Researchers at the University of Bath have unveiled a groundbreaking air purifier design, utilizing FOAM3R filter technology, that not only offers virus-stopping performance but also boasts a zero harmful waste feature.
The FOAM3R technology, patented by the University, serves as a highly adaptable disruptor for microbial, CO2, and volatile organic compound (VOC) odor removal.
Revolutionary FOAM3R filter technology
The FOAM3R technology proves to be versatile, finding applications in various settings such as aircraft cabins, in-car air filters, ship and boat cabins, residential heating, ventilation, and air-conditioning, as well as home air purifiers and respirator and breathing apparatus.
The innovative foam, comprising high-temperature polymer and active media, employs selective adsorbents to capture contaminants and antibacterial agents to combat microbes.
Lightweight and moldable, the foam is energy-efficient and incorporates active metals, ensuring a remarkable 99.999 percent efficiency in removing common bacteria and viruses.
Tailored composition for enhanced VOC capture
This breakthrough foam features a tailorable composition, enabling targeted capture of a wide range of small to large VOCs. This includes compounds responsible for unpleasant odors and others that may pose harm to human health.
Additionally, the FOAM3R technology demonstrates high-performance removal of CO2, further enhancing its efficacy in creating a healthier living environment.
The home air purifier design, currently in the prototype stage, utilizes two cylindrical columns of FOAM3R material. During operation, one column purifies the air, while the other undergoes a ‘regeneration’ process through heating, restoring the foam’s sorbent properties.
This unique process not only eliminates collected pollutants and microbial debris but also recovers volatile components through cooling and condensation. The recovered liquid is safe to dispose of.
Environmentally friendly manufacturing process
FOAM3R is created through a simple one-step manufacturing process, offering the advantage of easy shaping into various form factors. Remarkably, it can be retrofitted into existing technology, providing a sustainable alternative. Furthermore, it outshines comparable carbon-granule-based air purification systems in terms of energy efficiency.
Professor Semali Perera, from Bath’s Department of Chemical Engineering, expressed optimism about the air purifier design and FOAM3R technology, stating:
“We have created a highly efficient design, with none of the disposable cartridges or waste that we see in many commercial air purifiers, so there are several benefits to what we’ve created. Our next step is to engage potential commercial partners with the requisite expertise to bring our invention to the market.”
This innovation could mark a significant stride in air purification, offering a sustainable and efficient solution with potential applications across various industries.
The University of Bath’s innovative FOAM3R technology is poised to redefine the landscape of air purification, setting a new standard for effectiveness and environmental responsibility.
