How Effective Is The QT3?

Do you have doubts? That’s normal. We had them too, and that’s why we checked the data.

Lab tests showed that the QT3 filters over 95% of the air right at the outlet. At a distance of 60 cm, the clean air output remains substantial, with air quality being 40% cleaner. Even at 1.2 meters, such as on a desk or bedside table, the air you breathe is still 25-30% purer.

Breathe Clean Air Anywhere, Anytime

Wherever life takes you, fresh air follows suit. The QT3 portable air purifier is going to be your best travel buddy!
