We have two systems. The main part of the house is old and not built tight so we put an Aprilaire 2400 on it. I use the propriety replacements for it. In the addition where the audio system is, the construction is new and tight, so we have a setup that uses the 1-inch filters. I use the Filtrete filters with the red label ("Better"), which are one down from the one they call "Best".
