HEPA Filter Paper for Sale | High-Efficiency Fiberglass Filtration

Technical Specifications and Performance Metrics of Fiberglass Air Filter Paper

The performance of HEPA filter paper is quantified by several critical technical parameters that directly impact its effectiveness in various applications. These specifications are crucial for engineers and procurement specialists when evaluating hepa filter paper for sale:

• Filtration Efficiency (MPPS): Measured at the Most Penetrating Particle Size (MPPS), typically between 0.1 to 0.3 micrometers. This is the particle size that a filter is least efficient at capturing. HEPA filters must achieve 99.95% (H13) or 99.995% (H14) efficiency at MPPS according to EN 1822.
• Pressure Drop (Initial Resistance): The resistance to airflow across the filter media, measured in Pascals (Pa) or inches of water gauge (in. w.g.). Lower initial pressure drop translates to reduced energy consumption for fans and blowers, leading to significant energy savings over the filter's service life.
• Basis Weight: The weight of the filter media per unit area, typically expressed in g/m². It indicates the density of the fiber matrix.
• Thickness: The caliper of the filter paper, usually in millimeters (mm). Uniform thickness is vital for consistent performance.
• Air Permeability: The volume of air that can pass through a specific area of the paper at a given pressure differential, measured in L/m²/s or ft³/min/ft². This relates directly to pressure drop.
• Tensile Strength: The ability of the paper to withstand pulling forces without tearing, measured in N/15mm. Essential for pleating and overall structural integrity.
• Water Repellency: Important for applications in humid environments, ensuring the media does not degrade or lose efficiency due to moisture absorption.
