Repercussions will always come to us due to our everyday work. Breathable air being polluted is among the very major things that concern us. Air pollutants will be like dust, Fungal spores, viruses and smoke. If not removed from our air the contaminants 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. The benefits of using air purifiers are enjoyed largely by people with allergies. Presence of contaminants in the air may worsen the conditions of such people. There are air purifiers made specifically for industries whose wastes include dust or smoke. This makes working in these industries possible and safe.
Since the nineteenth century, air cleaners have been reported to have been in use. Cleaners used in those yester years had little efficiency. Different working mechanisms have since been incorporated into the air purifiers. They also come in different sizes for both homes and industries. Complexity of an air purifier depends on the target contaminants and the extent of pollution. The working mechanisms of the air purifiers is what we will focus on in this discussion.
Cosiderations have to be made concerning three things before opting for a purifier. Air purifier manufacturers lure their consumers by use of these three things. How much noise a purifier makes is the first thing. However effective an air purifier may be, loud noise is very uncomfortable.
Another thing to consider is how frequent the purifier needs replacement of parts. Lastly, consider how much power the air cleaner consumes as it works or on standby.
Heat is used by thermo air cleaners to remove contaminats. Heating air passing through the cleaner is how they work. Bacteria, virus or fungi are killed by the heat before passing out of the cleaner. 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.
Next we have the ultraviolet air purifiers. These will have ultraviolet rays in their systems. The rays are used to sterilize any foreign material present in the air we breathe. The filter makes air clean by sterilizing the pollutants and making them safe.
Next we have the High Efficiency Particulate Arrestance air purifiers. Materials to be eliminated are trapped within the purifier. This, therefore, makes the purifier ideal for cleaning air polluted with physical contaminants. Particles like dust and dust are trapped and do not leave the cleaner. Depending on the amount of contaminants in the air this filters requires replacement of parts. An advantage is that it can be used together with the other purifiers.
Finally, we have the activated carbon air purifier. Adsorption is applied by these filters to clean air. Gaseous contaminants are adsorbed and translated to solid materials. To improve efficiency, these cleaners can be used together with the HEPA air cleaners.
