Filtration Efficiency and Standards

• Efficiency Testing: Air filters are evaluated using protocols like ISO 5011 to measure dust retention capacity (expressed as a percentage) and dust-holding capacity (in grams). For example, K&N filters achieve 96–99% cumulative efficiency under controlled lab conditions .
• HEPA/ULPA Classification: High-efficiency particulate air (HEPA) filters are classified under ISO 29463 and EN 1822. For instance, HEPA H14 filters retain ≥99.995% of particles at the Most Penetrating Particle Size (MPPS), while ULPA ISO 50 U filters achieve ≥99.999% efficiency .
