Engineered for homes, offices and boardrooms, schools, professional studios, hospitals and medical clinics, the Ariosa DOT is a controlled mechanical ventilation system that delivers constant, balanced air exchange for a comfortable, hygienic indoor environment.
Think of it as a virtually silent set of powerful lungs, built to filter large spaces. It pulls in fresh air from outside and pushes it through an EPM1 filtration system that blocks pollen, smog and other pollutants, while expelling stale air loaded with excess moisture, mould spores, NO2 from gas fuels, cooking odours, formaldehyde, dust mites, pet dander and toxic radon gas — and significantly reduces airborne viruses and bacteria along the way. The compact unit cuts humidity and condensation, keeping conditions inhospitable for mould, while recovering 90% of the heat from outgoing air to save energy. All controlled via a WiFi-enabled app.

“Since installing the Ariosa DOT into our home, the difference in air quality has been noticeable. The room feels fresher throughout the day, and we've had far less condensation on the windows in the mornings. It is incredibly quiet, so you forget it's even running.”

“We love that we don't need to open the windows for fresh air. The filtered airflow helps keep pollen and dust out, which has a real benefit for our children who suffer from allergies.”

“We installed Ariosa DOT in several rental properties where condensation had become an ongoing issue. The installation was straightforward, and our tenants have commented on how much fresher the rooms feel. It's been an excellent addition to our maintenance strategy.”
