Air purifiers are essential devices for improving indoor air quality. They usually consist of a filter, or several filters, and a fan that sucks in and circulates the air. As air moves through the filter, contaminants and particles are captured, and clean air is expelled into the living space. Filters are typically made of paper, fiber (often fiberglass), or mesh, and require regular replacement to maintain efficiency.
Air purifiers are commonly marketed as beneficial to allergy sufferers and asthmatics, and to reduce or eliminate secondhand smoke. Growing research has shown that adding an air purifier can make a big difference in your health and quality of life. Whether it's to prevent heart disease or to help students in school, air purifiers play an important role. So, let's explore 10 reasons why everyone needs an air purifier.
1.Removes Pollutants from the Air
When indoor air is drawn into the
air cleaner, it passes through a filter inside it.
Filters capture air pollutants, such as dust, and then push clean air into the room. Some purifiers are designed to remove specific types of contaminants, and others eliminate gases.
2.HEPA Filters
In the 1950s, HEPA filters were marketed as highly efficient air filters, after being used in the 1940s in the Manhattan Project in the United States to control radioactive contaminants in the air. HEPA filters are designed to capture particles as small as 0.3 microns.
3.Carbon-Based Filters
This carbon filtration method uses a highly porous form of carbon to trap chemicals and recycle fresh air back to the room.
4.Improves Air Quality
An air purifier can act as a supplement to a filter and other strategies to help remove particles from the air.
5.Remove Wrappers
Almost all air purifiers arrive with their filters wrapped, and almost all have stickers on the machine or warnings on the leaflet to remove the wrappers, but it's still a common mistake.
6.Noise Level
An air purifier, by its nature basically a fan and a filter, is noisy, especially at higher speeds.
7.Automatic Adjustment
Depending on what the manufacturer determines as “bad enough air quality”, an automatic adjustment can allow the air in your home to be heavily loaded with particles before starting the purifier.
8.ACH Rating
The ACH rating refers to the number of times per hour the entire volume of air in the room is filtered.
9.HEPA Filters
Most household air purifiers contain HEPA filters, designed to capture all of these contaminants and thus breathe clean air.
10. Passive Cleaners
Passive cleaners are more efficient, since all dust and particles are permanently removed from the air and accumulate in the filters.
Conclusion
Air purifiers are essential devices for improving indoor air quality. They can act as a supplement to other strategies for removing pollutants from the air and help you breathe clean air.
