Tube: The smart air purifier that breathes clean air
Powerful and connected
Elegance and performance come together in Tube, the smart air purifier with a stunning capacity of 550m3 per hour CADR (Clean Air Deli very Rate). Tube is suitable for spaces up to 75m2 and ensures optimal removal efficiency thanks to its triple-layer protection, including Pre, HEPA H13 and Activated Carbon filter. Tube effortlessly cleans the air in an entire room in just 20 minutes and automatically adjusts the wind speed according to the air quality measured by the PM2.5 laser sensor. And with the new Duux app, Tube can be operated anytime, anywhere.

Powerful and connected

Appearance matters. That’s why Tube is not only extremely powerful, but also an eye-catcher in any room. Its capacity of 550 m³ per hour Clean Air Delivery Rate enables it to clean the air in a room of up to 100 m² in just 20 minutes. The Duux app ensures easy operation – or simply use the buttons.

Designed for elegance

Tube is more than just a smart air purifier. Its elegant design – characterized by a matt finish, organic round shape and the clever leatherette detail on the air outlet – make Tube the perfect addition to any room. And no need to worry about noise: its powerful brushless DC motor is as quiet as can be.

Built to perform

Clean air is vital for your health. Good thing that Tube is so powerful it removes 99.97% of all airborne particles and pollutants in a room. Moreover, you can accelerate its efficiency by activating the built-in ionizer that spreads negative ions to capture even the smallest dust particles.

Looking after your health

Thanks to its PM2.5 sensor, Tube turns on automatically when the air quality is poor. It has 3 speeds and a 1 to 8-hour timer mode, shutting down automatically according to your wishes. Its ionizer can be operated separately, and the filter lifespan indicator alerts you when the filter needs replacing.

Convenient controls

You decide how you want to operate Tube: using the DUUX app with its visual interface, or the integrated buttons on the top ring. The high-resolution LCD screen shows all values of the air, including particle matter (PM2.5), temperature and humidity. So you’re always on top of your indoor air quality.

Multiple air changes per hour

CADR (Clean Air Delivery Rate) indicates how many cubic metres the air cleaner can clean in one hour. However, in certain situations it is desirable to clean the air several times an hour. For basic cleaning, 2 air changes per hour are sufficient, while asthmatic patients only notice a difference at 5 air changes per hour. The calculation of the recommended space is based on a standard ceiling height of 2.5 metres. Below are the recommended number of square metres per the amount of air changes per hour:

2 air changes per hour (basic cleaning) = 550/2,5/2= 110m²

3 air changes per hour (allergies) = 550/2.5/3 = 75 m²

5 air changes per hour (asthma/medical) = 550/2.5/5 = 45m²

Meets the highest quality standards
At Duux, we value quality and integrity, which is why our products are independently tested. Tube is officially certified by the leading German research institute IUTA at a Clean Air Delivery Rate (CADR) of at least 550m³/hr. This is tested through measurements that compare the reduction in particle concentration with and without the air purifier.
