QT3 Portable Air Purifier

Clean Air Wherever You Go

Meet the QT3: the compact, powerful personal air purifier designed to keep your breathing space clean and safe—whether you’re commuting, in a cafe, or at your desk. Its minimal design and solid performance make it the perfect complement to your daily life.

Creates a Clean Air Bubble Around You

Purifies your personal breathing zone

The QT3 delivers a Clean Air Delivery Rate (CADR) of 37 m³/h, powerful enough to create a protective clean-air bubble reaching up to 1.2 meters from the purifier—perfect for desks, bedside tables, or on-the-go use.

Usable Distance: Up to 1.2 m

CADR m3/hr: 37

Speed: 1-2-3 (button control)

Compact & Truly Portable

The QT3 weighs only 0.72 kg and is about the size of a small speaker. Its lightweight body and clean design make it easy to carry in a backpack, place on your office desk, or even use in a car. Whether you’re traveling, working, or studying, it brings clean air wherever you go.

Powerful HEPA Protection

Equipped with an H11 medical-grade HEPA filter, the QT3 removes over 95% of airborne particles—including dust, pollen, bacteria, and viruses—on a single pass. Unlike ionizers or ozone generators, it uses safe mechanical filtration with no harmful byproducts, making it suitable for daily and long-term use.

Built-In Rechargeable Battery

The QT3 comes with a 2,000 mAh lithium-ion battery, giving you clean air wherever you need it. Enjoy up to 4 hours of runtime on a single charge (low speed), with around 3 hours on medium and 2 hours on high. Fully recharges in about 3 hours via USB, making it travel-friendly and hassle-free.

Creates a Personal Clean Air Zone

Instead of trying to clean an entire room, the QT3 focuses on what matters most—your immediate breathing space. With an airflow reach of up to 1.2 m, it delivers a protective “bubble” of clean air around your nose and mouth, significantly reducing exposure to pollutants in crowded or poorly ventilated spaces.

Energy Efficient

Consuming only 9 W at maximum power, the QT3 is designed to deliver strong performance without draining your power bank or wasting energy.
