One Article Helps You Know What Exactly HEPA Air Purifier Can Do

Air purifier machine is a common household equipment, while you might haven’t known what exacty it’s helping you to clean. This article will guide you to know  powerful strengths of the air filtering machine, Smell removal, Dust removal, Allergies removal. First you might want to know how does the air purifier work.

How Does HEPA Air Purifier Work?

Air purifiers refer to equipment that can adsorb, decompose or convert various air pollutants and effectively improve air cleanliness. At present, household and commercial air purifier for home are mainly used to remove indoor air pollution. There are four types of HEPA, they are different on work efficiency.

 

Four Types of HEPA

True HEPA

  • Best type
  • Captures the widest range of contaminants
  • 99,97% of particles as small as 0.3 microns

Essentially, a True HEPA filter is the best type because it’s certified to capture 99.97% of particles smaller as 0.3 microns.

HEPA-type

  • Captures fewer contaminants
  • Particles 2 microns and larger
  • 500% difference in efficiency compared to a True HEPA filter.

On the other hand, Filters labeled as HEPA-like, HEPA-type, or HEPA can only capture particles. So when you are considering about to buy an air purifier, it’s better to ensure it applies a true HEPA filter. You may now wonder where to apply it, keep on reading.

 

How Small of Particles Can True HEPA Work On?

0.3 microns (µm). HEPA, also names as high efficiency particulate air, is a series of pleated mechanical air filter. This type of air filter can theoretically remove at least 99.97% of dust, pollen, mold, bacteria, and any airborne particles with a size of 0.3 microns (µm).  

True HEPA filters are usually constructed from borosilicate glass or plastic fibers arranged in a mat of randomly placed fibers. However, HEPA filters do not work like a sieve which captures particles greater than a specific size and allows the smaller ones to pass through. With a HEPA filter, particles are trapped by sticking to a fiber through diffusion, interception, or impaction.

 

So then here comes the next question—how big is a micron? (symbol: µ) Well, one inch = 24500 microns. Here is a short list of common items for comparison.

 

Bacteria:

1-10 microns

Very Fine Sand:

65 microns

Human Hair:

17-181 microns

Dust Mites:

100-300 microns

Copier Toner:

0.5-15 microns

Pollen:

10-1000 microns

Tobacco Smoke:

0.01-4 microns

Viruses:

0.005-0.3 microns

 

 

Process of HEPA Air Filtration

Step 1

In the process of air purification, the toxic and harmful gases entering the air inlet are firstly pre-filtered (ie, the initial filtration stage). The filter materials in this stage are generally sponge filters, PP nylon filters, antibacterial filter cotton, and sponges. Composite materials with activated carbon, etc. 

 

Among the filter departments, the PP nylon filter mesh is made of nylon mesh. The filter material is made of PP fiber textile and formed into one body. The outer frame is aluminum alloy, or a galvanized frame is used to support it with iron wire. The nylon mesh is tightened with a lining frame and then loaded into the frame.

 

Antibacterial filter cotton can remove microorganisms such as dust, mold and bacteria. If it is a composite material, such as activated carbon, it has already begun to initially remove odors, formaldehyde and other harmful gases.

 

Step 2

Secondly, enter the second layer (high-efficiency filter layer), which is a HEPA component (High efficiency particulate air Filter), and air filtration and purification are mainly made of fiber filter material. The principle is that when the air passes through the air filter made of fiber material, the air The particles in the filter are retained by the fiber filter material, so that the particles are separated from the air, so as to complete the further purification and filtration of the air.

 

Step 3

Finally, the sterilizing cotton and activated carbon filter can effectively sterilize, deodorize, and deodorize again, and re-filter the missing microorganisms and viruses in the air of the pre-filter layer, and finally output high-quality air for indoor residents to breathe.

 

Common Particles True HEPA Filter Remove

  • Odor Removal

Air purifier can remove odor. Alongside direct interaction to eliminate the source of smell, no matter mold or strong kitchen odor, true HEPA can help with odor removal. Membrane Solution technology is the one of the best choice that effectively volatile organic compounds (VOCs), which are the main airborne chemicals bad smells in your home. And what’s more, mold, bacteria and pet dander as well, can makes up unpleasant smells. Most of which are harmful to our health.

 

  • Dust Removal

Air purifier can remove dust. The number of layers of the nylon mesh can be determined according to the user's requirements. Its characteristics are good dust removal effect, acid and alkali resistance, good corrosion resistance, low resistance, light weight, moisture resistance, long life, etc. The pre-filter can remove large particles of dust suspended solids, pollen, large particles of mold, pet hair, etc.

Conclusion

Behind the greed for beauty is the abuse of these chemical materials. The problem of indoor environmental pollution is becoming more and more prominent. People have entered a period of indoor air pollution, but at the same time, human health awareness is also increasing. How to improve the home environment and breathe clean Air and healthy life are common problems faced by all countries in the world.
