What is the replacement for the 2120/2140?

Consumer question:

We had our A/C system replaced last year. We had an Aprilaire filter system installed at the recommendation of the contractor. He said that the filters were Aprilaire 2120/2140 and a Humidifier Panel 400. What is your current replacement for these. I do not see them on any site selling your product.

Aprilaires' response:

Thank you for contacting us regarding replacement media for your Aprilaire products. The models 2120 and 2140 are two different air cleaners and would take different filter media. Please follow the links below for more information on the filter media for the two air cleaners:


Furthermore, please follow the link or navigate through the estore for information on the replacement water panels for the model 400 humidifier:

    I own model 2120 air cleaner. I plan on upgrading using kit 1213. What model air filter should I use after the upgrade?


    we only want to replace the #35 water panel on our Aprilaire. We do not need the complete kit. Is that part for sale separate?
    Thanks, Mark

    Thank you for contacting us with regards to your Aprilaire Humidifier. Item #35 refers to just the water panel. No other parts are included. Please let us know if we can be of further assistance.
