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.
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:
If you have any further questions regarding this or any of our products, please feel free to contact our customer service department at your earliest convenience.
