HVAC fan speed

[mep1811]

After winter of not using my AC it seems to be my fan is not blowing as hard as it used to be. Is there a test for the fan speed or volume of air being pushed out?
I did change the cabin air filter.

2013 200 Series

Thanks in advance

Is the motor making any strange noises? Remove your filter and switch between inside and outside air and note if they have about the same flow or if the outside airflow is much less.

With the filter out the fan volume is stronger on recirculate and reduced somewhat with outside air.
