Why air purifiers are dangerous to health

To conduct the experiment, the scientists purchased four air purifiers that cost between $ 65 and $ 400. The devices were equipped with physical and chemical cleaning technologies. They then placed the equipment in a special chamber in which they purified the air from two types of VOCs: toluene and limonene.

It turned out that out of four devices after 60-90 minutes, only two removed both VOCs, and the remaining two removed only limonene. That is, the cleaning speed of the devices also varied, and significantly. In addition, chemical compounds formed during the purification process were discovered, including formaldehyde and acetone.

It is known that exposure to certain VOCs can cause cancer or impairment of lung, liver or kidney function.
