On Purifiers: My Thoughts Explained

Understanding the Working of Air Purifiers

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. Diseases to the respiratory system and destruction of the O-Zone layer are some of the effects of air contamination.

A device used to remove pollutants from the air is called an air purifier. 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. 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. Cleaners used in those yester years had little efficiency. 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. Complexity of an air purifier depends on the target contaminants and the extent 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. 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.

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.

Purifiers using heat to clean the air are called thermo air cleaners. The air passing through them is heated. The heat kills any contaminant be it bacteria, virus or fungi before passing out. Before releasing air to the atmosphere, it is cooled slightly. Dust particles settle down during cooling before air is released.

The other type of air cleaners are the Ultraviolet air purifiers. Ultraviolet rays are found within the purifiers. The air pollutants are eliminated from the air by being sterilized by the rays. 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. Materials to be eliminated are trapped within the purifier. It is mostly used to clean air contaminated by physical contaminants like dust. 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.

Finally, we have the activated carbon air purifier. Its working applies adsorption 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.
