Why Use Air Sanitizer?

Every day our houses and offices are contaminated by bacteria, dust, viruses, fungi, and pollution. With Air Sanitize, you can prevent most of the pathogens in your house. The reported picture is the HEPA filter AER1 on the right is the new one. In the second one, it represents one-month usage in the Air Sanitize. After just one month, the air filtration system was able to trap the different particles in the air and effectively better the air quality in our controlled environment. Over time the filter will capture 99.97% of all pathogens in the air; the UV-C light then can completely kill off the germs trapped in the filter. The action combined with the filter and the ultraviolet lights makes it possible to sanitize the environment in a short time and with low efforts. We found that air quality significantly improved; we had a decrease in air pollution by 20% in less than 30 minutes.

 

 

The reported picture represents the HEPA filter after one month of usage, under the microscope. The True HEPA filter is mostly made of the highly-dense paper, which is composed of very thin fibers with distances between 0.3 and 2.0 microns. The fibers are distributed randomly and oriented in all directions. There is a common assumption that the air space between the fibers must be as small as 0.3 microns so that the True HEPA filter can capture everything larger than this size. However, it is incorrect and impractical. With the smart design, the True HEPA filter can target the ultra-fine particles with a combination of three physical mechanisms:

  1. Inertial Impaction. The unclean airflow through the filter media of the True HEPA filter, but the heavier particles (or larger particles of pollutants) can not follow the gas flow streamline. Imagine, with their inertia of large sizes, these heavier particles travel along a straight path and soon captured by one of these fibers in the True HEPA filter. That is why the fibers must be distributed randomly. So the larger the objects are, the more chance they will be capture by the Inertial mechanism of True HEPA filter.
  2. Interception. This mechanism involves the particles with a somewhat smaller size, so it can easily follow the streamline and won't collide directly to the True HEPA filter's fibers. However, the radius of these particles is still larger than the distance between the streamline and the edge of the fiber (which is commonly 0.3 to 2 microns). Therefore, it will be captured by the edge of the threads.
  3. Diffusion. This mechanism is an essential part of the True HEPA filter and can remove even the smallest particles. Once the particles are as little as 0.3 microns, they don't strictly follow the streamline and move randomly due to the collision with the gas molecules (Brownian motion). So the smaller the particles are, the higher their freedom of movement, and therefore, the higher the probability that they will encounter the fiber. With decreasing particle size, the diffusion mechanism becomes more critical.

       

       

      Contrary to popular belief, not all HEPA filters are the same. There are significant differences in composition and utilization. For the AER1 HEPA filter, air reaches the screen, which uses the gradient composition of synthetic fibers to capture the charged particles. Rather than just trapping contaminants and having them build up over time, the UV light helps eliminate and reduce contamination. The UV-C light, combined with the filter, can effectively kill microorganisms, such as germs and viruses. UV-C light causes no harm to humans, and most importantly, the light bulb is hidden entirely inside the air purifier, so there is no way you will be exposed to the ultraviolet light. It all has to do with the UV-C light’s ability to destroy cells. UV light harms cells by destroying nucleic acids and disrupting their DNA, which either kills them or leaves them incapacitated. After prolonged exposure to UV light, cells are unable to perform their vital functions. With an air purifier with UV-light technology, the air is pulled into the appliance and passes through a fine filter. The air then passes through a small internal chamber where it is exposed to UV light. The UV-C light is not released into the room so that you won’t see it, nor will you be exposed to it.
