The replacement cycle of HEPA and activated carbon filters is not fixed, and they are affected by a variety of factors, including the frequency of use, the degree of air pollution, and the quality of the filter. The following is a detailed analysis of the two filter replacement cycles:

The replacement cycle of HEPA filter
General situation: under normal use, the replacement cycle of HEPA filter is usually 6 to 12 months.
Influencing factors:
Frequency of use: Air purifiers that are used for a long time every day, such as in some production workshops or laboratories where air purification is required continuously, HEPA filters will accumulate dust and pollutants faster, so they may need to be replaced more frequently. On the contrary, the replacement period of the HEPA filter can be extended appropriately for the air purifier with lower frequency.
Air quality: in the environment of poor air quality, such as frequent cities with haze days, or surrounding areas with pollution sources such as factories and construction sites, the content of dust, smoke, harmful gases and other particles in the air is high, and the HEPA filter is easy to be blocked and polluted, so the replacement cycle may be shortened. On the contrary, in areas with better air quality, the service life of HEPA filters is relatively long.
Filter quality: different brands, different materials and processes of HEPA filter, quality and performance are different, the service life will be different. Better quality filters may be more durable and have a relatively longer replacement period.
Activated carbon filter replacement cycle
General situation: The replacement cycle of activated carbon filter is usually between 6 and 9 months, but it may also change due to the different conditions of use.
Influencing factors:
Frequency and demand: if the filtration equipment is often used in daily life, and the requirements for filtration are high (such as the need to remove indoor odors, harmful gases, etc.), the activated carbon filter may need to be replaced more frequently. On the contrary, if the site of use is relatively less dust and contamination, the replacement period can be appropriately extended.
Filter quality: the quality of activated carbon filter will also affect its service life. Better quality activated carbon filters will last longer.
Maintenance: although the activated carbon filter is not recommended to clean, but appropriate maintenance (such as avoiding humid environment, regular cleaning of the pre-filter, etc.) can extend its service life.
Summary and Recommendations
In order to ensure the filtration effect of the air purifier and extend the service life of the equipment, it is recommended that the user formulate a reasonable filter replacement plan according to the actual situation. At the same time, regular cleaning and maintenance of air purifiers is also very important. When choosing an air purifier, you can pay attention to the index of particulate matter CCM (cumulative purification). The higher the value, the longer the service life of the filter is usually. In addition, different brands and models of air purifiers may vary, so it is best to check the product's instructions to determine the specific replacement cycle.
