If you would like to convert your existing Electro-Air electronic air cleaner to a media style unit you can use one of the filter medias below. To determine which one you need, remove the collector cells from your existing electronic air cleaner. Now measure the space those cells took up. You will find something like 20" x 26" x 5" or less. Once you have that information click on each of the links below until you find the one that most closely matches the space you have available to fit the media filter in. When you are done converting your unit you will have removed 1 (or more commonly 2) collector cells and 1 (or more commonly 2) prefilters. You will have replaced all that with 1 media filter. Next you will turn off the electronic air cleaner power pack and if possible unplugged the power to the electronic air cleaner since electricity to it is no longer required.
