Health care is a daily matter, but most often we remember it when various diseases begin to threaten us. Meanwhile, during epidemics, early prevention of infection is especially important, and it must be carried out comprehensively. One of the most important parts of prevention is air disinfection in a house, apartment, office using special devices — ultraviolet irradiators or bactericidal closed-type recirculators.
This is a new type of device on our market, and the inevitable question arises: how are they useful and can they harm health? Let’s take a look at everything in detail.
Why are bactericidal recirculators useful?
The main health benefit of recirculators is indirect protection against pathogens of various diseases. The less foreign agents and allergens in the air, the longer a person stays healthy. So, what can recirculators-disinfectors do?
Destroy dangerous microorganisms
Only for hour a high-quality bactericidal recirculator destroys 99% of viruses, bacteria, fungi and mold spores that are in the air. This helps to improve the environment not only where there are many sick people by default (for example, in clinics), but also in other public places: offices and shops, child care facilities, cafes and restaurants, in elevators
In the context of the novel coronavirus pandemic, installing such a device is the best precaution.
The most sensitive to UV rays are Escherichia coli and cocci (streptococci, staphylococci, etc.). They survive no more than 0.1%, that is, one thousandth of all bacteria that were in the air before treatment. And the coronavirus that causes COVID-19 is 99% eradicated.
purify the air
Very often in a closed environment in the air during the analysis of samples, even from ordinary residential buildings, you can see an abundance of mold spores and allergens. With prolonged exposure to such conditions, a person is subjected to a constant attack on the respiratory and immune systems, which can lead not only to a local reaction, but also to respiratory diseases and a decrease in immune defense. Recirculators purify the air from harmful impurities, including dust and mold spores.
Research by scientists (1,2) has shown that respiratory allergic reactions significantly increase the risk of infections, including COVID-19. Due to the swelling of the mucous membranes and the constant need to fight allergens, the barrier function of the nasopharynx decreases and cannot withstand viruses.
To clean the air from such inclusions, a special filter must be installed in the recirculator. Yes, in Ballu ANTICOVIDgenerator built-in washable pre-filter class G3, which also cleans the air from dust, wool and other unwanted particles.
Don’t let viruses multiply
UV radiation in the recirculator destroys the DNA of a number of viruses and deprives them of their ability to reproduce. So even when you are near a sick person who is constantly releasing pathogens, the risk of infection is reduced.
Keep UV rays inside the appliance
The bactericidal recirculator is a closed type device. The housing is closed so that the radiation of ultraviolet lamps does not penetrate outside. The high-quality materials of which the Ballu ANTICOVIDgenerator is made — a steel case and UV-resistant components and paint — guarantee the safety of using the devices when people, animals or plants are in the room.
Although the recirculator cleans the air of various pathogens and allergens, they can also be deposited on surfaces (albeit in smaller quantities), and also transmitted by contact, such as SARS-Cov‑2. Despite all the advantages, hand washing and surface treatment will not replace such a device, and social distance must be observed.
Make the air better
Bactericidal recirculators are needed not only during epidemics. The urban environment, due to its dense conglomeration, is an aggressive environment for living, so air purification devices are needed in everyday life. Disinfection and filters make the air clean and safe, it is easier to breathe in the room and more pleasant to be in.
Cons of recirculators: myths and truth
Let’s deal with the main claims to bactericidal recirculators: what is true in them?
Effects of UV rays on the retina and skin
Prolonged exposure to ultraviolet radiation really damages the cells of the skin, and if it hits the retina, a person can lose sight.
But those who do not follow the rules for using quartz lamps are exposed to such a danger: such open-type devices can really only be turned on when there are no people in the room. And in closed recirculators, not only the case protects us from UV rays, but also labyrinth light reflectors at the air inlet and outlet into the device: they exclude the possibility of UV rays penetrating outside, which makes the device safe to use in the presence of people.
In order for UV lamps to produce rays with a high disinfecting capacity, they contain a small amount of mercury. But the higher the quality of the device, the less this metal is there. In addition, it is in a lamp in a solid cooled state and is enclosed in a glass capsule, not to mention the protective case of the device. In principle, the recirculator is as safe as the good old mercury thermometer.
Ozone release during operation
Those who have experienced the process of quartzization of premises are well aware of the characteristic smell of ozone that appears after the operation of the lamps. Ozone in large quantities is really harmful to people, it irritates the eyes, causes dry mucous membranes, coughing, shortness of breath and difficulty breathing. Prolonged exposure can cause serious pathologies of the respiratory system.
However, this only applies to quartz lamps. And bactericidal recirculators use ozone-free UV lamps that do not emit this gas and do not harm health.
Not all recirculators are the same, lamps and their characteristics can vary significantly. Air disinfector Ballu ANTICOVIDgenerator Equipped with 15W or 30W full-size ozone-free certified UV lamps. They emit UV radiation at a wavelength of 254 nanometers, which, according to research (3), most effectively destroys various pathogens, including the new coronavirus.
It is important to know that the effectiveness of disinfection directly depends on the service life of UV lamps. High-quality lamps retain their bactericidal ability for 9,000 hours of continuous operation, so the Ballu ANTICOVIDgenerator has a built-in operating time counter that takes into account the total operating time of UV lamps and displays the elapsed time on a digital display. When the operating time reaches 9000 hours, the meter will turn off the device and require replacement of the lamps with new ones.
Noise at work
Since bactericidal recirculators have not only lamps, but also fans that pump air through the device, noise indicators are an important difference between high-quality devices and consumer goods — it all depends on the manufacturer and model.
ANTICOVIDgenerator, developed and manufactured at the Izhevsk IZTT plant, it is distinguished by a combination of high performance and the lowest noise figure, less than 30 dB. So the device can be turned on not only during operation, but also at night — it will not interfere with sleep. You will sleep peacefully while ANTICOVIDgenerator destroys 99.9% of viruses and bacteria in your home.
Myths Busted: Closed germicidal recirculators offer many health and wellness benefits and are harmless in any environment. They keep the air inside clean and help us not to think about how many viruses and bacteria we can get with each breath — which means they improve not only physical, but also mental well-being.
