  "abstract": "Devices, methods, and systems for event detection device testing are described herein. One device includes a memory and a processor to execute instructions stored in the memory to enable a filter-mode while the event detection device is simultaneously operating in a normal operational mode, cause a self-test module of the event detection device to generate an amount of test medium for a testing chamber of the event detection device, cause an air movement device of the event detection device to pass the test medium through the testing chamber, and cause the event detection device to perform an anti-mask test using the test medium to determine whether the testing chamber is blocked while in the filter-mode.",
