Air Purifier: Helper or Substitute?
When talking about the functions and limitations of air purifiers, we must first understand their basic working principles. Air purifiers mainly capture particles, dust, pollen, smoke and even some bacteria and viruses in the air through built-in filtration systems, such as high-efficiency air particulate filters and activated carbon filters. They effectively reduce visible dust and some allergens in the air.
However, our country must fully realize the limitations of this method of purification. First of all, air purifiers are mainly researched on solid particles in the air. For gaseous pollutants, such as carbon monoxide, ammonia, etc., their purification treatment effect is greatly reduced. Secondly, for certain bacteria and viruses, especially those microorganisms that can survive in the air for a long time, the filtration effect of the air purifier is also limited. This means that even in the environment where the air purifier is running, there is still a risk of contamination by some microorganisms.
Open windows for ventilation: “clear flow” of indoor air in winter
In winter, many people tend to keep their windows closed for long periods of time to keep the interior warm. However, this practice may actually have a negative impact on our health. Opening windows for ventilation is a key step in keeping indoor air fresh and essential for preventing respiratory diseases.
Opening windows can help reduce the concentration of potential pollutants in indoor air. Although air purifiers can remove dust and particles from the air, they cannot completely remove harmful gases such as carbon monoxide and nitrogen dioxide. These gases often come from combustion processes such as cooking and heating, as well as from the infiltration of outdoor air pollution. Regular windows can effectively discharge these harmful gases, while introducing fresh air and reducing the concentration of indoor pollutants.
Ventilation helps control indoor humidity and reduces the growth of mold and bacteria. Excessive humidity is an ideal environment for mold and bacteria to grow. By opening windows, moisture can be effectively vented, thereby reducing the risk of these microorganisms growing in the indoor environment.
"Air Disinfection": A simple guide to creating a healthy indoor environment
During the winter we often face problems with indoor air quality, especially with the use of air purifiers and fewer windows. In order to effectively improve the indoor air environment, it is particularly important to implement a simple and effective method-"air disinfection method". This approach combines physical and chemical means and is designed to reduce indoor air pollutants and harmful microorganisms, thereby reducing the risk of respiratory diseases.
Physical ventilation is the cornerstone of the "air disinfection method". Even in cold weather, opening windows at least twice a day for 15 minutes each time can significantly improve indoor air quality. This simple measure can effectively exchange indoor and outdoor air and reduce indoor pollutant concentrations, especially carbon dioxide, volatile organic compounds and other particles.
Keeping your home clean is another critical step. Regular cleaning of furniture surfaces and floors can reduce the accumulation of dust and mites. Vacuum cleaners that use filters can further reduce indoor allergens and fine particulate matter.
Proper use of air purifiers is also part of the "air disinfection method". Choosing an air purifier with an activated carbon layer can more effectively remove particles and chemical pollutants from the air. However, this does not mean that the need to open windows for ventilation can be ignored. Air purifiers should be considered an adjunct, not a replacement for window ventilation.
