** ** Recently, a huge number of domestic and foreign air purifier ionizers have pumped air . This raises the question of which of these air purifiers to choose. So let us together with you be more competent in the choice of this or that model of air purifier-ionizer, as well as learn how to correctly ask questions related to this topic and choose exactly the device that is most suitable for your purposes and suitable for your pocket!
Consider devices that purify the air with electrostatics. The principle of operation of air cleaners of this type is based on the known physical law - Coulomb law. The ionized air in the device begins to move and picks up dust particles, which in turn receive an electric charge of a certain sign. Electrodes having the opposite potential attract particles of dust and aerosol, thus purifying the air, in other words, this type of product is called electronic, electrostatic or ionic air purifiers. It is these high-efficiency equipment that purifies the air from finely dispersed dust, soot and tobacco smoke, that is, particles smaller than 1 micron in size, which are most detrimental to our health.
The main characteristics of devices of this class are the volume of pumped air, the coefficient of filtration, the performance, which is the result of these three indicators, the volume of the room being serviced.
** The volume of pumped air ** is the number of cubic meters of air the unit passes through in one hour.
** Filter coefficient ** is the ability of an air purifier to retain dust particles inside (expressed as a%). The higher the filtration rate, the better the air purification.
** Product performance ** is the number of cubic meters of air that the device cleans in one hour, calculated by multiplying the volume of air pumped by the filter coefficient. By this definition of performance, you can easily calculate how long the appliance will clean your room. Remember, the average cleaning time should be about 2- 3 hours.
** Amount of room to be serviced ** is the maximum volume of room in which the air purifier is able to effectively maintain the air environment in accordance with sanitary standards in relation to dust.
Many manufacturers and sellers indicate that the product specifications are not the volume of the room being serviced, but the ** area ** is absolutely not correct, because any air purifier works with air that can only be measured by a characteristic such as VOLUME. In order to obtain the volume of the room where the appliance will operate, it is necessary to multiply the area of the given room by the height from the floor to the ceiling of the room. Now let's look at the technical specifications of the device and conclude whether it is suitable for your room or not.
So, ** the first conclusion ** - the main characteristics of the air purifier is the volume of pumped air, the filtration coefficient, the productivity. These characteristics must be adequate to the volume of the room in which the appliance will be used.
** The second issue is ionization **.
In the type of air purifiers we consider, simultaneously with air purification, its ionization occurs - it is enrichment of air with ions. ** Aeroions ** - positively and negatively charged oxygen ions. Ionizers are unipolar - let out airborne only one character (more often negative) and bipolar - both characters.
Most domestic manufacturers produce unipolar devices because they consider that only negatively charged ions (strengthen immunity, give vitality and health, etc.) are beneficial to the human body, but an important balance of negative and positive ions is strictly regulated by hygiene. requirements for the air composition of industrial and public premises. Ionization Concentration Unit - The number of charge units (of one sign or another) in one cubic centimeter. The higher the charge, the greater the concentration and, therefore, the more powerful the ionization.
