Good to know
  • Nominal 13 x 10 x 2 in. The #45 panel has the same nominal size but AprilAire lists it only for the Model 400 series; buy the number listed for your model.
  • The newer 620 and 720 humidifiers use a HydroCore cartridge, not the #35 panel.
  • AprilAire gives no fixed interval on the panel page; replace when clogged or when the Healthy Air App reminds you.
