In these days it is easy to overlook even the simplest mechanisms which make our everyday life convenient and free of hassle. Something like air filtration pa is one of those innovative things that people for the most part turn a willingly blind eye to, but if one were to examine the historical elements correlated with air filtration along with what an air filter actually does a world of possibilities could open up to them as new information is gathered about the process of how filtering air works. In this article that is exactly what we will be discussing in detail.
What exactly is air filtration? Well according to Wikipedia an air filter is required for this process to occur. Inside of the filter is a porous substance that catches microscopic germs and visible dust particles to clean the air of anything toxic and potentially unhelpful. This process is so efficient that even odors are stuck in the web of the filter thus allowing for the air to not just be cleaner but to smell better as well. These technologies are applied in the most crucial of areas such as ventilation systems and engines. Depending on the environment and building type the process of air filtration will differ and vary greatly. There are even instances of mechanics that use electric shock to attract dust particles in order to more efficiently clean the surrounding space. Other such facilities like a medical clinic must use a device called HEPA which is a filtration system mandated by law to be installed into those specific constructs. To prioritize the order in which these filters are installed course filters are used as the primary device for such a task before the secondary fine filters are installed as an effective second run through.
What is the history of air filtration? Well according to documentation the first air filtration device which was utilized was a face mask worn in the sixteenth century. Later in the seventeenth century it was surmised that a water dipped cloth could potentially protect sailors from inhaling anything that constituted a toxic fume. This idea became popular among miners with the cloth actually being a piece of wet wool with a clip attached to it. The cupped shape of the mask did take place soon after the invention of the wool mask. In the nineteenth century it was the military that took it up a notch and made the first HEPA filter because they believed that this would mitigate the risk of them losing men to chemical warfare. Even though this proved to be a massive step of innovation the HEPA filter had unfavorable attributes associated with it such as its susceptibility to fire and the fact that it contained trace amounts of asbestos. This was soon fixed by constructing the HEPA filter with more fire resistant material and lining the filter with a different parchment which did not contain asbestos.
Yes the stages of the air filter both served in its effectiveness and variety. Through trail and error we found the foremost technology to keep our air clean where it most counts.
