Our day to day activities at homes and industries come with a variety of repercussions. Among the most concerning problem is the contamination of our breathable air. Materials contaminating our air include dust, fungus spores, viruses and smoke. 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. Among the people that benefit most from using air purifiers are people with diseases like Asthma or allergies. Presence of contaminants in the air may worsen the conditions of such people. Factories releasing dust or smoke have air purifiers made for them too. This makes working in these industries possible and safe.
The use of air purifiers has been known to date back to the nineteenth century. The efficiency of the cleaners back then was low. Technological advancements have seen tremendous improvement made on the working of the purifiers. Depending on whether they are to be used in homes or industries, air cleaners come in different sizes. 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. These three things have been used by air purifier manufacturers to attract potential consumers. The noise emanating from the purifier is one thing. Noisy air purifiers are uncomfortable to use however effective they may be.
Frequency of part replacement is the next thing one considers. Consider at last, the power intake of the air cleaner both while in use or on idle mode.
Thermo air purifiers use heat to clean the air. The air passing through them is heated. Before passing out, air contaminants like bacteria, viruses or fungi are killed in the purifier. Before releasing air to the atmosphere, it is cooled slightly. Contaminants like dust not affected by heat cool down and settle and thereby are not released from the purifier.
The other type of air cleaners are the Ultraviolet air purifiers. They have systems equipped with ultraviolet rays. 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.
High Efficiency Particulate Arrestance (HEPA) air purifiers are the other type of air cleaners. Materials to be eliminated are trapped within the purifier. If air is contaminated with physical contaminants such as dust, this is the ideal purifier. Dust and any physical materials like pollen are trapped within 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. Volatile materials are trapped and converted into solid matter. To improve efficiency, these cleaners can be used together with the HEPA air cleaners.
