Biological safety cabinets commonly use High-Efficiency Particulate Air (HEPA) filters and Ultra-Low Penetration Air (ULPA) filters. But what exactly differentiates HEPA air filters from ULPA air filters in these cabinets? 1. Structure and Working Principle From both structural and chemical perspectives, HEPA and ULPA air filters are
HEPA Filter Market Outlook 2025: What Distributors and OEM Buyers Need to Know Introduction The demand for HEPA filters continues to grow worldwide in 2025, driven by stricter air quality standards, the expansion of cleanroom industries, and increasing consumer awareness of indoor air safety. For international distributors and OEM
Common Scenarios of Cleanroom Air Purification in Biopharma, Electronics, and Research Labs In precision instrument laboratories, a single particle of dust or a trace of microbial contamination can nullify weeks of meticulous work. Clean air is never just a background feature—it is the lifeline that determines the success or
Why Clean Air Filtration Is Critical to the Safety and Performance of New Energy Vehicles The range and safety performance of new energy vehicles (NEVs) are closely tied to the quality of their most critical component — the lithium battery. From electrode sheet preparation to cell packaging, every step
Understanding Cleanroom Filtration: From Pre-Filters to HEPA and ULPA Solutions Cleanroom filter requirements vary depending on the cleanliness level, and a three-stage filtration system—pre-filter, medium filter, and HEPA/ULPA filter—is essential. For the electronics industry, H13 and H14 HEPA filters are commonly used; pharmaceutical settings require antimicrobial HEPA filters; and
FFU Filter Units vs. HEPA Terminal Units: What’s the Difference? When designing or upgrading a cleanroom, selecting the right air filtration system is critical. Two common solutions—FFU (Fan Filter Unit) and HEPA terminal units—offer different advantages depending on your project’s requirements. Understanding the structural, functional, and performance differences between
Corn-Based Biodegradable Air Filter with Ultra-High PM0.3 Filtration Efficiency As industrialization and urbanization accelerate, particulate matter (PM) pollution has become a major threat to public health. Conventional air filters are typically made from petroleum-based synthetic materials such as polyester, polypropylene, or fiberglass, which are non-degradable and pose long-term environmental
What Is the Best Grade of HEPA Air Filter? If you’re shopping for an air purifier or designing a cleanroom, you’ve likely come across the term HEPA air filter. But not all HEPA filters are created equal. Understanding the differences between HEPA filter grades is crucial—especially when you’re aiming
Air Filter Replacement in Cleanrooms and Operating Rooms In cleanrooms and surgical suites, the timely replacement of primary, medium, and high-efficiency air filters is critical. But how often should these filters be changed? How can we accurately assess the lifespan of HEPA air filters in such environments? Based on
A Comprehensive Guide to Cleanroom HVAC Air Filter Systems and Practical Design The Role of HVAC Air Filter Systems in Cleanrooms Within any cleanroom facility, the HVAC system is the backbone of environmental control—complex, indispensable, and critical to success. Unlike conventional HVAC systems used in commercial buildings, the
