The motivation of Activated Carbon Filter development is the need to compare the enhanced efficiency between fiber filters and Synthetic air filter. However, any filtering innovation should depend on activated carbon filter working principle. This is true even though the devices are among different filter classes. As a matter of fact, influence of the ion concentration on Activated Carbon Filters is also investigated during the comparison. The study can be conducted in a full scale chamber that is constructed in accordance with the European filter standard. To be more specific, a HEPA filter is used upstream to provide clean air. On the other hand, downstream the HEPA filter can be promoted by an atomizer so that negative ions can be generated by Activated Carbon Filter. This is because the carbon fiber ionizer has the working voltage of 7 kV. What is more, the ion concentration can be measured by an ion meter with an average ion concentration. The corresponding activated carbon filter working principle faces velocities of the two air flow. Thus, we can significantly reduce the outdoor-to-indoor transport of harmful particles over several years of operation. That is why Activated Carbon Filter is regarded as a wonderful substrate for filter applications. Previous studies have shown that activated carbon filters working principle can be used for field emissions so as to improve the mechanical properties of ceramic materials. In our case, we propose that whiskers grown on carbon fabric substrate will greatly enhance Activated Carbon Filter efficiency by reducing the pressure drop. At the same time, we have found that they can trap small particulate matter. On the basis of activated carbon filter working principle, whiskers have been produced by several processes such as the reduction of silica and reactions between chemical vapor depositions.
This can be achieved as long as we use a metallic catalyst like Ni or Fe and among these processes, chemical vapor deposition methods have been widely used in Activated Carbon Filter. This is because they can form homogeneous whiskers in the infiltration process. At the same time, we need to analyze the properties of Activated Carbon Filter according to activated carbon filter working principle. In other words, we need to consider the change in mean pore size, efficiency of the particle trap, and Activated Carbon Filter permeability. The good news is that the substrate is flexible so there is no shape restriction in filter manufacturing. What is more, the carbon filter downstream in air passing might change after 5 years of continuous operation. With the help of Activated Carbon Filter, perceived air quality has been improved along with incorporated filters under identical conditions over three months.
