What is the service life of an activated carbon air filter?
What is the service life of an activated carbon air filter?The service life of an activated carbon air filter is affected by many factors:Use environment factors - Air quality: In an environment with poor air quality and high pollutant concentration, such as near pollution sources (such as chemical plants, traffic arteries, etc.) or an industrial workshop with a lot of dust, the activated carbon will be saturated with adsorption more quickly, and its service life may be only about 3-6 months. In an environment with relatively good air quality, such as some clean office areas or places where the air is pre-treated, the service life may be extended to 12-18 months or even longer. - Air humidity: A high humidity environment will cause the activated carbon to adsorb a large amount of water, occupying its adsorption sites, thereby affecting its adsorption capacity for other pollutants. In an environment where the humidity exceeds 70% for a long time, the service life of the filter may be shortened to 6-9 months; in an environment with moderate humidity (40%-60%), the service life can be relatively normal. Use intensity factors - Running time: If the activated carbon air filter continues to run for a long time, its adsorption capacity will be exhausted quickly. For example, in some industrial production environments or ventilation systems in large public places that run 24 hours a day, the filter may need to be replaced every 6-12 months. In ordinary office environments with shorter daily operation times (such as 8-10 hours), the service life maybe 12-24 months. - Airflow: The greater the airflow, the more pollutants pass through the filter per unit of time, and the faster the activated carbon saturation rate will be. In high-flow ventilation systems, the filter may need to be replaced every few months; in-home air purifiers with lower flow, if the frequency of use is not high, may be used for 1-2 years. Activated carbon factors - Activated carbon quality: High-quality activated carbon has a large specific surface area, a developed pore structure, and a high adsorption capacity. The service life is relatively long, which may reach 18-24 months or even longer. However, due to its limited adsorption performance, activated carbon of poor quality may lose its filtering effect within 3-6 months. |
