As per the documentation, you need a ttl index

For example, the following operation creates an index on the log_events collection’s createdAt field and specifies the expireAfterSeconds value of 3600 to set the expiration time to be one hour after the time specified by createdAt.

db.log_events.createIndex( { "createdAt": 1 }, { expireAfterSeconds: 3600 } )

When adding documents to the log_events collection, set the createdAt field to the current time:

db.log_events.insert( {
    "createdAt": new Date(), 
    "logEvent": 2, 
    "logMessage": "Success!"
} )
