  • How many microns does a HEPA filter capture?
  • Typically, HEPA filters capture up to 99.97% of particles as small as 0.3 microns. The dispersed oil particulate (DOP) scan testing, also known as filter integrity testing, or leak testing, is one of the most quoted methods by industry standards.
  • What is Pao testing in clean room HEPA filters?
  • PAO testing is the primary method for leak test in clean room HEPA filters. High-efficiency particulate air filters, known as HEPA filters, typically boast a collection efficiency exceeding 99.97% for particles sized 0.3 micrometers or larger. Employed as terminal filtration devices in cleanrooms, they ensure the provision of purified air.
  • What is a HEPA filter leak test?
  • The manufacturer generally tests the filtration efficiency of the HEPA filter, and the test report and certificate of compliance are attached when leaving the factory. For clean rooms, the HEPA filter leak test refers to on-site leak detection of HEPA filters and their systems after installation.
  • Why do I need to test my HEPA filter?
  • The installed HEPA filters require regular testing to ensure they remain leak-free. A good, leak-free HEPA filter is capable of providing many years of clean air but a leak, caused by damage to the filter, is a cause for concern. The main reasons for testing the filter are: 1. Qualification – installation testing. 2. Periodic testing for leaks
  • What are the different types of HEPA filter leak detection instruments?
  • There are two types of detection instruments: one is an aerosol photometer, and the other is a particle counter. The commonly used detection instrument in HEPA filter leak detection is an aerosol photometer (hereinafter referred to as the photometer), a forward-scattered linear photometer.
  • Why should you choose SEPs services for HEPA filter testing?
  • At SEPS Services, we offer comprehensive HEPA filter testing services. Our proficient technicians employ advanced equipment to evaluate your filters’ performance, confirming their efficiency and detecting potential issues.
