LUFT Duo has been invented and designed as smallest and filterless air purifier that combines two technologies: "Electro-static dust collection" and "Photo-catalysis" to clean the air we breathe.

2) Electro-static dust collection: Producing 20 million ions at all times allow PM2.5/PM10 to be actively trapped in the metal mesh. This novel approach works effectively for droplet infection in epidemic routine. 

3) Photocatalyst to decompose: We developed revolutionary photocatalysis nanotechnology to break down and destroy VOCs, bacteria, pollen which are allergic factors.
