Comparison of membrane filters for recovery of legionellae from water samples

Abstract

The procedures currently used for isolating legionellae from environmental samples recommend filtration through a 0.2-μm-pore-size polycarbonate filter. In this study we evaluated the performance of 23 other filters composed of various materials and having various pore sizes. We prefer the 0.2-μm-pore-size Gelman Supor filter because of its high level of recovery, faster filtration rate, and ease of handling.
