You're kidding yourself if you think a cheap fiberglass furnace filter is going to rid your house of dust, pollen or anything else. I mean, you can practically stick your whole hand through one of those things. So, spend a few bucks on a decent filter and put your heating and cooling system to work as a whole house air purifier. Just think, every time the fan kicks on, you could be sucking sneeze-inducing allergens out of the air.
