How long is the life span of activated carbon?

The lifespan of activated carbon typically ranges from a few months to several years, depending on factors such as the type of contaminants it is filtering, the concentration of those contaminants, and environmental conditions. In air purification applications, it may last 1-2 years, while in water treatment, it might need replacement every 6 months to a year. Regular monitoring and testing can help determine when it should be replaced for optimal performance.
