Where Does All This Dust Come From?
Do you wake up with a stuffy head or nasal drip? Cracks in your ductwork or improperly sealed return air plenums can cause reactions. Does it seem that after installing a high efficiency filter the dust got worse? Maybe it really did! If ductwork is not properly sealed between the filter and the unit, dust maybe entering behind the filter actually making matters worse. High efficiency filters cause an increase in the air pressure behind them, which acts like a vacuum cleaner, and it can pull in dust from anywhere. Have Progress Energy evaluate the situation for you with a ductwork test to check for leaks.
