Recently, a client specializing in the production of HEPA filters faced challenges in maintaining product quality control. They sought to purchase an automated scanning device to test their H13 and higher-grade filters. According to the EN1822 standard, filters above H13 require MPPS (Most Penetrating Particle Size) testing, which typically necessitates a particle counter capable of detecting particles as small as 0.1μm. However, most counters available on the market for this type of testing are manufactured in the U.S. or Germany, and come at a high cost, causing significant concern for the client.
The client made it clear that their objective was to conduct factory tests on a batch of stock H13 filters. They were looking for a solution that would not only comply with the standard but also significantly reduce costs. After thoroughly understanding their requirements, the engineering team at **SCINCE** conducted an in-depth analysis.
We discovered that while MPPS testing traditionally requires a higher-spec 0.1μm particle counter, based on practical experience from many companies, for H13 filters, using a 0.3μm particle counter can also meet the EN1822 standard's leak detection requirements. Given that the client’s primary focus was on cost-efficient and fast testing of their stock H13 filters, we proposed they try our scanning bench equipped with a domestic 0.3μm particle counter.
The client showed great interest in this solution and decided to send their H13 filter samples to our company for verification testing. We used the **SC-L8023** scanning bench to conduct a comprehensive test on their samples. The results demonstrated that our equipment fully met the client’s testing requirements, successfully detecting leaks and ensuring the accuracy of the quality inspection. Through this solution, the client was able to avoid the need for an expensive imported 0.1μm particle counter and achieved significant cost savings.
This case demonstrates that by appropriately adjusting testing equipment configurations, companies can effectively control costs without compromising product quality standards. **SCINCE’s SC-L8023** equipment, with its flexible configuration and high performance, provided the client with a reliable testing solution, helping them pass their product quality verification while significantly reducing their investment costs.
Looking ahead, **SCINCE** remains committed to offering cost-effective testing equipment that enables clients to achieve high-quality production and stand out in an increasingly competitive market.
