The quality of breathable air is of utmost importance for city dwellers, who have to endure stress and air pollution. But did you know that air ionizers have been around since the beginning of the 20th century? The concept originated from the work of scientist Alexander Chizhevsky, who studied aeroionization in biology. Decades later, British electrical engineer Cecil Alfred “Coppy” Laws developed the first air ionizer for domestic use. The main component of an air ionizer is a special emitter that creates an ionizing field through which dirty air passes.
A fan uses swivel blades to circulate air, which is useful for increasing ventilation in a room. Some fans also have an ionization setting. These devices circulate air and promote airflow while releasing negative ions. This type of ionizer blows air around the room quickly, so it cleans much faster.
The fan also promotes good ventilation, although it tends to be noisier and consumes more energy than an ionizer without a fan. Ozone, a lung irritant, is produced indirectly by ion generators and some other electronic air filters and directly by ozone generators. While indirect ozone production is a cause for concern, there is even greater concern with the direct and deliberate introduction of a lung irritant into indoor air. There is no difference, despite the claims of some vendors, between the ozone from outdoor smog and the ozone produced by these devices. Under certain conditions of use, ion generators and other ozone-generating air filters can produce levels of this lung irritant significantly higher than levels considered harmful to human health. A small percentage of air filters that claim to have health benefits may be regulated by the FDA as medical devices.
The Food and Drug Administration has set a limit of 0.05 parts per million of ozone for medical devices. While ozone can be used to reduce odors and contaminants in unoccupied spaces (such as eliminating smoke odors from homes affected by fires), the levels needed to achieve this are above those generally considered safe for humans. Unipolar ionizers are suitable for floors and offices. These devices release only negative ions, so they are considered to be the most popular. The fact is that all household and office equipment that surrounds a person creates positively charged particles.
So, to create a comfortable microclimate in the room, we can add negative ions to the air to achieve balance. Bipolar ionizers release positive and negative air ions. A unit like this is only necessary in spaces devoid of electrical appliances. In the modern world, when people are surrounded by appliances, bipolar ionizers are unnecessary. FrigorTec offers solutions worldwide for grain cooling, crane air conditioning, hay drying, thermal disinfection and heat pumps, and supplies the right refrigeration equipment, such as grain refrigeration units, crane air conditioning units, hay dryers, dehumidifiers and crane cabin refrigeration units.
However, slanted windows are not suitable for sufficient air exchange between indoor and outdoor air. An air purifier's filter and fan determine the type and amount of contaminants it can remove from the air in the room. The required air flow can be easily calculated by multiplying the length, width and height of the room where the unit is installed. For optimal performance, it is recommended to use an air ionizer after cleaning the air with a purifier and running a humidifier. Indoor air viral load can be significantly reduced through regular ventilation combined with the use of air purifiers. Air filter devices are often the only way to remove aerosols containing viruses and other contaminants from the air. A minimum distance from obstructions such as walls and large furniture must ensure that intake air can flow to the air purifier unhindered.
In addition, for more efficient operation of the ionizer, it is suggested to turn it on after cleaning the air with purifiers or to choose a purifier model with an ionization option - which AENO brand offers in its range. In response to COVID-19 pandemic people have been installing ionizers in offices and restaurants.
