Ask any HVAC tech and he or she will tell you,,dirty filters account for more than 60% of all HVAC service calls.

That's for sure but don't spread it around, we make a lot of money fixing them.

Most filters do a better job of removing the finer particles after they get just a little dirty but you don't want them to get plugged bad enough to restrict air flow.
One thing I have always noticed is that most people think the air filter is part of the furnace when usually the filter slot is provided by the installer.
