fibers stuff coming out of the AC duct

[centesme]

i recently got my AC cleaned but at times there are these fiber kind of thing coming out of the duct

what could this be.

i am concerned about my children health

how can i get it further cleaned as when i take the car to the garage to show the problem the fibers dnt come out.

so i go to the Volkswagen guys or can i resolve this on my own

thanks

VW A/C duct insulation from inside tend to age faster and start throwing out these foamy brown fiber part thru AC duct.

Re insulating all AC duct from inside is the only solution as cleaning it will not help. And might it its an expensive job and will get even more expensive if go to Al Nabooda.
