Our day to day activities at homes and industries come with a variety of repercussions. Breathable air being polluted is among the very major things that concern us. Dust,smoke,virues and spores from fungi are some of the air contaminants. Diseases to the respiratory system and destruction of the O-Zone layer are some of the effects of air contamination.
Air purifiers are devices made to remove contaminants from the air we breathe. People with diseases like asthma and allergies benefit more from the use of air purifiers. Air with pollutants may worsen the health of these people. 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. Discussed below are some of the mechanisms by which these purifiers work.
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. The amount of noise released by the air purifier is the first thing one considers. Effective air purifiers may become uncomfortable if too noisy.
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.
Purifiers using heat to clean the air are called thermo air cleaners. Working mechanism involves heating air passing through them. Bacteria, virus or fungi are killed by the heat before passing out of the cleaner. Hot air is not released immediately but released after being cooled. Dust particles settle down during cooling before air is released.
The other type of air cleaners are the Ultraviolet air purifiers. 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.
High Efficiency Particulate Arrestance (HEPA) air purifiers are the other type of air cleaners. Materials to be eliminated are trapped within the purifier. It is mostly used to clean air contaminated by physical contaminants like dust. Particles like dust and dust are trapped and do not leave the cleaner. The filter, therefore, requires replacement of parts based on the amount of pollutants present in the air cleaned. Other purifiers can be used in conjunction with this air cleaner.
Finally, we have the activated carbon air purifier. Adsorption is applied by these filters 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.
