Various Air Filters Working Mechanisms
Everything we do, be it in our residences or work areas, always has its own outcomes.Among the most concerning problem is the contamination of our breathable air. Air pollutants will be like dust, Fungal spores, viruses, and smoke. Failure to eliminate the pollutants from the air lead to adverse effects like diseases of the breathing system and damage to the protective layer in the atmosphere called O-Zone layer.
A device used to remove pollutants from the air is called an air purifier. The benefits of using air filters are enjoyed largely by people with allergies.Presence of contaminants in the air may worsen the conditions of such people.Air cleaners have also been made for industries emitting fumes, dust or smoke. Work in such industries has therefore been made possible and less hazardous.
Since the nineteenth-century air filters have been reported to have been in use. Efficiency of the cleaners back then was little.Since then, they have become improved and with different working mechanisms.They also come in different sizes for homes and others for industries. Pollution levels and type of air contaminant determine how much complex the purifier will be. The working mechanisms of the air filter is what we will focus on.
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.The noise emanating from the filter is one thing. However effective an air filters may be, loud noise is very uncomfortable.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.
Filter using heat to clean the air are called thermo air filter.The air passing through them is heated. Before passing out, air contaminants like bacteria, viruses or fungi are killed in the filter.Air is cooled slightly before being released into the atmosphere for human use.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 air pollutants are eliminated from the air by being sterilized by the rays. The pollutants will not be removed entirely but inactivated such that they are harmless.
Next we have the (HEPA) air filters. Materials to be eliminated are trapped within the filter.t is mostly used to clean air contaminated by physical contaminants like dust.Dust, and any physical materials like pollen are trapped within the cleaner. Parts of the air filter may require regular servicing though this depends on how polluted the air is. Other filters can be used in conjunction with this air cleaners.
Lastly, another common type of air filter is the activated carbon air cleaner. Its working applies adsorption to clean air. Non-solid matter in the air is converted into solid matter.The purifiers can also be used in collaboration with the HEPA air filter.
