Saunum Explained — Why Everyone Is Talking About This New Sauna Technology (2025 Guide)

If you’ve ever sat in a traditional electric sauna and felt burning heat at your face, cold air around your legs, or dry air that makes it hard to breathe, you’re not imagining it — that’s exactly how most electric heaters behave.

And this is why Saunum has exploded in popularity.

Saunum isn’t just another sauna heater.

It’s a full air-mixing system that completely changes how heat, humidity, and airflow move inside a sauna room — creating the soft, balanced, Nordic-style heat people rave about.

In this guide, we’ll break down what makes Saunum so different, why experts call it “the future of electric saunas,” and whether it’s worth the upgrade for your home spa.

What Makes Traditional Sauna Heaters So Uncomfortable?

Before understanding Saunum, it’s important to understand the problem.

1. Uneven Heat Layers (Hot Face, Cold Feet)

In a standard electric sauna, the hottest air sits at the top of the room — often 40–60°F hotter at head level than at your feet.
This creates the classic sauna discomfort:

• Burning sensation near your face

• Cold legs

• Constant shifting around trying to find the “right spot”

2. Dry, Sharp Heat

Because the heat stays trapped near the ceiling, humidity drops to extremely low levels — sometimes under 10%.
This causes:

• Harsh, scratchy heat

• Difficulty breathing

• Very fast drying of skin and sinuses

3. Weak Steam Waves

When you pour water on the stones (löyly), the steam rises instantly to the ceiling and disappears.

So you get a quick flash of heat… and then nothing.

How Saunum Fixes All of This

This is where Saunum becomes revolutionary.

Saunum combines a sauna heater with a patented air-mixing fan system that circulates the hot air, steam, and cooler floor-level air into one smooth, balanced flow.

1. Balanced Heat Everywhere

Instead of heat layers, Saunum blends the air so that:

• Head level and foot level temperatures are nearly equal

• Heat feels deep, enveloping, and comfortable

• You can sit higher or lower and feel the same warmth

No more burning face + freezing toes.

2. Softer, More Humid Heat

By re-circulating the steam instead of letting it escape upward, Saunum increases moisture levels to a comfortable, therapeutic range.

This creates:

• Softer, wetter heat

• Easier breathing

• A true Nordic sauna experience

3. Stronger, Longer-Lasting Steam Waves

When you throw water on the stones:

• The steam doesn’t shoot straight up

• It blends into the air

• You get a deep, rolling steam wave that lasts 3–5× longer

People notice this difference instantly.

Bonus Feature: Himalayan Salt Ionization

This is one of Saunum’s most unique touches.

As the system circulates the air, it passes through a Himalayan salt cartridge that releases beneficial salt ions into the room.

This can help with:

• Air freshness

• Respiratory comfort

• That “clean mountain air” feeling

It’s subtle but noticeable.

Saunum = 3 Problems Solved Automatically

Saunum fixes the things almost EVERY electric sauna gets wrong:

And it does all of this with zero effort.
You just turn the heater on — the air-mixing system handles everything.
