company news about Do HEPA filters need to be resealed after cleaning?

Whether the HEPA filter needs to be resealed after cleaning depends on the specific situation, the following are relevant instructions:

Whether it needs to be resealed after cleaning

In general: If the sealing material of the HEPA filter is not damaged during the cleaning process, and the sealing performance is still good, it is usually not necessary to re-seal. However, if the sealing material is damaged during the cleaning process, such as aging, cracking, falling off, or the seal is found to be weak after cleaning, it needs to be re-sealed.

Special cases: In some places with high cleanliness requirements, such as hospital operating rooms, pharmaceutical factories, etc., even if the sealing material seems to be intact, in order to ensure the sealing performance of the filter, it may be chosen to re-seal after cleaning.

The need to reseal

Ensure sealing performance: The sealing performance of the high efficiency filter directly affects its filtration effect. If the seal is not tight, unfiltered air may leak through the gaps, reducing the overall performance of the air purification system.

Prolong the service life: A good seal can prevent external pollutants from entering the filter inside, reduce the damage to the filter material, thus extending the service life of the high efficiency filter.

Sealing method

Liquid tank sealing: If the liquid tank sealing method is used, it is necessary to ensure that the liquid tank is clean when re-sealing, and correctly fill the sealing material, such as silicone, polyurethane, etc.

Knife-edge seal: For knife-edge sealed HEPA filters, it is necessary to ensure that the knife-edge and the sealing strip are tightly fitted without gap.

Rubber strip seal: Use a special sealing rubber strip to seal, ensure that the rubber strip is complete, non-damaged, and tightly fit between the filter and the frame.

In actual operation, according to the specific situation of the high efficiency filter and the requirements of the use of the environment, it should be decided whether to re-seal and what kind of sealing method is used to ensure the sealing performance and filtration effect of the filter.
