How often do I need to change the vapor pad?

We recommend replacing your vapor pad at least once per year. Minerals build up on the vapor pad over time, which in turn:

  • Reduces the pad's ability to absorb water.
  • Prevents the warm air from flowing through the pad (Warm air moving though the water-soaked pad causes the water in the pad to evaporate. It is this process that delivers moisture throughout your home via the home's duct system).
