Yes, air filtration is a great help. Our interior paint is eight years old and hasn't been touched. It looks like the day I put it down on the surfaces. There are a couple of places I occasionally wipe down certain areas like above some shower areas where lots of condensation occurs and maybe around the cook top area once in a while. If you are having to completely repaint whole rooms, either you need a paint brand that can be cleaned more easily and stand up to it or some way to better filter air from your heating system. Also unfiltered air from your heating system could present some negative health concerns.
