Statistics indicate that more than 7 million people are infected with infectious diseases every year in the world, even vaccination does not save from the epidemiological danger, because new strains of the influenza virus do not pay attention to it. We all know that the disease is easier to prevent than to cure, therefore it is necessary to constantly prevent and disinfect our environment - a bactericidal recirculator can do this for effective air purification.


The modern modification of these products quite effectively destroys all known viruses, being an effective protection of public health. In order to find out the principle of operation of the device, as well as how this efficient work is achieved to destroy the causative agents of various diseases, you need to read our article.

What is a recirculator, why and where is it used

A bactericidal cleaner differs from an ordinary quartz lamp only in that it can be used in the presence of people, because it does not adversely affect all living things. During its operation, the activity of microorganisms ceases, the spread of infectious diseases transmitted by airborne droplets decreases.

Its design involves the use of ozone-free lamps with a special spraying of quartz glass, which prevents the excessive formation of ozone. An ultraviolet irradiator kills the viruses of staphylococcus, influenza, diphtheria, tuberculosis, supports aseptic conditions in rooms with people who are constantly in, but its activity does not negatively affect their well-being.

Security categories

The Ministry of Health has developed a list of premises that must be equipped with disinfection units with a certain level of impact on air masses:

  1. 90.0% are rooms for active children's games, various premises of educational institutions where classes are held, locker rooms of industrial zones and public buildings, where for a long time there is a large crowd of people.
  2. 95.0% - hospital wards, medical examination rooms and for recreational activities, corridors of resuscitation units.
  3. 99.0% - specialized rooms in hospitals and clinics, hospital wards, where there are patients with problems with the immune system; resuscitation departments, as well as various laboratories for the processing of tests, rooms where blood transfusions are carried out, pharmaceutical production workshops for sterile drugs.
  4. 99.9% - blocks for operations, maternity wards, sterile areas, children's wards and compartments for premature babies of the maternity ward.

All devices allow you to achieve the necessary sterility parameters in a fairly short time after their installation.

Scope of application

The number of devices is calculated based on the volume of the room so that they can effectively process. For example, if the room is 45 cubic meters. m, then for 95% disinfection it is enough to install one “Dezar-2” with a safe lamp from Philips with a resource of up to 8 thousand hours of continuous operation. In a room with a volume of 100 cubic meters. m. it is necessary to install two similar products or one more powerful “Dezar-3” wall-mounted.

The use of such products is allowed in public places: hairdressing salons, public laundry facilities, cosmetic and massage parlors, preschool institutions, in addition, they are used in educational institutions for various purposes to disinfect and prevent diseases. It is recommended to purchase a home recycler for a small capacity, and for dispensaries and medical institutions, a similar mobile device of the fourth or seventh modification with much greater power is considered the best option.

Principle of operation

Each device is equipped with a lamp whose rays of a certain length of 254 nm destroy pathogens, so the air becomes clean with a slight smell of ozone, the concentration of which is minimal and does not harm others. The design is quite simple: the hermetic casing is made of shockproof, chemically resistant plastic, the reflective partitions protect people in the room from direct contact with ultraviolet lamp radiation, the fans serve to circulate air.

The product must work constantly, passing and disinfecting air with a frequency of 70-100 cubic meters. m / h, the power varies between 100-200 W, while the noise from its operation is only 39 dB - this is not louder than a normal conversation, others practically do not respond to it. These devices not only kill microorganisms, but also act on their DNA, preventing reproduction. On average, cleansing is 95-98%.

For complete disinfection, the most powerful devices are used, in which up to five lamps are used, they are installed on special trolleys for mobility, and such products cost from 12 thousand rubles.

Variety of products

There are two main types of recirculator: open and closed type, the first is quite simple - its actions are aimed at effectively cleaning the environment and disinfecting the interior surfaces of the room. Such devices cannot be installed in everyday life, because they cannot provide a constant circulation of air masses. The second option applies everywhere without restriction.

HEPA-based cleaning systems are popular, but do not completely disinfect entrusted premises, because viruses accumulate in filtering devices. Only devices with ozone-free lamps completely eliminate bacteria, microbes and disinfect the room by almost 100%.

Advantages and disadvantages

Each individual air recirculator with the function of irradiating the surrounding space with the help of ultraviolet lamps of ozone-free type has individual advantages. The use of such devices guarantees the destruction of pathogens with an efficiency of up to 99.9%, while we get the following advantages:

  1. In our environment, the number of different pathogens is sharply reduced.
  2. The risk of disease during seasonal flu epidemics disappears.
  3. The acceptable level of microorganisms in the room is maintained.
  4. The content of bacteria and various viruses is reduced below the risk line of the disease.
  5. If one sick person appears in the family, all residents will not be infected, since all viruses exhaled by a sick person are destroyed instantly.
  6. Protection of all residents of the apartment from a sudden epidemic or biological sabotage.

In addition to tangible benefits, the use of similar devices has negative effects on others:

  • products are not intended to remove dust particles from the air;
  • the device does not guarantee the elimination of toxic chemical compounds that accidentally enter the room air;
  • for domestic needs, it is better to use stationary placement of devices, because powerful mobile options are sometimes equipped with mercury lamps, and they are not recommended for use in places where children are constantly located.

The main advantage of recirculators over quartz products is that they do not adversely affect humans, animals and plants, as well as the interior, modern decorative materials and electronic household or medical equipment.

Criterias of choice

Before purchasing such products, it is necessary to study the technical features, to understand the individual nuances of the devices, only then you can choose the best model for your home. All varieties of these original products existing today have the following characteristics:

  1. The greater effectiveness of eliminating viruses, it depends on the volume of the room where the device is installed, the time of continuous operation and the number of people present. In the instructions for use, the manufacturer must indicate and describe in detail all possible modes of use in order to ensure the efficiency of the destruction of microorganisms within 90-99%.
  2. Real performance and power. The first value is in the range from 20 to 100 cubic meters. m / h, and the power consumption is 15-100 watts. Low values ​​are for home use, medium for offices, and high for clinics, hospitals, and clinics.
  3. A variety. There are only three of them: wall, floor and mobile options, which are selected for reasons of convenient use and safety for others. If the apartment has children and pets, then the best option is on the wall outside the reach. Floor options are used in rooms where there is a safe place with excellent ventilation so that the product does not interfere with those present. The devices on wheels are used in a room where it is intended to be moved from room to room for efficient processing. After use, the device is stored in the utility room.
  4. Dimensions and weight. Mobile options have a length of up to 150 cm, and the width depends on the number of lamps and their location, this parameter in practice does not exceed 58 cm. Wall-mounted recirculators weigh no more than 5 kg, and mobile ones for clinics up to 10-12 kg.
  5. The number of lamps, their power. For home use, you must purchase a product with no more than three UV sources and designed for 15-30 watts. In more powerful devices, up to 6 pieces of ozone-free lamps of similar power are used.
  6. Assigned use resource. On average, no more than 8 thousand hours, for example, using the device for 8 hours every day, the lamp will actively work for about 3 years. For home use, where the device is rarely used for more than 4 hours in a row, the term doubles, and if you turn it on for only 2 hours daily, then you will have enough lamps for more than 10 years. Some products have a built-in counter that records the time of use, which is quite convenient for home use. In medical institutions, the time of active work is recorded in a special journal.
  7. The control panel is located on the body of the product, more expensive counterparts are equipped with remote controls.
  8. The case of ultraviolet bactericidal devices is made of durable plastic or polycarbonate, resistant to all types of chemically active detergents.
  9. Price policy. For home use, you need to choose a product in the price range from 3.5 thousand rubles, powerful mobile products will cost from 12.5 thousand rubles, it all depends on the number of lamps and power.

Permanent disinfection of residential premises is not carried out, because it is harmful to the younger generation, and many viruses mutate, so they can be immune to ultraviolet radiation. Doctors recommend the use of similar devices only during a surge of viral infections or after visiting a large number of guests during the holidays.

findings

To protect your home as much as possible from the negative effects of suspended pathogenic viruses and pathogens of various diseases of the upper respiratory tract, it is enough to purchase an effective device with ultraviolet lamps. Power must be selected based on the total volume of premises. For effective processing of all rooms, it is enough to turn on the product for 2 hours several times a week.

Longer disinfection should be carried out during inter-season outbreaks of acute respiratory infections and influenza in order to protect the entire family from the disease. If you are the owner of a private clinic, then you need to worry about buying more productive mobile equipment for processing corridors where patients are waiting for admission, devices similar to household products can be installed in doctors' offices.
