Understanding the Working of Air Purifiers
Everything we do, be it in our residences or work areas, always has its own outcomes. Air pollution is one of the most disturbing problems we have. Dust,smoke,virues and spores from fungi are some of the air contaminants. 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. Among the people that benefit most from using air purifiers are people with diseases like Asthma or allergies. These peoples conditions may deteriorate due to the presence of contaminants in the air. There are air purifiers made specifically for industries whose wastes include dust or smoke. 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. Pollution levels and type of air contaminants determine how much complex the purifier will be. 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. Consumers are attracted to the air cleaners based on these three things. The amount of noise released by the air purifier is the first thing one considers. Noisy air purifiers are uncomfortable to use however effective they may be.
Another thing to consider is how frequent the purifier needs replacement of parts. Power consumption both on standby or in use is the last thing you should consider.
Thermo air purifiers use heat to clean the air. Working mechanism involves heating air passing through them. Bacteria, virus or fungi are killed by the heat before passing out of the cleaner. Before releasing air to the atmosphere, it is cooled slightly. Dust particles settle down during cooling before air is released.
Next we have the ultraviolet air purifiers. Ultraviolet rays are found within the purifiers. Air is freed from contaminants by subjecting the contaminants to rays that make them inert. The pollutants will not be removed entirely but inactivated such that they are harmless.
Next we have the High Efficiency Particulate Arrestance air purifiers. They work by use of trapping materials. This, therefore, makes the purifier ideal for cleaning air polluted with physical contaminants. The cleaner traps any physical material in the air within itself. 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.
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. To improve efficiency, these cleaners can be used together with the HEPA air cleaners.
