"The WEB" furnace filter?

QUESTION:

I installed a passive, permanent electrostatic furnace filter called "Web Plus". The thing is several layers of foam in a plastic frame and is supposed to be rinsed clean monthly and reinstalled.
The filter has been in use over six months with both heating and cooling use. For cooling, I generally use a continuous fan setting, so the filter has definitely had plenty of air pulled through it.
The problem (if it is one) is that the filter has never gotten dusty or dirty. The rinse water is always perfectly clean and there is never any visible dust, lint, or hair on the external surface of the filter, totally contrary to my experience with both disposable pleated filters and powered electrostatics. A friend bought the same brand and his has remained clean as well.
Anybody have any comments about what is going on here?

ANSWER:

Sounds like you need to get bigger dust for the filter to catch or get a better filter to catch the dust you have. I think you answered your own question when you mentioned the pleated filter. I have the regular WEB filter, not the plus version. Mine certainly picks up allot of dust and is really dirty when I wash it.
Are you sure you only have one return?
