Despite looking very different from one another, almost all air purifiers work the same way. A standard model has two openings – one in front and another one towards the back – that the air passes through. Between these are several screens or filters that are used to strain different types of microorganisms.
Now, why is there a need for multiple filters to be present in a singular device?
Well, there are several kinds of microns found in the air that we breathe; each one varying in size, shape, and density. The main reason why there needs to be several of these screens present is to effectively eliminate all those particles.
Each filter plays a significant role in this entire cleansing process. Generally speaking, the absence of one or more of these would mean that the air is not completely sanitized. Here are the different layers and the important functions that they serve.
This filter is designed with specialized absorbent pores that allow different kinds of gases, such as smoke, chemicals, and odors from cooking, to pass through. Once this happens, the purifier releases a carbon element that traps these gases inside and consequently eliminates. While this isn’t technically a purifying technique per se, it does help your home smell better by neutralizing any unwanted odors.
The HEPA, or high-efficient particulate air, is a secondary layer and is in-charge of trapping microns such as pollen, dust mites, or pet dander. These irritating microorganisms are responsible for causing allergic reactions to humans. Additionally, these can also be the primary cause of asthma attacks.
Similar to the first layer we discussed, most HEPA filters are equipped with an activated carbon feature. Carbons are released that causes these particles to get stuck and eventually eliminated. While this cannot completely eradicate all airborne pathogens, it is strong enough to those that are 0.3 microns in size and remove 99.97% of them.
This filter can locate particles as small as 0.1 microns by releasing a steam of negative ions into the air. The little specks are then positively charged, absorbed into the field, and subsequently get stuck on a metal plate found on this layer. Once you open up the air purifier and take this filter out, you’ll see several black spots, which are the remnants of these harmful microorganisms.
The ionized filter can be used to counteract bits that have not been completely destroyed by the other strains. Just be sure to regularly clean this because it can leave fragments of ozone that can be harmful to humans.
The final layer is arguably the most powerful, and that is the UV light air filter. This is responsible for eradicating dangerous viruses, molds, or bacteria that float around in the air. Strong UV lights proceed to break the molecular bonds of these particles as they pass through the air purifier. As a result, the air that you and your family will breathe at home will be free from any contaminants.
Air is something very integral to human life, which makes an air purifier an important machine to have at home. Understanding how it works and the different processes that it undergoes is crucial to help us maximize its function.
Through this short article, I hope you learned something that will lead you to improve how you use this at home.
Personally, I have always been fascinated with home items. I’ve learned long ago that when buying these products, there needs to be a balance between functionality and creativity. Otherwise, they get old and boring, and I don’t get to use them as much.
