Methods, apparatus, systems and articles of manufacture to filter process control system alarms based on alarm source type and/or alarm purpose are disclosed. An example method includes assigning a first subset of the process control alarms in a process control system to a first source type of the process control alarms. The first source type is associated with a first subset of user roles. The example method also includes assigning a second subset of the process control alarms to a second source type of the process control alarms. The second source type is associated with a second subset of the user roles. The example method further includes displaying alarm information associated with the process control alarms. The alarm information identifies the first source type of the first subset of the process control alarms and the second source type of the second subset of the process control alarms.
