When Heylo and Treehaus switched to Clean Core full-ceramic cartridges late in 2022, something unexpected happen. Our cartridge failure rate, which had been less than 0.5% for years, ticked up. But in most cases, we weren't noticing issues with the hardware. Customers were unaware that airflow in the cartridge was blocked by a protective feature of the new cartridges.
Fortunately, once customers are aware of the stopper element, removing it is as simple as pulling it off. You don't need to hang onto it - it is a safety mechanism that is useful during production. Check out this video below of how to remove.
