Cardboard Cactuses To Clean The Air Around You
According to a journal article by Gabriele Candiani, Barbara Del Curto, Chiara Malloggi and Alberto Cigada, cardboard-based filters are effective in removing airborne bacteria in indoor environments.
Following up on the theory, Italian company Meta Material has created air filters made of recycled corrugated cardboard in shape of cactuses.
Called the ‘Cactusnext’, the purifiers clean the air with natural substances with almost no noise.
It contains a fan or two (depending on the size) and a removable filter with patented antibacterial treatment NextMaterials, and can be powered using a power adapter or a USB connection.
Moreover, it’s lightweight, eco-friendly, and inexpensive—retailing at a cost of US$26-52.
