Fiberglass Filter Paper, 1. H13, H14, U15, 2. HEPA filter materials - details see: https://www.machineto.com/fiberglass-filter-paper-hepa-filter-paper-10220248

It is comprised primarily of glass fiber produced by a wet laid process which is similar to that used in the production of paper. Our offerings rang from various ASHRAE grades (F6-F9), HEPA grades (H10-H14) to ULPA grades (U15-U16) with exceptional dust holding performance and provide with the highest available efficiency at a minimal resistance to air flow. It’s available in a laminated form to meet special air filtration requirements.

Applications:Industrial Cleaning Rooms, Food Processing, Hospital Operating Rooms, Genetic Research, Nuclear Containment, Pharmaceutical Processing, Chemical Processing, Compressor Inlet Filtration, Equipment Intake/Exhaust Air, Gas Turbine Air Intake, High-Temperature Industrial, HVAC System, Paint Spray Booth, Pre-Filtration for HEPA Systems, etc.
