(grĭb′əl fɪltə)
See Gribble
flangen.
A particulate filter is a device composed of fibrous materials which removes solid particulates such as
dust, pollen, mould, and bacteria from the
air. This type of filter is used in applications where
air quality is important, notably in building ventilation systems and in engines.
A Gribble filter is such a device, but designed or positioned specifically by the manufacturer in a location that causes the maximum amount of dirt to accumulate in the filter, causing the Gribble flange effect to kick in: A correctly located filter
may require renewal every 24 to 36 months. A Gribble Filter gets
dirty in weeks, and is usually so well hidden or difficult to replace that the user continues to breathe in filthy unfiltered
air so that they don't have to pay a technician to find and replace the costly Gribble element.
Formerly seen as a
money grabbing device to benefit the manufacturer, now seen by Gen Y as no more than a friendly reminder that whatever the device is filtering, it's about
time we had a new one. With a snazzy corporate logo on it. In a different colour.
Ted: 'What's that filthy thing in your hand ?'
Bill: 'The Gribble filter from my
car. It failed early as anticipated, and the
car is now in the shop for repairs. Hope they forget to reset the Gribble Flange timer chip.'
