Help!

Hi folks, little embarrassing but my folks moved into new house today and found this small contraption pugged into a wall socket - see photos attached. We are trying to work out what it is. Anyone recognize this thing? Air purifier maybe?

Cheers
Steve

Big cheer here round the table - thanks Jamie. Hilarious.... Been turing this thing on and off for a couple of day with no affect on air quality... Mean while we have been pressing doorbell and no one answers the door! Doorbell works a treat now we know to keep the 'air purifier' turned on!!! Doh! Thanks.
