The inner layer is made from a column of high-quality catalytic activated carbon that powerfully absorbs harmful gases such as formaldehyde and toluene as well as odors, offering long-term purification without producing unpleasant smells.
They have a new air purifier aswell, but no reviews yet. And since the xiaomi is the 3rd iteration, it is a good bet.
