The Aprilaire #35 Water Panel 2 Pack is the genuine OEM replacement water panel for the Aprilaire humidifiers: 350, 360, 560, 568, 600, 600A, 600M, 700, 700A, 700M, 760, and 768.


When used with the corresponding Aprilaire humidifiers, the #35 water panel is designed to last an entire heating season. Depending on how many seasons you use your humidifier, will determine how many times a year your water panel will need to be changed. Those who solely humidify during the winter season will only need to change the water panel once per year.

  • *Important Note: The change rate also depends on the hardness of your water. If you live in an area with hard water you may need to change the Aprilaire 35 water panel more than once a season.


The #35 water panel by Aprilaire is sized at 10" x 13" x 1 3/4" to ensure proper fit and optimal performance. 


Producing whole house humidification products since 1954, you can rest assured that Aprilaire products are manufactured with the highest standards in quality and reliability.

What is a Water Panel?

      A Humidifier Water Panel (sometimes referred to as a humidifier pad or humidifier filter) is the heart of your humidifier. It is made of layers of aluminum mesh with a porous, clay-like coating which allows the panel to soak up the water produced by the water distribution tray and turn it into humidity for your home. Without this porous material within the aluminum, the water would bead up on the metal and not be as effective at humidifying your home. 

As time goes on, the water starts to deteriorate the clay-like material and chunks begin to break off. Once you see signs of this wear it is time for a change! Waiting to change your humidifier water panel after these signs can drastically effect the output of humidity your system produces!
