Premium Cabin Air Filter of Honda to Cut COVID19 Risk
Honda is now offering a new premium cabin air filter which is highly effective at capturing a wide range of harmful germs, allergens and even viruses related to significant health problems, including infection risks associated with the SARS COV-2 virus. The Honda premium cabin air filter was developed in cooperation with Freudenberg and is offered as a new Honda genuine spare part, as an alternative to the standard Honda pollen filter. This new premium cabin air filter provides active protection by significantly reducing the concentration of viral aerosols. This is achieved by a unique multi-layer design that effectively filters, captures and suppresses noxious environmental gases as well as inorganic and biological particles and aerosols.
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.
