Aprilaire vs. American Standard steam humidifier
Had an American Standard steam humidifier installed in the fall, as part of a system replacement, model AHUMD800. Now need to replace the steam canister, part number 8043RP. In searching online, I had a hard time finding the American Standard part; only one website, and it seems sketchy. But I also got a Google result for the Aprilaire 80 canister, which is for the Aprilaire model 800 steam humidifier. The online pictures of the Aprilaire humidifier, and associated canister, are IDENTICAL to the American Standard. So I'm wondering, are the canisters interchangeable? Lots of places sell the Aprilaire canister.
Second question: is it normal for these humidifiers/canisters to lose capacity over a season? I cleaned out the canister yesterday; it had significant mineral deposits. But I noticed that the electrode plates inside the canister appeared to be corroded and covered in scale. Wondering if that's causing reduced steam capacity that we're seeing.
