Short summary
This study examines the effect of changes in relative humidity on measurements made by two different filter-based absorption photometers. Different filter loads, loading materials, and filter types are considered. It was found that both instruments react opposingly and with different magnitudes. One of the devices showed a variation in the dependence on the loading material. For each of the two devices, a correction approach is provided. Recommendations based on the findings are given.
