Humidifier Parts (Ceramic Disc) This is a humidifier I purchased in 2016. This year, the humidifier stopped working, and I thought it might be because I had never replaced the ceramic disc. I tried replacing it once, but the main unit still didn't work. I loved this humidifier, so I had to reluctantly get rid of the main unit. Since I only used the ceramic disc for a moment (it's practically unused), I'm listing it for sale, hoping someone else can use it. I plan to ship only the disc itself (the third picture). (The outer packaging has aged due to long-term storage, as shown in the photos.) *If you would still like the packaging sent with it, please let me know. Thank you. Ceramic disc and ring fastener replacement tool set. - Set includes: Ceramic disc, ring fastener - Purpose: Special tools - Material: Metal Thank you for looking.
