According to the National Institute of Allergy and Infectious Diseases (NIH), indoor air typically contains two to five times higher concentrations of pollutants than outdoor air, including dust, pollen, pet dander, viruses, bacteria, mold , and even second-hand smoke and chemical gases. In addition, with the "stay-at-home economy" of modern people and the popularization of electronic equipment, ionizing radiation and harmful substances produced by electronic equipment and human activities have also become the main source of indoor air pollution.
Therefore, in addition to simple measures such as opening windows for ventilation, more and more people have begun to use Air Purifiers to improve indoor air quality. However, many people do not know that the filters in air purifiers need to be replaced regularly, especially the Activated Carbon Filter.
activated carbon filter is a filter commonly used in air purifiers. It is mainly used to remove gaseous pollutants such as odor and volatile organic compounds (VOC). Activated carbon is usually made of charcoal, coal, grapefruit shells and other materials. The surface has a large number of small pores, which play a very good role in the process of adsorbing gaseous pollutants. However, as time goes by, the filter screen will gradually become saturated, the adsorption capacity will gradually decrease, and it will lose the ability to remove odors and purify the air. At this time, the Activated Carbon Filter Screen needs to be replaced.
Generally speaking, activated carbon filters need to be replaced every three to six months, depending on factors such as frequency of use, use environment, and air pollution level. When using an air purifier, you should pay attention to the recommendations and instructions in the instruction manual to understand when and how to replace the filter in the purifier.
In addition, if the activated carbon filter is not replaced in time, the gaseous pollutants adsorbed in the filter will be released into the indoor air, further polluting the indoor environment, and will also reduce the purification ability of the purifier and affect its long-term use effect.
To sum up, if you use an air purifier, especially one with an activated carbon filter, you need to replace the filter regularly to improve the purification effect and indoor air quality.
