What are the key factors to ensure the quality of H13/H14 terminal HEPA filters?
Users do not know how to buy H13/H14 end-high efficiency filters, let's take a look at the key factors to ensure the quality of end-high efficiency filters.
First, test whether the material efficiency meets the requirements
Material is the cornerstone of high efficiency filter, and its efficiency directly determines the performance of the filter. The filter material used by the HEPA filter needs to meet the corresponding H13/H14 efficiency level. When purchasing filters, users should pay attention to the filter manufacturer's filter material detection parameters to ensure that each batch of.
Second, whether the filter production process is perfect and strict
In addition to the choice of materials, the production process can not be ignored. GB/T 13554-2020 "High Efficiency Air filter" standard puts forward detailed requirements for the production process and quality control of filters. A qualified filter manufacturer not only needs to have advanced production equipment and technology, but also needs to establish a sound quality management system to ensure that each process is strictly implemented in accordance with standards. Of particular note is the link of "high efficiency filter must be scanned by one", which requires enterprises to carry out strict performance testing on each H13/H14 high efficiency filter produced. The "high efficiency filter laser scanning leakage detection device" has become an important sign to measure the necessary strength of enterprises.
Third, whether it has the ability to detect leaks by on-site scanning
After the H13/H14 high efficiency filter is installed in the actual application environment, it may also leak due to improper installation, transportation damage and other reasons. Therefore, field scanning leakage detection is a key step in ensuring the final performance of the filter. Users should request the supplier to provide on-site scanning leak detection services, using professional equipment such as TSI particle counters to scan the filter and find and repair leaks in a timely manner. This process not only tests the technical strength and service level of the supplier, but also guarantees the user experience. It is worth noting that although domestic similar equipment may have more advantages in price, users should consider the reliability, accuracy and after-sales service of the equipment when choosing
