In Brief

The Hand Tree concept design intakes dirty air and cleans it, creating a healthier atmosphere.

Semi-finalist in the Electrolux Design Lab competition, Alexandr Kostin’s concept bracelet, the Hand Tree is a wearable filter that cleans the air surrounding a person. Kostin believes that if everyone wears his invention, we will have an army of mobile air purifiers cleansing the Earth.

The Hand Tree is made from a bioplastic shell and a fake leather bangle, which feels comfortable against the skin. It contains a changeable carbon filter, a chargeable batter and an OLED screen. The logo changes color in response to the condition of the filter and a light on the shell indicates the air quality. The concept is inspired by the natural air purification system of plants, taking in contaminated air and returning clean air. The wearer even has the option to insert a perfumed capsule, so their personal space can be fragrant.
