This case study presents a cost-effective HEPA filter testing solution for a manufacturer in Spain. By using the SCPUR SC-L8023 scanning system with a 0.3 μm particle counter, the client achieved reliable leak detection for H13 filters while complying with EN 1822 standards and significantly reducing equipment costs.
HEPA filter leak detection is essential for ensuring cleanroom performance and compliance with industry standards. This article introduces five common leak detection methods, including sodium flame, oil mist, DOP, fluorescence, and particle counting methods. Among them, the particle counting scanning method has become the most widely used approach due to its high accuracy, real-time detection, and compliance with EN 1822 and ISO 29463 standards. Modern systems such as automatic HEPA filter leak test benches provide reliable and efficient solutions for manufacturers and laboratories.
