HOLD IT UP TO A LIGHT SOURCE AND LOOK THROUGH IT. THE MORE PLUGGED IT IS THE LESS LIGHT WILL PASS. PLEATED FILTERS LAST LONGER BETWEEN CHANGES AS THE SURFACE AREA IS LARGER. UP TO 4" THICK PLEATED FILTERS ARE AVAILABLE. ANNUAL REPLACEMENT IS AVERAGE. THE 4" REQUIRES A FILTER CAN OF IT'S OWN BE INSTALLED. LC
