How does a HEPA filter suitable for a Corona air purifier work?
The constant spread of COVID-19 has made people think about keeping their homes clean. One way to do this is to purify the air. Some companies have gone so far as to claim that air purifiers can stop some respiratory illnesses in their path. But what is the right corona air purifier anyway? Are they air purifiers or just a filter? What is the type of air filter in this device? Can they help fight the coronavirus?
In this article, we are going to tell you about the HEPA filter and the HEPA filter in the Corona air purifier.
HEPA Filter What is a suitable Corona air purifier ?
HEPA or High Efficiency Particulate Air is a filter that purifies air particles with high efficiency. This filter is made of interwoven and compressed fibers of fiberglass, straw, mat, cotton and similar materials.
It remains to be seen when we will start using the HEPA filter. But to continue the article, it is necessary to say that the story of using the HEPA filter dates back to World War II. At that time, scientists built a filter to prevent the inhalation of particles released by the atomic bomb, which today is called the HEPA filter.
How does the HEPA filter purify the air ?
HEPA filter The air purifier has three different mechanisms for air purification. These three different mechanisms cause most polluting particles, or in other words, 99% of the particles to fall into the filter trap and purify and purify the ambient air.
The three mechanisms are as follows:
Mechanism of trapping thick particles in HEPA filter
Airborne particles have different diameters. A suitable filter should trap suspended particles of different diameters. The HEPA filter in a suitable Corona air purifier absorbs particles larger than one micron, which are still much smaller than those seen with the naked eye, due to the very dense texture of their fibers. However, it must be said that in this mechanism, the air flow also changes.
The mechanism of blockage of very small particles in the HEPA filter
We described the mechanism for trapping thick particles in the previous section. But how does a HEPA filter trap very small particles? As the airflow passes through the filter, the fine particles are trapped along the fibers along with this flow and trapped.
The mechanism of virus blockage in the HEPA filter of a suitable corona air purifier
What distinguishes the HEPA filter from a suitable corona air purifier from other simple filters is the mechanism by which very, very small particles, such as viruses, are blocked. In this method, pollutant particles that are very small in size, by constantly colliding with gas molecules, change direction and travel in an irregular path. Due to this collision, their speed decreased and they easily fell into the trap of HEPA filter.
Does the HEPA filter absorb the corona virus?
However, the question arises for us: does the HEPA filter of the air purifier trap the corona virus? According to a study by a number of scientists on the HEPA filter in air purifiers, if it has the right quality, this filter is able to absorb particles with a size of 3 to 20 nanomicrons. That means something about 3 to 20 times smaller than the Corona virus!
This filter uses the Diffusion property to trap the virus. That is, particles such as the corona virus and… change direction due to continuous impact with gaseous molecules and follow an irregular path, and this irregular path causes it to be trapped and easily fall into the trap of HEPA filter.
Is the HEPA filter washable in a suitable Corona air purifier?
You may have heard that some Corona air purifier vendors tell you that there is a HEPA filter in their appliances. But the fact is that the HEPA filter does not clean after its capacity, even if it is washed.
Because the very, very small particles in this filter are not removed by washing with water and liquid, and you have to replace the filter of the device. By changing the filter, the device achieves its previous proper performance.
What devices have HEPA filters?
There are several air purifiers on the market. But it is necessary to say that one of the best examples available in the market is a product that is the product of Iranian scientists, namely Danesh Bonyan Sameh. The company has been able to produce an air purifier that is suitable for the corona and can purify and purify the ambient air. In such a way that being in that environment is no longer dangerous and stressful.
Corona air purifier suitable for hearing filtration company has three stages and can purify and purify the air of office, home and commercial environments.
