EPA Testing proves BHA-TEX provides the lowest emissions of any fabric!

The U.S.Environmental Protection Agency (EPA) provided filter fabric manufacturers the chance to test efficiency and pressure drop under the Environmental Technology Verification (ETV) Program. Each manufucturer was provided two opportunities for independent testing. BHA chose woven fiberglass with BHA-TEX (QG061), and polyester felt with BHA-TEX (QP131) for the testing.

BHA-TEX Fiberglass QG061 had the lowest emissions (PM 2.5) of any fabric tested: 0.002 mg/Nm³

BHA-TEX Polyester QP131 had extremely low emissions (PM 2.5) as well:  0.038 mg/Nm³

The test method used for testing is the “VDI 3926, Part 2” which has been approved by the American Society of Testing & Materials and is now known as "ASTM D6830".

BHA has the only fiberglass/ePTFE membrane fabric whose performance has been officially tested by the U.S. EPA ETV Program!
