This is How Air Purifiers Work

Everything we do, be it in our residences or work areas, always has its own outcomes.  Among the most concerning problem is the contamination of our breathable air.  Dust,smoke,virues and spores from fungi are some of the air contaminants.  If not removed from our air the contaminants cause harmful effects like respiratory diseases and destruction of the O-zone layer.

A device used to remove pollutants from the air is called an air purifier.  The benefits of using air purifiers are enjoyed largely by people with 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. Work in such industries has, therefore, been made possible and less hazardous.

Air purifiers have been known to exist since the nineteenth century. Back then, the air purifiers at were basic and their efficiency low. Technological advancements have seen tremendous improvement made on the working of the purifiers. They also come in different sizes for both homes and industries. 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. 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. Effective air purifiers may become uncomfortable if too noisy. Know more about air purifier at

Another thing to consider is how frequent the purifier needs replacement of parts. Lastly, consider how much power the air cleaner consumes as it works or on standby.

Purifiers using heat to clean the air are called thermo air cleaners. 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. Contaminants like dust not affected  by heat cool down and settle and thereby are not released from the purifier.

Next we have the ultraviolet air purifiers. These will have ultraviolet rays in their systems. Air is freed from contaminants by subjecting the contaminants to rays that make them inert. Though not retained in the filter, the contaminants are released but in an inactive state thereby pausing no danger.

We also have another type of qnet net air cleaners called the High Efficiency Particulate Arrestance (HEPA) air purifiers. 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. Adsorption is applied by these filters to clean air. Non-solid matter in the air is converted into solid matter. The HEPA air purifier can be used together with this air cleaner.
