Solaga’s Alwe Air Purifier

Germany-based startup Solaga is dedicated to purifying indoor air. Founded in 2017, its main product is a small wall decoration named Alwe. Alwe looks like an inconspicuous, minimalist framed art piece, but its function can improve the health of those in the home or office. The wall panel is made of microalgae that absorb pollutants and purifies the air.

While Alwe has the aesthetic of art, the frame contains small holes in the sides to let the air from your home into the algae area. They then bind to and fix the air pollutants such as carbon dioxide and carbon monoxide. Solaga’s research shows that Alwe is also able to absorb nitrogen oxides. With further research, the company hopes to expand the algae’s filtration ability to VOCs and SO₂.
