who find standard sauna heat too intense around the head, or who want warmer feet and a more even full-body sweat, Saunum offers a unique and highly differentiated sauna experience.

Is the Saunum Air 5 Right for Your Sauna?

Best for Compact to Mid-Size Traditional Sauna Rooms

The Saunum Air 5 is best suited for sauna rooms approximately 106–212 adjusted cubic feet.

To calculate your basic sauna room size:

Length × Width × Height = Cubic Feet

Then account for cold surfaces such as:

Glass walls or large glass doors
Tile
Stone
Brick
Concrete
Log walls
Other uninsulated or heat-absorbing surfaces

These surfaces increase the effective heating demand of the sauna room. If your sauna has significant glass, tile, stone, or other cold surfaces, you may need a larger heater model.
