Carpet/Vent Mildew

[FB]

I recently had a leak in my apartment that covered a small area of carpeting
with water. After trying to clean it, the manager replaced the carpeting and
padding and sprayed some anti mildw stuff on the walls and baseboard. I
still smell some musty, mildwy odors. I can't tell if it's in the floor or
coming from the air vents. I tried carpet cleaners and plain baking soda but
no luck.

Is there anything I can apply to the new carpet, padding and floor
underneath it to definitely get rid of any last mildew, and to the air vents
as well in case some mold got in. (I only smell the mildew near the vents of
the "accident" and not in any other area of the apartment)

Someone suggested "Sterifab." Has anyone heard of it or have any other
suggestions? TIA
