PERFect is a novel permutation filtering approach designed to address two unsolved problems in microbiome data processing: (i) define and quantify loss due to filtering by implementing thresholds, and (ii) introduce and evaluate a permutation test for filtering loss to provide a measure of excessive filtering. Methods are assessed on two `mock' experiment data sets, where the true taxa compositions are known, and are applied to a publicly available vaginal microbiome data set. The method correctly removes contaminant taxa in `mock' data sets, quantifies and visualizes the corresponding filtering loss, and provides a uniform data-driven filtering criteria for real microbiome data sets
