I happened to notice the pre-2022 Laguna c-flux and p-flux dust bin bags show discontinued or out-of-stock for some time. I was in contact with Laguna and told the 2022 bags are now the replacement for prior models. They will try to get their web page updated, and I am sure this info will take a while to get down to the re-sellers. This is a small pet peeve of mine where a manufacture replaces a part number but is lacking in communicating that information.
