Know your air. Breathe better. Stay safe outside.
The FoSen sensor continuously reads PM2.5 fine particles, CO₂ levels, VOC chemicals, temperature, and humidity inside your home — and shows it live on your phone. See your air quality at a glance, any time.
When the sensor detects air quality dropping — from cooking, cleaning products, or outdoor pollution seeping in — the purifier activates automatically. You never have to think about it or press a button.
The Terra Regina app shows live outdoor air quality in your area and sends an alert when pollution rises — so you can adjust your plans, route, or activities before stepping out the door.
