QT3 Portable Air Purifier with HEPA Filter

Clean Air Wherever Life Takes You

The QT3 is a compact 3-in-1 portable air purifier and cooling fan designed to give you cleaner air wherever you go. Lightweight and easy to carry, it is ideal for desks, bedside tables, dorm rooms, hotels, commuting, travel, and other personal spaces.

Unlike a conventional fan that simply circulates existing air, the QT3 uses a HEPA filter to help capture airborne pollutants while delivering a comfortable stream of filtered air.

• Personal clean-air zone of up to 1.2 meters

Personal Air Purification in a Compact Design

The QT3 is small enough to fit on a desk, bedside table, or other compact surface, yet powerful enough to provide a personal clean-air zone of up to 1.2 meters.

Its E11 HEPA filter helps capture airborne particles such as:

• PM2.5
• Dust
• Pollen
• Pet hair and dander
• Smoke particles
• Mold particles
• Bacteria and viruses

The result is a more comfortable personal breathing environment at work, while studying, resting, or traveling.

More Than an Air Purifier

The QT3 also works as a personal cooling fan.

Instead of simply blowing unfiltered room air toward you, it draws air through its filtration system before delivering airflow in your direction. You can adjust the fan speed to suit your comfort while enjoying cleaner air.

Designed for Life on the Go

Take the QT3 wherever cleaner personal air matters.

• At Work – Place it beside your computer or workstation for personal air purification.
• At Home – Use it beside your bed, study table, or other personal spaces.
• While Traveling – Bring it to hotels, dormitories, and other unfamiliar indoor environments.
• On the Move – The Travel version includes a built-in rechargeable battery, providing up to approximately 4 hours of operation depending on the fan speed.

Quiet & Energy-Efficient

The QT3 is designed for comfortable everyday use, with three fan speeds and power consumption of approximately 9 W at high speed.

Its low-speed operation is rated at approximately 29 dB, making it suitable for quieter environments such as bedrooms, study areas, and workspaces.
