Scince specializes in the development, production, and sales of air filtration testing equipment, providing high-precision testing solutions for the filtration industry. Our core products are categorized into three major types based on testing applications:
1. Filter Material Testing Equipment – Designed to evaluate the performance of various filtration materials, ensuring filtration efficiency and resistance meet standard requirements.
2. Filter Element Testing Equipment – Used for testing the filtration performance and integrity of different air filters, including HEPA, ULPA, general ventilation filters, and engine intake filters.
3. Mask Testing Equipment – Designed to assess the filtration efficiency, breathing resistance, and leakage rate of masks and personal protective equipment to meet international safety standards.
Our products comply with global air filtration industry standards, including:
● HEPA/ULPA filters (EN1822, ISO 29463)
● General ventilation filters (EN779, ISO 16890, ASHRAE 52.2)
● Engine intake filters (ISO 5011)
● Masks and protective equipment (GB2626, EN149, NIOSH 42 CFR Part 84)
With in-house developed core technologies, high-precision and efficient testing equipment, and a deep understanding of industry standards, Scince provides reliable and intelligent testing solutions for medical, industrial, automotive, HVAC, and cleanroom applications worldwide.
ISO 29463 originates from EN1822, which defines EPA, HEPA and ULPA filters commonly used in industry. While ISO 29463 maintains the classification of EPA, HEPA and ULPA.But replace E10-E12, H13-H14 and U15-U17 with the following 13 filter levels. The ISO 29463 can't replace EN 1822, EN 1822 will continue to be valid.
EN 1822, ISO 29463, and IEST-RP-CC003.4 are three key standards for classifying and testing HEPA (High-Efficiency Particulate Air) and ULPA (Ultra-Low Penetration Air) filters. While they share similarities, they differ significantly in testing methods, particle size considerations, classification, and application scope. Below is a comprehensive comparison.
EN 14683 applies to medical face masks, focusing on bacterial filtration and splash resistance. N95 respirators follow NIOSH standards, focusing on particle filtration and facial fit.
