Various Air Filters Working Mechanisms
Everything we do, be it in our residences or work areas, always has its own outcomes. Air pollution is one of the most disturbing problems we have.Materials contaminating our air include dust, fungus spores, viruses, and smoke.If not removed from our air the contaminants can cause harmful effects like respiratory diseases and destruction of the O-zone layer.
A device used to remove pollutants from the air is called an air purifier. People with disease like asthma and allergies benefit more from the use of air purifiers. Air with pollutants may worsen the health of these people.Air cleaners have also been made for industries emitting fumes, dust or smoke.This makes working in these industries possible and safe.
Air filters have been known to exist since the nineteenth century.Back then, the air cleaners were basic and their efficiency low. Technological advancements have seen tremendous improvement made in the working of the air filters.They also come in different sizes for homes and others for industries. What determines how complex a purifier is what contaminant is to be targeted and the magnitude of pollution.We will, therefore, look at some mechanisms by which these air cleaners work.
Considerations, however, have to be put into three things before opting for an air filter. Consumers are attracted by air cleaner manufactures based on these three things. How much noise is given out by a filter is the first thing. Effective air filters may become uncomfortable if too noisy.Another thing to consider is how frequent the filters need replacement of parts. Consider at last the power intake of the air cleaner both while in use or on idling mode.
Thermo air filter use heat to clean the air. Heating air passing through the filter is how they work.The heat kills any contaminant be it bacteria, virus or fungi before passing out. Before releasing air into the atmosphere, it is cooled slightly.As the air is cooled, dust particles not affected by the heat are settled and therefore do not flow out.
The other type of air cleaners are the Ultraviolet air filters. They have systems equipped with ultraviolet rays.The rays are used to sterilize any foreign material present in the air we breathe.Though not retained in the filter the contaminants are released but in an inactive state thereby pausing no danger.
Next we have the (HEPA) air filters. They work by use of trapping materials. If air is contaminated with physical contaminants such as dust, this is the ideal filter.Dust, and any physical materials like pollen are trapped within the cleaner. Depending on the amount of contaminants in the air these filters require replacement of parts.This filter is compatible with almost all the other filters.
Finally, we have the activated carbon air filter among the most used cleaners. Its working applies adsorption to clean air. Gaseous contaminants are adsorbed and made solid materials. The HEPA air filter can be used together with this air cleaner.
