Black & Decker Dustbuster Replacement Filter WITH Pre-filter! Where to buy???

Finding a replacement filter for the Black & Decker Dustbuster's that included the plastic pre-filter had proven to be quite a challenge... until now!
This filter is compatible with the following models:
HLVC315J10
HLVC320J01
HLVC315B10
HLVC320B01
HLVC320J01-12
Here is the link! As I mentioned in video, it won't have a picture of the filter, but I already took the risk of ordering it and it IS the right one, happy day!
