Repercussions will always come to us due to our everyday work. Air pollution is one of the most disturbing problems we have. Air pollutants will be like dust, Fungal spores, viruses and smoke. Diseases to the respiratory system and destruction of the O-Zone layer are some of the effects of air contamination.
The air we breathe is rid of contaminants by devices we call air purifiers. The benefits of using air purifiers are enjoyed largely by people with allergies. These peoples conditions may deteriorate due to the presence of contaminants in the air. Factories releasing dust or smoke have air purifiers made for them too. 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. Technological advancements have seen tremendous improvement made on the working of the purifiers. Purifiers find their use in homes and industries. What determines how complex a purifier is the kind of the contaminants to be targeted and the magnitude of pollution. The working mechanisms of the air purifiers is what we will focus on in this discussion.
Prior to any air purifier purchase, one needs to consider three things Consumers are attracted to the air cleaners based on 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.
Frequency of part replacement is the next thing one considers. 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.
Ultraviolet based air purifiers are the other types of air purifiers. Ultraviolet rays are found within the purifiers. The air pollutants are eliminated from the air by being sterilized by the rays. Though not retained in the filter, the contaminants are released but in an inactive state thereby pausing no danger.
We also have another type of air cleaners called the High Efficiency Particulate Arrestance (HEPA) air purifiers. These use the simple trapping mechanism. This, therefore, makes the purifier ideal for cleaning air polluted with physical contaminants. Dust and any physical materials like pollen are trapped within the cleaner. The filter, therefore, requires replacement of parts based on the amount of pollutants present in the air cleaned. An advantage is that it can be used together with the other purifiers.
Lastly, the other common type of air purifier is the activated carbon air cleaner. Its working applies adsorption to clean air. Gaseous contaminants are adsorbed and translated to solid materials. The purifiers can also be used in collaboration with the HEPA air filter.
