I am guessing cabin /pollen filter not fitted correctly and/or the cover is out of alignment that holds it in place.

No ,ano with no filter in place this sound is present

Any chance you disturbed one of the ventilation pipes?
Personally I have fitted 100s over the years in motortrade and what I have suggested is the most common cause, apart from disturbing a load of leaves or other rubbish when taking the old one out.

When the cabin filter is changed then leaves / rubbish / junk can drop into the fan housing causing fan impeller imbalance and thus noise / drumming / etc.

Drop the fan unit out/down and clean out.
