To ensure its function, it's recommended to change the HEPA filter every 1440 printing hours. To do so, check the following steps: ![bcn3d-epsilon-hepa-filter](https://support.bcn3d.com/hs-fs/hubfs/Knowledge%20base/Draft/_MG_2524.jpg?width=600&name=_MG_2524.jpg)   **1.** Turn off and disconnect the printer | ![bcn3d-epsilon-turn-off-1](https://support.bcn3d.com/hs-fs/hubfs/Knowledge%20base/General/bcn3d-epsilon-turn-off-1.png?width=318&name=bcn3d-epsilon-turn-off-1.png) | ![bcn3d-epsilon-turn-off-2](https://support.bcn3d.com/hs-fs/hubfs/Knowledge%20base/General/bcn3d-epsilon-turn-off-2.png?width=321&name=bcn3d-epsilon-turn-off-2.png) | | --- | --- |   **2.** Inside the printer, pull the filter's lips in order to unlock the filter and pull it out from the filter support. ![HEPA-filter-disconnect](https://support.bcn3d.com/hs-fs/hubfs/Knowledge%20base/Draft/_MG_2522.jpg?width=600&name=_MG_2522.jpg) **3.** Insert the new filter in the support, paying attention that the lips of the filter are in a vertical position. ![HEPA-filter-connect](https://support.bcn3d.com/hs-fs/hubfs/Knowledge%20base/Draft/_MG_2523.jpg?width=600&name=_MG_2523.jpg).   **Conclusions** The printer will show a message when the HEPA filter needs to be changed. Some filaments emit toxic fumes that can be harmful to humans. To avoid symptoms like headaches, drowsiness, or fatigue, it is very important to change the HEPA filter at the moment when the printer asks you to do it. #### [Forum Community](https://support.bcn3d.com/knowledge/bcn3d-forum-community?hsLang=en) This article doesn't fix your issue?
