Bath team develops ‘zero harmful waste’ air purifier

Central to the purifier is FOAM3R filter technology which is described as a highly adaptable disruptor technology for microbial, CO2 and volatile organic compound (VOC) odour removal.

Patented by the University, FOAM3R can be used to produce multi-functional foam structures for applications including aircraft cabins, in-car air filters, ship and boat cabins, residential heating, ventilation and air-conditioning, home air purifiers and respirator and breathing apparatus.

The foam is comprised of high temperature polymer and active media such as selective adsorbents to capture contaminants and antibacterial agents to combat microbes. It is claimed to be mouldable and lightweight, energy-efficient and anti-bacterial, and the addition of active metals into the structure is said to make it 99.999 per cent efficient in removing common bacteria and viruses.

FOAM3R’s tailorable composition allows for targeted capture of small to large VOCs – some of which are responsible for unpleasant smells, while others can be harmful to human health – and high-performance removal of CO2.
