In 1998, the Air Pollution Control Technology Verification Center (APCT Center) instituted a
Baghouse Filtration Products (BFP) Program as part of EPA’s ETV program. The purpose of the
BFP program was to verify the performance of baghouse filtration media on removing fine
particles (PM2.5), along with a limited number of other parameters, including pressure drop and
cleaning requirements of commercial-ready products. The expectation was that BFP verifications
would accelerate the market entry of verified fabrics and would thereby help improve the
environment as the new federal fine particle code was implemented at the state level. The BFP
program has been one of the more successful ETV programs, and the vast majority of filtration
fabric suppliers to the domestic bag market have participated in the program. In many cases, the
suppliers have continuously submitted newly developed fabrics for verification. A review of the
data from the program initiation to date is provided in this paper. In general, this review indicates
continuous improvement in the performance of the verified fabrics. A discussion of the
implications of this conclusion is also provided.
