Air filter spray with metal nanoparticles kills 99% of germs

Researchers from the Spanish research center IMDEA Materials Institute together with air filter manufacturer Venfilter have developed a solution that can destroy microbes while filtering indoor air. The optimal substance for this purpose is active metal oxides, but there are many questions about the best form in which to use them. In the current experiment, the choice was given to a spray with metal nanoparticles.
The idea is to create a renewable coating on the inlet pathways of typical filters that will kill microorganisms. To do this, the spray is sprayed on the filter, about every few days, similar to household cleaners. To create a filter with a film of metal oxide is not commercially profitable – not all rooms need such protection, it is selective and the consumer himself determines the need for such costs.
