Everything we do, be it in our residences or work areas, always has its own outcomes. Breathable air being polluted is among the very major things that concern us. Air pollutants will be like dust, Fungal 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.
A device used to remove pollutants from the air is called an air purifier. 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. Safety is thereby increased in these industries.
The use of air purifiers has been known to date back to the nineteenth century. Back then, the air purifiers were basic and their efficiency 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. The working mechanisms of the air purifiers is what we will focus on in this discussion.
There are some three things to consider before going for a purifier. Air purifier manufacturers lure their consumers by use of these three things. The noise emanating from the purifier is one thing. Effective air purifiers may become uncomfortable if too noisy.
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.
Heat is used by thermo air cleaners to remove contaminats. 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. Air is cooled slightly before being released into the atmosphere for human use. Dust particles settle down during cooling before air is released.
The other type of air cleaners are 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 pollutants will not be removed entirely but inactivated such that they are harmless.
High Efficiency Particulate Arrestance (HEPA) air purifiers are the other type of air cleaners. They work by use of trapping materials. 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. The filter, therefore, requires replacement of parts based on the amount of pollutants present in the air cleaned. This filter is compatible with almost all the other purifiers.
Lastly, the other common type of air purifier is the activated carbon air cleaner. The filter uses the adsorption technique to clean air. Gaseous contaminants are adsorbed and translated to solid materials. The HEPA air purifier can be used together with this air cleaner.
