Our day to day activities at homes and industries come with a variety of repercussions. Air pollution is one of the most disturbing problems we have. Materials contaminating our air include dust, fungus 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 layer in the atmosphere called O-Zone layer.
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. Air cleaners have also been made for industries emitting fumes, dust or smoke. This makes working in these industries possible and safe.
Air purifiers have been known to exist since the nineteenth century. The efficiency of the cleaners back then was low. Since then, they have become improved and with different working mechanisms. 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.
Prior to any air purifier purchase, one needs to consider three things Consumers are attracted to the air cleaners based on these three things. The noise emanating from the purifier is one thing. Effective air purifiers may become uncomfortable if too noisy.
Also put into consideration the duration of time it takes before replacing parts of the purifiers. 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. Heating air passing through the cleaner is how they work. Before passing out, air contaminants like bacteria, viruses or fungi are killed in the purifier. Hot air is not released immediately but released after being cooled. Dust particles settle down during cooling before air is released.
Next we have 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. The pollutants will not be removed entirely but inactivated such that they are harmless.
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. The cleaner traps any physical material in the air within itself. Depending on the amount of contaminants in the air this filters requires replacement of parts. This filter is compatible with almost all 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 HEPA air purifier can be used together with this air cleaner.
