Summary • No pressure drop and effective air filtration • Permanently bonds to the filter fibers to form a new durable antimicrobial surface. • Non-migrating. It will not leach, off-gas or volatize. • Long-term, effective control of microorganisms which are commonly associated with building health problems. • Controls the growth of microorganisms on the air filter surface and has been shown in laboratory testing to lower microbial contamination in recirculated air.
