Nowadays, a HEPA filter has become an indispensable attribute in the design of hoovers to avoid air pollution. Also, they are used in cleaning systems (ventilation systems, air conditioners). The main task of the device is to capture tiny dust particles 0.01-1 microns in size. When appearing in the human lungs, such things can negatively affect health and cause the emergence of allergies and other related diseases. If you’re interested in such products, you can buy them on site.
How does it work?
When cleaning, a vacuum cleaner sucks in large and small rubbish from one side and breathes out a stream of polluted air on the other side, as if moving dust from one place to another. The HEPA filter comes to rescue when it’s time to retain them. It is installed at the outlet of the hoover’s air stream.
Appliances of this manufacturer are a kind of high-efficiency products. It is also called a fine cleaning device. It is made of fibrous materials with a fiber diameter of 0.65-6.5 microns, which are randomly placed at a distance of 10-40 microns.
HEPA devices resemble a folded accordion, fixed in the body. The design feature is explained by the need to increase the surface area to hold the maximum possible amount of fine dust particles. Some products have a filter material area of ??up to 3.7 m.
The main difference in HEPA devices is that the filtration process comprises the following stages:
- Interception. This phenomenon determines that dust only needs to touch the filter material to adhere.
- Diffusion. It copes with particles smaller than 0.1 ?m. In the course of vibrations, they leave the flow, touch the fiber, and settle.
- Inertial impaction. It deals with things bigger than 0.4 microns.
- Sieving. The particles bigger than the fiber spacing are left on its material.
If we put all the mechanisms in one graph, we will see that the product is most effective in capturing things with a size of less than 0.1 and more than 0.4 .
Pros of using HEPA filters
This type of mechanisms has the following features that ensure its use and benefit:
- Prevent air pollution in premises. The device helps keep it clean and fresh.
- Absorb dangerous particles that can cause diseases. Thus, it prevents humans’ bodies from bacterium and other microorganisms.
- Can be washed with water. It is easy to clean it and maintain its service life.
- Capture dust microparticles up to 0.04 – 0.06 microns.
- Are characterized by a longer service life than paper products.
- Do not impede the airflow.
- Its cost is low. The price of products is reasonable due to their high standards and specs.
The mechanism is vital for clean premises. They are used in pharmaceutical, microbiological industry, electronics industry, hospitals (operating rooms and surgical departments), NPP, food enterprises.
The technology allows creating highly efficient mechanisms, the main goal of which is to purify the air from fine particles. It perfectly copes with PM2.5 and PM10 (with a diameter of less than 2.5 and 10 microns, respectively). HEPA is not a brand but a filter class, which is defined by the international standard EN 1822-1: 2009.
