The cleanest air,
where your child sleeps.

Indoor air can be 2 to 5 times more polluted than outdoor air. In winter, with home heating, it is often worse. Terra Regina measures the air in your home and acts on its own when needed.

Watch

Clean air
at home.

A sensor, a purifier and an app: how it works in a family home, in 80 seconds.

Who it is for

For those who
breathe most sensitively.

Everyone breathes better in clean air, but for some it matters most.

👶

Children and babies

They breathe faster than adults and their lungs are still developing. They spend half the day in their room, most of it asleep.

👵

Older people

Fine particles strain the heart and breathing. Clean air at home means less effort for those with high blood pressure, asthma or COPD.

🤧

Allergies and asthma

Dust, pollen and stove smoke. The purifier catches them before they reach you, and the sensor shows when it happens.

What you get

Three parts,
one system.

Start with the sensor only. Add the purifier and tablet whenever you like.

Complete kitSensor, purifier and tablet for the whole family
A day in your home

It runs itself,
morning to morning.

Nothing to switch on. The system watches and responds.

  1. Morning

    The air is clean. The tablet shows green.

  2. Cooking

    PM2.5 rises. The purifier switches on by itself and within 20 minutes the air is clean again.

  3. The child's room

    Door closed, CO₂ rising. An alert arrives on your phone: air the room for 5 minutes.

  4. Night

    Your child sleeps in clean air. The purifier runs quietly, only when needed.

And outside

Know the air
outside your door too.
