Questions & Answers

Why are these aspen pads listed on the California Prop 65 list of cancer causing elements? Is it because of the "wood dust" or the biodegradable stitching that holds the pad within it? I couldn't find what the stitching is made of. Thank you.

Answer This Question

Hello! The aspen pads are listed on the Prop 65 list because of the netting around the pads. If you have any other questions about our product, please email us at info@essickair.com. -Melissa, Champion Cooler

    What is the actual thickness of these pads? The listing says 1/8 inch (0.125")! This certainly isn't correct.

    Since I could not get an answer on this I ordered them anyway! They are about 1 1/4inch (1.25") thick and fit my cooler well. Why couldn't Home Depot have an employee answer the questions?

      They are the same thickness as the pads that came with the unit when new

          The Champion pads come in a lot of sizes, you can also fold them over if a little bit to big.

              I don't know why I got this question to answer but I did have a problem with mine. It would help if I knew what filters you were dealing with. My filters were difficult to locate as well and are for a Champion RWC35/RN35E. Filter #310085-9, internet# 206311578. Numbers are straight off the packing list. Hope this helps some.

                Nick, the Champion WC37 was built slightly different prior to 2009. The current WC37 uses this pad set and it will fit great. Unfortunately, there will be some instances (such as yours) where the pads will need to be 22 x 27 1/8". If this is the size of pads you need for your cooler, please contact our customer service dept. at 1-800-643-8341. Sorry for the confusion. Thank you, Tammie / Champion Cooler.

                  No, they are sown together. The aspen would likely fall out.

                    Hi, Marty. Thank you for your question. It is not recommended to cut aspen bags, as the mesh containment bag would come open. If they're only a little oversized, they can be folded over to fit. I hope this helps. - Sydney, Essick Air Products

                              Thank you for your question. Aspen is used in many industries, including the pet industry. We are checking with our supplier to see if they treat their wood with anything before selling it, but I do not think that they do. I will update this response if needed.
