company news about How long is the replacement cycle of the primary filter and the high efficiency filter?

The replacement cycle of primary and high efficiency filters depends on a number of factors, including the use environment, the type and quality of the filter, and maintenance. The following is the recommended replacement cycle in general:

Primary filter

General environment: In ordinary office or home environments, the primary filter is usually replaced every 1 to 3 months. Because the air pollution in these environments is relatively light, the filter clogs more slowly.

High pollution environment: In highly polluted environments such as industrial workshops and hospital operating rooms, the primary filter may need to be replaced every 1 to 2 months. The air in these places contains more large particles of pollutants, such as dust, hair, paper scraps, etc., which are easy to clog the filter.

Frequency of use: If the equipment is used more frequently, such as running for a long time every day, the filter replacement cycle may be shortened. On the contrary, if the frequency of use is low, the replacement cycle can be appropriately extended.

High efficiency filter

General environment: In an ordinary clean room or laboratory environment, the replacement cycle of high efficiency filters is usually 1 to 2 years. These environments require high air cleanliness, but the pollution is relatively light, and the life of the filter is relatively long.

High-pollution environment: In high-pollution environments such as biosafety laboratories and pharmaceutical plants, HEPA filters may need to be replaced once a year. The air in these places contains a large number of bacteria, viruses and other microorganisms, which requires higher performance of the filter, and the replacement frequency needs to be increased.

The status of the primary filter: if the primary filter is well maintained and can effectively remove large particle pollutants, the replacement cycle of the high efficiency filter can be appropriately extended. On the contrary, if the primary filter is not maintained properly, the HEPA filter may clog faster and need to be replaced in advance.

Maintenance and inspection

Regular check: It is recommended to check the pressure difference of the filter regularly, and replace the filter in time when the pressure difference exceeds the maximum recommended by the manufacturer. This ensures that the filter is always in good working condition and avoids a decrease in air purification due to filter blockage.

Professional maintenance: For some critical environments, such as hospital operating rooms, pharmaceutical factories, etc., it is recommended that regular maintenance and inspection be carried out by professionals to ensure that the filter replacement cycle is reasonable and the air purification system operates normally.

Through reasonable maintenance and regular inspection, we can ensure that the primary effect filter and high efficiency filter work in the best condition, extend their service life, and ensure the efficient operation of the air purification system.
