The supplied filters were submerged into a reservoir of General Test Water Type 1 (GTW1, NSF P231). The test water was drawn up through the filter at 3.50 inHg. Each filter was conditioned by the passage of 10 liters of GTW1 prior to being subjected to the filtration challenge study. The indicated challenge species were added to GTW1 (pH 7.5) and homogenized. Each filter was submerged in the challenge water and passed through each filter at an approximate flow rate of 833-909 mL/min at 3.50 inHg. Following the passage of 1 liter of challenge water through the filter, duplicate samples of the effluent were collected in sterile containers.
Testing performed using standard NSF/ANSI test methodology.
