Luft Duo Portable Filterless Air Purifier

Breathe the fresh air wherever you are!


What is LUFT Duo?

LUFT Duo is the 3rd generation of LUFT Filterless Air Purifiers. Upgraded from LUFT Cube, the LUFT Duo is still compact but more powerful. It uses UVA LED and Titanium Oxide/Zinc Oxide to zap dust, pollen, mold, and pathogens down to the molecule. The new LUFT Duo is 2x as powerful as the Duo while being even quieter and more efficient. It is capable of handling an expanded range of 240 square feet. You’ll only need one LUFT Duo for your entire house. It’s 1/10th the size of other purifiers in the same category and less than half the price! LUFT Duo removes harmful substances around you and helps you breathe cleaner air anytime, anywhere!

What Makes LUFT Duo Special?

LUFT Duo is the ultimate personal air purifier. You can bring it anywhere or keep it at home to protect those you love from pollutants in the air. Whether you want to get rid of bad odors, defeat your allergies, or improve your indoor air quality, LUFT Duo can do all that for you. LUFT Duo integrates innovative technologies with the minimalist design concept and requires no maintenance, no filter replacements, and no charging batteries.

The Purifying Process: Decompose + Neutralize

The Patented Solid-State Photocatalysis Purification (SPP) Nanotechnology is the core of LUFT Air Purifiers. Pollutants are broken down into harmless molecules by Super Oxygen Substance and Super Free Radicals formed on the photocatalyst’s surface when UVA activates the nano-reactor LED light.

In the below videos, you can see LUFT Duo cleans the smoke in 2 mins. Fresh fruits stored near LUFT Duo remains mold-free after 2 days in room temperature.

What has been improved on Duo?

  • More innovative photocatalyst material techThe newly added ZnO-Ag(Zinc Oxide) Photocatalyst module combined with the original TiO2(Titanium Oxide) Photocatalyst boosts the bacteria-killing performance by 34% and the formaldehyde neutralization performance by 103%.
  • Enhanced photocatalyst structureCompared to the LUFT Duo, which has a flat photocatalyst structure, the LUFT Duo comes with a new patented 3D photocatalyst structure. The 3D design increases efficiency by 62%.
  • Electro-static dust collection: The negative ion generator placed at the bottom LUFT Duo makes the PM2.5/PM10 matter actively trapped by the metal mesh. This novel approach prevents droplet infection effectively.


How does LUFT compare to HEPA?

HEPA only traps pollutants


LUFT destroys harmful pollutants ACTIVELY! LUFT is the ONLY technology that destroys formaldehyde & toxic VOCs, which are too small for HEPA.
