Calling Psychics - Where's My Vacuum Cleaners Filter?

[AlanPacino]

That's it really. Dh used it yesterday and it's fallen out somewhere round the house and I can't find it anywhere and there's crumbs all over the floor!

Might he have emptied it out with the contents of the cleaner? (Mind you I'd be astonished to learn that there is a man alive who would ever think to empty a vacuum cleaner! )
