The FHAP2040A1 is the larger PureA300 XL purifier. Extra noise in quiet or sleep mode can come from a filter that is not seated evenly, letting air whistle around it, or from a fan wheel that has collected dust.
If the purifier shuts off on its own, check whether a timer or auto-off setting is active before booking service. Persistent shutdowns or unresponsive controls point to the power supply or control board.
