The primary filter is a commonly used filtration equipment in the air purification system, which is mainly used to filter large particles, dust, dander and other impurities in the air. However, over time, the primary filter becomes saturated and can no longer filter the air effectively, so it needs to be replaced regularly. So, how often should the primary filter be replaced?
In general, the replacement cycle of the primary filter depends on the environment in which it is used and the filtration efficiency. In the general indoor environment, the service life of the primary filter is usually about 3 months. However, if the indoor environment is poor, or if the filter is used for a long time, its lifespan may be shortened.
In addition, the replacement cycle of the primary filter is also related to its filtration efficiency. Generally speaking, the higher the filtration efficiency, the shorter the service life of the primary filter. Because high-efficiency filters need to filter more impurities, their dust-holding capacity is reduced accordingly.
In order to ensure the proper functioning of the air purification system, it is recommended to check the status of the primary filter regularly. If you find that the filter has become saturated or damaged, you should replace it with a new one. At the same time, in order to ensure the air purification effect, it is recommended to replace the primary filter every six months.
It should be noted that when replacing the primary filter, the model and specification that match the original equipment should be selected. If the size, material, etc. of the filter do not match, it will not only affect its filtration effect, but also may cause damage to the air purification system.
In conclusion, in order to ensure the proper functioning of the air purification system and the air quality, it is recommended to regularly inspect and replace the primary filter. At the same time, when selecting a filter, you should choose the model and specification that match the original equipment.
