Abstract
AbstractIn this study, we propose a new design for a microchannel filter. The closed indoor environments with which we interact daily are sources of diseases for the respiratory system of human beings. Recommendations for the design of microchannel filters for indoor air purification are proposed, implementing low-cost microequipment technology (MET) for the manufacture of the elements that constitute a microfiltration system. For the microchannel filter production, we proposed to use MET, which is a miniaturization technology and can reduce manufacturing costs. The microchannel filter was 3.75 cm in radius with a thickness of 3 mm. It had a triangular profile and a helical trajectory. It was designed, manufactured, and tested for two profile dimensions. The main purpose was to reduce the pressure drop of the air flow through the filter. We described the air flow simulation for the microchannel filter using SolidWorks. A prototype microchannel filter was constructed, which underwent manufacturing tests. It is possible to clean the microchannel using water flow, which allows us to maintain the filtration quality within an optimum range of contaminant removal.

We propose to develop air filters manufactured with the microequipment technology (MET) [6]
We have proposed and previously used MET for the development of the minifilters and microfilters
Summary
It is necessary to clean the air to avoid health problems. Every year, air pollution has been increasing. According to the studies carried out by Mukund et al [11], the levels of VOCs in the air inside automobiles can be up to eight times higher than that in the vicinity of the monitored space, representing an important health problem. In the United States, several cases of death from carbon monoxide poisoning are reported, in adverse situations, such as after a hurricane or flood, when electric energy generators based on hydrocarbons are used in interior spaces without adequate precautionary measures This is because a ventilation system is required to evacuate the emissions of combustion to ensure good quality air inside the house [14].
