To lower the infection risk in the vehicle cabin, it is generally recommended to increase the fresh air supply to reduce the concentration of aerosols.. In recirculation mode, removing viruses from the air largely depends on the efficiency of the filtration system and the air exchange rate.
The first two microfibre layers of the Honda premium cabin air filter capture most ultrafine aerosols, dust and pollen while the third layer, made of activated carbon, is responsible for the adsorption of harmful pollution such as particulates and acid gases. An innovative fourth bio-functional layer coated with the active substance of fruit extract then effectively inactivates captured viral aerosols and prevents them from being released back into the cabin air. This has been conclusively proved by a comprehensive series of tests conducted in collaboration with the Austrian Research Institute OFI.
Coronaviruses are spread in droplets produced when those affected sneeze, cough or breathe and can remain infectious on surfaces for hours or even days. Wind disturbances, temperature changes and humidity can all cause that these particles become airborne again, at which point they can be picked up by the filter.
The fine particle filtration layers provide improved protection against virus transmission in comparison to standard filters. They demonstrably separate not only droplets (> 5 μm), but also critical viral aerosols (droplet nuclei significantly below 5 μm). The new Honda premium cabin air filter can trap more than 90 percent of viral aerosols. In addition, an innovative second step inactivates almost 100 percent of the captured viral load via a bio-functional layer impregnated with the active substance of fruit extract.
The SARS-CoV-2 virus is just the latest of an unbroken line of viruses stretching back through human history that impact on human health. In terms of mitigating risk while travelling in motor vehicles, the advanced Honda premium cabin air filter offers one of the best protections available in the market.
