To check for leaks, the cover has to be fully closed and the latches set. You need to set the blower on high and try all the ventilation positions (dash, windshield, floor) while feeling all around the filter casing for any air coming out. As stated above it usually takes a 2 -3 trys to get the casing cover seated correctly.
