Filter Guide

Home / Filter Guide

When selecting a filtering device, a number of factors that can not be defined a priori and which can only be deduced from a correct and accurate risk analysis, must be considered.
The type of application, concentration, temperature, humidity, olfactory threshold, and individuality of the operator are just some of the aspects that contribute to the correct choice of the filter device.
