        A:  They come in all sizes, home depot has the size you need, measure your frames, and yes use the aspen pads they cost less and work better, don't use the plastic/vinyl ones.

            A:  If you are on the page for a particular set of pads and scroll down to the bottom of the page, under the specifications it gives the sizes of the pads. They do vary so have to check which size you require and then match that to size of the pads in the specifications.

              Q:Can the pads be cut to size? I have an older swamp cooler that I can’t seem to find the exact size pads for.

              A:  I wouldn't cut these pads to size. They have a netting over them to keep the fibrous material altogether. If you cut them the pads would probably fall apart. They are however, very forgiving and if you could find ones that are close to the right size they could probably be adjusted by as much as 2 to 3 inches in width and height.

              A:  Thank you for your question. The pads cannot be cut to size because the mesh bag would be damaged. The bag is the covering for the aspen. You can, however, fold over the edges and they will fit in the louver doors. Thanks. - Sydney, Essick Air Products

                A:  Yes, they can be cut to size. It's messy though, so I would recommend doing it outside.

                by|May 5, 2023

                  A:  Yes they can be cut down to fit but I did leave them a bit long just to be sure there wasn't any open gaps anywhere

                  by|May 5, 2023

                    A:  They are sold a bit larger than the door itself because the water sags the pad. I bought this item as an OEM replacement for mine and it’s 2” wider and longer than my actual door size. They fit perfect. I supossed you could cut it but be sure not to cut in the mesh that holds it together. You can simply fold it upward as it came.

                      A shadow of what I expected. Loosely packed and thin. I ordered two and after trying one, totally dissatisfied. Took the second one back and trashed the first. Sorry, you asked.
